TheoryTheoryTheoryTheory ofofofof operationoperationoperationoperationAntennaAntennaAntennaAntennaThe antenna is one of the major elements which eect on the range of your broadcast.You will need to pay attention to the coaxial cable which will be described later.The Best position for a FM broadcast antenna is the highest place which from him you have line sight as far as possible withoutany interference fromOther buildings, mountains and other high object which may interfere your broadcast signal.Always remember that the critical parameter is not whether you broadcast 1W or 10W, but whether you are 10 or 15 metersabove ground.The best antenna for this transmitter will be a 50 ohm antenna which was matched exactly to the frequency you will need to use,but the price of those antennas may be high.For a low cost antenna, we recommend standard "dipole" FM antenna from any radio equipment which looks like 2 radiators incalculate length 75/freq(MHz),Example: At frequency of 100MHz, the length of each radiator will be 0.75m.

CoaxialCoaxialCoaxialCoaxial cablecablecablecableWe recommend using RG-58 which will t to the transmitter N-type power out connector.If you cannot nd it, use RG-213 but always try to nd a good quality cable, double shielded will be preferred.Try using the shortest cable you can, but never prefer shorter cable than higher antenna,The mention is putting the transmitter as close as possible to the antenna and never rolls "spare" cable instead of cutting thespares.

★Only for reference, also the covering distance is concern with the antenna and environment。

If you can match a good antenna to the FM transmitter, the effect will be better. The transmission range depends on manyfactors. The true distance is based on the sensitivity of the receiver, antenna of the receiver, and the building and otherobstructions, which are between the transmitter and receiver. And the distance will much more in countryside.
