( 30cm housing F-type connector – 0.27 Kg rigid )

INSTALLATION SETUP* (weight spec correction update Mar 2019 [270 grams] )

(Note: Some home stereo systems as do also some portable radios require to have a switch

activated on their back panel to activate the external aerial connector port)

(Note: this antenna can be used by alligator clipping the coaxial core to the base of a telescopic

antenna on a portable radio e.g. SW world band receivers) * some minor SW gather

RG6 -F-type connector : uses the coaxial core as the centre pin on the male cable connector

Typical performance (mounted properly is with element above roof level with no more than 5 meters of

standard RG6 (10 meters is ok but some minor signal loss) and no major signal blockage (e.g. tall close hill “or

high/medium rise or simply next door tall roof or within 40 meters”) within 100 meters nb: yachts boats re –

cliff faces) in a city environment for listening to a local 200 watt community stations has maximum 9 Km as

good reception listening quality in good weather (around 7km in rain) [tested through city-scape]

With the 1/16th

wave, another 200 watt community FM stereo station through city-scape is 17 Km away

and can receive it with listening quality at the last / least valuable consistent level during good weather

(receiver light flashes on a little). (Another 200 watt community FM stereo station 10 Km away, the receiver

light is on strong and consistent during good weather). Both transmitters use an Omn-directional (OD)

antenna .

Rule of thumb of Quality loss from rain storm: A receiver aerial has 2/3rds its’ maximum good weather

listening quality distance during rain to receive good listening quality signal, although the distance listening

quality ceases is more abrupt (sudden signal inefficiency) and closer to the maximum reception distance for

(related) the transmitter power the lower the power “something like” below 10 Kw.

Use an online (search for titles) "Degrees Minutes Seconds to Decimal Degrees converter" to find a

transmitter position and power level in the list from the ACMA in its' online PDF "Radio and

television broadcasting stations Internet edition 2019" Use “dd mm ss.s” fields in

Note: Many broadcast transmitter aerials are directional (DA) casting over only a sector (pie slice V shape)

transmission area, the transmitter location will be off to one side of the locality geographic service area, this

makes the idea that a receiver aerial twice as long is able to perform properly at twice the distance, in this

case (DA) it’s OK to think that but not quite an efficient guess ! Omni directional (OD) transmission is NOT an

efficient guess with that idea! Reception of a DA antenna transmission is not efficiently that far either.

Q; Why does an OMNI DIRECTIONAL AERIAL twice as long at twice the distance of final clear reception signal

transmission COMPAARED TO an aerial half the length at half that distance NOT HEAR the broadcast station

transmitter with any clarity ?

A: [ Simple basic (aberration) explanation without “Friis, gain, Db, loss and spacial 3D parameters” ] Apart

to some minor loss to the atmosphere as diffused static electricity during transmission, a simple explanation

without using “Friis calculation” is to understand an omni directional aerial or inclusive circular polarity omni

directional antenna transmission by signal travel along radius (signal path distance to receiver aerial) within

circular (broadcast) area-radius is each doubling of distance as radius of a circle shows that each time the

transmission to the aerials’ distance doubles it has much less than half the signal available every additional

comparative “set unit increment of distance as radius”.

Example: You would think that transmission signal strength to 10 Km would halve the signal strength by 20

Km (2 x 10). NO, it will be at around 14 Km the ‘signal is now half strength’ it was at 10km and at 20 Km is

only around ¼ the strength !

Double the broadcast area of a circle (distributed wattage) IS NOT (transmission to receiver aerial path) a

radius distance twice as far , “2 X AREA” RADIUS IS much less distance!

Pi(3.142) x radius squared = circle area (omni directional broadcast signal distribution)

10 x 10 x (3.142) = 314.2 sq Kilometres of distributed transmission signal

2 x 314 = 628 sq Km twice the distribution of wattage (waning – getting thinner)

So approx 628 sq. Kilometres of distributed transmission signal is required to know the signal has been

distributed to half its strength (wattage).

The following is the radius (distance from transmitter to receiver) for half transmission power in this scenario.

628 / 3.142 = 199.87 –do square root of 199.87 = 14.1 Kilometres approximately the transmission is half

strength ! NOT at twice the distance !

20Km x 20Km x (Pi 3.142) = “1256.8 sq. Km’ divide by 314.2 = a denominator of 4 meaning ¼ of signal strength

(wattage) available for the receiver antenna.

MOUNTING:

WARNING: Use only the bottom 10cm for mounting the antenna, Safely, Only the bottom first ten

centimetres 10cm of antenna housing tube base (approximately 3.8 inches) can be clamped for mounting !

Above that level DO NOT clamp for mounting !

WARNING: Do not locate the mount position within 3 meters of other metal roof objects e.g. tin ducts or

steel guy-wires or particularly roof air-conditioner housings (the antenna should be mounted higher than

this) – “follow this requirement as best possible”.

(when cutting coaxial around the core DO NOT leave shield wires or foil touching or near the core – brush

them back out of the way)

If you need more than 5 meters of coaxial, DO NOT extend with ordinary RG6 types , use a low loss cable

such as

(in order of best version for insert) RG213 , Special RG6 low loss, HFELX 2000, RG214.

Ideally use of as short coaxial length and distance as possible to the receiver set is best e.g. 5 meters

maximum, (between 5 meters and 10 meters has some minor loss of signal), so if you need a longer

coaxial

DO NOT EVER open the antenna housing! , “in basis it is waterproofed with sealant except the F

connector hole” , ”The base of the antenna has an F-type connector”, after choosing the mounting

location on the eaves of your house and placing the antenna on its pole (DO NOT allow the mount

pole to extend more than 10cm up beside the base of the antenna housing tube for clamping!),

THEN cut the RG6 Quad core coaxial 1 meter from the antenna to ensure ability to work with the

coaxial end to join to a low loss coaxial cable to lay to within 3 meters of the receiver and rejoin

with the originally removed section of RG6.

- Great trick for joining RG6 to RG213/U

Go to a hardware store and purchase two “straight tube – 240 volt twin screw conductor wire joiners of

around 1 ½ inch length” that will take the RG213 core diameter. Then cut the ends of the RG6 and

RG213 so core protrudes at the same length (approx 1 ½ inch) of the joiner device. Use a hammer to

gently beat the RG213 protruding core mildly flat.

Loosen the two screws on the joiner and place the RG6 core end completely through the pair of internal

screw down clamp faces protruding its end tip, then place the RG213 core completely through

protruding its end tip sitting over the top of the RG6 core. Tighten down the two screws crushing the

RG213 on top of the RG6. Seal completely by wrapping with electrical tape. Remember DO NOT allow

shield wire or foil to contact the cores !

After wrapping with tape, wrap a covering sheet of cooking foil over the complete joint expanse “four

times”, then seal over the top of that foil wrapping with electrical tape (makes a reasonable shield –

NOTE: do not wrap foil on the joiner directly, wrap foil over after the joiner is in place and sealed over

with electrical tape).

NOTE this antenna is not designed to be mounted upon a vehicle ,

for or while vehicle transit occurs !

Uses of this antenna are semi portable for caravans, motor homes, or permanent for home radio/stereo

systems, minor transmitter black-spots behind hills or minor transmission signal black-spots among buildings

with radio stations classified as servicing inside that location in cities and for outlying fringe suburbs minor

FM reception improvement. It is also ideal for hearing “adjacent local” community FM radio stations that

typically will have a low powered broadcast transmitter (generally only 100’s of watts transmission power

reaching only 5km to 10km absolute maximum useful audio quality after receiver set decoding of the signal).

Advice on installation:

If this antenna is used for AM reception on a standard home FM/AM non portable receiver the coaxial cable

central wire core should be plugged into the AM single slot.

If you need both AM and FM to receive local emergency or warning broadcasts (home radio/stereo sets often

do not offer an AM aerial / antenna socket) to increase reception reliability and signal. However, use of a car

Page 5 of 13

radio system and matching voltage accessory power pack powered by mains to operate it, this roof eaves

mounted antenna can be used for both AM and FM reception with a car radio set.

Use of a portable radio receiver with telescopic aerial for FM can also benefit from this antenna by fastening

an “alligator clip” to the coaxial core and clipping the alligator clip to the telescopic aerial base. Middle range

cost SW (world band radio) sets often offer at least the ability to use an external antenna for either FM and SW

and usually are a higher quality receiver for public broadcast FM radio.

If the coaxial from the antenna to the sets location exceeds 5 meters in such remote rural situations it is

advised/suggested that low loss coaxial cable of a type such as RG-213/U, the cheapest (expensive), special

low loss RG6, or H 2000 Flex (more expensive) or RG-214 /U (immensely expensive) be used until the cable

reaches the set or to 5 meters from the set, then swap with special connector adapter between to RG6 quad

shield for remainder distance. A suitable car radio coaxial plug terminator is required (for use of a power pack

and car radio indoor) but will generally only fit over a coaxial size of RG6 quad-shield and alike, so the latter

choice of transferring by either soldering together a joiner of the two cores between low loss heavy-duty and

RG6 for the last 3 meters is the better choice than fiddling an odd terminator plug (“perhaps”, it does not need

to be perfect shield termination at the end of the low-loss coaxial, the core and its wrapper insulator is

joinable into a standard car radio antenna plug by cutting back the shield covering sections sufficiently leaving

core and its insulator).

If you intend for a home radio/stereo system to use this FM/AM antenna

for that purpose, when locating it, mounting it into position, be sure that all of the antenna element tube is

above the house roof level (base of the element above house roof level where the eves meet rain gutter and

roof-top). The antenna is designed to operate directly vertically upright

If your home radio/stereo system has dipole wire-antenna terminals (two terminals for a long wire for the

radio), then you can clip the central single copper wire of the coaxial cable of the RG6 Quad shield to one of

the two terminals, However (while quite rare), some of the systems require a bridge piece of wire from one

dipole terminal to the other also, not simply clipping the coaxial central conductor wire to one of the terminals

alone.

DO NOT confuse the antenna “set coaxial/wire connector port” clips/screw-downs with one particular

clip/screw down port often labelled ”GRND” , this is the antenna GROUND wire port from set to exactly

that, ”earth” outside. (often referred to as an earthing wire)

If it is an “antenna ground” specified by your receiver set manual, then it replaces the Balun loop circuit system

of the receiver oscillator if used.

Most modern home radio/stereo systems usually now at least have a “standard plug type socket for use of

coaxial cable and plug” for either an AM or FM antenna (generally only for FM) rather than the dipole wire

system connectors (for this, refer to your home radio/stereo manufacturers’ instructions manual for that

model if both connector types present).

If you have a camper van / caravan or motor home and use a car radio system, you will need to terminate

the coaxial cable with the required plug for the back of your car radio / stereo system or whichever radio

stereo system you wish to couple this antenna to. If it is a home radio/stereo system in your camper van /

caravan or motor home you should refer to the above information.

Install Mounting:

...”be sure that all of the antenna element tube is above the roof level (base of the antenna element above

roof level where the eves meet the rain gutter and roof-top cover level)”...

“The lower 10 cm of the antenna mount base” can be used to U- clamp (U-bolts) to an antenna pole. In the

Eaves drill holes for the mount pole for suitable mounting methods such as coach-screws onto wooden

Page 6 of 13

eaves or washers and masonry bolts to attach the base to a brick wall to a ready mounted pole or antenna

mount bracket for a pole.

Coaxial Cable install handling (WARNING):

NEVER attempt to straighten or remove looping from a coaxial cable !, it must be laid into place by holding

it in position with a cable mount such as cable saddle clip/clamp and then “progressively setting the next

mount clip at intervals” of thereabout 30cm (one foot intervals), and so on...

NEVER stretch coaxial cable, it has zero tolerance at attempts to stretch it length ! The core wire will likely

break rendering the whole length useless for radio reception!

NEVER bend coaxial cable to a right angle or such like to go through holes or change direction when doing

layout into its permanent position !, it requires a 5cm(2 inch) radius minimum change of direction turn.

Sharp bending of coaxial causes severe signal distortion and loss of db gain. That would bring this antenna s’

reception output back to worthless effort to buy it !

Last things last:

When the antenna is fastened to the pole ,

be sure the pole is ‘not more than’ 10 cm (3.9 inches) against the bottom of the

antenna or it will start to obscure the internal reception element. Also do not have

the U – clamps positioned above that length of the base (simply the bottom end of

the antenna – the bottom of it is where the female F Connector is)

When the coaxial is connected to the antenna by its F – Connector pair (as shown

in the pictures) ‘be sure that there is a small curve of coaxial from the antennas’

connector to the first tied down point of the coaxial cable on the pole’ NOT a

stretched or straight piece of cable between those two points, if it is too taught the

coaxial can pull out or be stretch damaged in high wind !

After the coaxial cable is fastened by its’ connectors , be sure to wrap good quality

outdoor electrical tape from the base of the antenna at the female connector

“around the female connector continually all the way onto the coaxial cable below

Page 11 of 13

to seal the connection from rain , moisture , humidity” that can cause signal loss

from corrosion.

The connectors are not weather proof until they are sealed with outdoor/electrical

plastic tape

When mounting with the two U-clamps use eight nuts 4 tightening and 4 lock

down nuts to tighten against the first fastening nut set to prevent loosening.

o Tighten firmly to mount pole, do not crush !

o Ideally the pole should reach the antenna above “all roof obstacles” to a

height of 4 to 6 meters above the ground final elevation.

If you want to use this on a 4WD or any other vehicle

( No warranty (retrieve-inspect-replace) or blame upon the manufacturer or seller regarding malfunction of the antenna accepted after committing the following procedure to mount to a ute, 4WD or any other type of vehicle )

Rollbar and Bullbar mount only for road and 4WD vehicles and tray inclusive cabin-tray-guard pipes, or for trucks, can be the upright mirror of truck with at least 12cm of upright mirror mount strut tube clear available to mount the antenna that will not affect the safe operation and structure of the mirror, neither obstruct driver visibility and finally not cause the antenna excessive inefficiency at its operation.

1.(DO NOT remove the antenna cap) file the paint away under the pole cap rim (where the cap meets the tube) near the top and from the under rim of the cap. THEN, glue the cap and pole-tube around that rim to join them with an "extremely/immensely strong PVC glue" ( * do not remove the antenna cap ). (However a standard road vehicle or farm vehicle that does not require 4WD actions is not affected by instruction No 1 above)

2. as part of the permanent mount from the position on the vehicle, the antenna base at the upper and lower screws should be the grab points (simply not directly on/over the screws). Between the screws is better than above and below, but be sure the clamping system objects grip onto the antenna pole applying the pressure from within a few millimeters of the screws. ( e.g. pole U-clamps - note: always use 4 nuts per u-clamp 2x tightening and 2x lock-down).

3. (for Bullbar) the top 21.5 cm of the antenna including the cap contains the element system and should be at a higher level than the bonnet of the vehicle (the bottom 10cm of antenna are acceptable to obscure).

3b. (for rear Rollbar on Ute types) In likeness, the top of the antenna because it is rigid should not be protruding above cabin roof height, but mounted away from the cabin on "the base (lower end) of the angular strut of the rollbar" toward mid tray length.

Page 12 of 13

4.WARNING , Do not mount the antenna too near any objects that heavy

braking, heavy vibration / shock or heavy maneuvering causes the antenna pole to strike/contact other solid objects that could or would damage the antenna.

After full mounting and connection , using high quality super glue, glue the coaxial to the metal rim of the connector to prevent slippage, and tighten coaxial with a plastic "wire tie" to prevent the coaxial flapping in wind or slipping and pulling on the connector. (add weather gel sealant around the connector rim on the antenna and coaxial connector to waterproof)

Other considerations

Note: “A mild rain storm near the receiver geographically is worse” against signal than “a

heavy storm near the transmitter” because the signal weakens as it travels outward to the

receiver, so “it is at its weakest for purpose” near the receiver and cannot reach if too

weak from a mild rain storms’ blockage of path.

If you want to be sure that the “maximum distance rating” can be obtained or are

attempting to hold as much reception quality of a station below 40Kw over a long distance

for as long as possible, use of 1. A “larger size long distance receiver set” with more and

better quality refined signal extraction stages should be used WITH 2. at least some

reasonable “low signal loss” (low attenuation) coaxial cable type such as “Special low loss

RG6”.

A good example of better quality receiver set with more refined signal stages is any large

multi band SW (Short Wave) radio at the top end of price OR any reasonable quality brand

name permanent (large non portable) located home stereo “AM/FM/DAB radio receiver –

amplifier “combination section.

The previous often are a point with manufacturers they are able to have the internal

space to add all the required extra refinement stages and filtering unlike cheap portables

and pocket size radios, sometimes inclusive good booster stages for varied levels of weak

stations to produce near good quality sound signal decoding.

Although “large multi band SW radios” have only one speaker and sometimes no bass

treble or tone knob, these for most, do output stereo through a jack connector and switch

that can be connected to a dual input channel audio amplifier (e.g. AUX input connector

pair) and audio equalizer set (5 band or more for good discrimination) to produce high

quality sound or improve weak station audio output for use.
