The Digital Repeater is a modular solution utilizing the key components of the STx, SRx and ALPA power amplifier to provide a wide variety of solutions including:

n Cross band repeatern Multi Camera encoding solutionsn Local encoding/multiplexing at repeater siten Bi-directional radio links

Simple cross band repeater applications can be achieved to extend the working range of the VSTx and STx. This is of critical advantage when the tactical location, scene or event has dead zones making a reliable direct transmission difficult to achieve. The X-Tender digital repeater can be used as a simple repeater, receiving and then re-transmitting to another location overcoming the dead zone.

The X-Tender is an extremely powerful and flexible package. If the surveil-lance or event requires multiple cameras, the STx can be used to encode a local camera, to the repeater, and multiplex it along with the video source being repeated. This gives added capabilities and serves as a force multiplier delivering additional views on the same link.

GL Digital Fixed Link System

Modular architecture makes the IMT GL series the most advanced and flexible microwave fixed link on the market today. Available in all microwave bands from 2 to 23 GHz, GL systems can be configured as a split indoor/outdoor or as a completely indoor system. From duplex systems built in a single rack unit mainframe to the most sophisticated hot standby diversity systems, a wide and growing variety of modules makes it simple to fill any system requirement. All new modules are backward compatible with existing systems, making the GL link virtually obsolescence proof.

Take the latest IMT GL series modem card, the UNM/3. Like the UNM/2 modem it replaced, the UNM/3 is a full duplex card. But in addition to offering all the features of the older model, the UNM/3 offers two separate ASI inputs and outputs, as well as a transparent Ethernet port. Yet, it can be easily added to any existing GL Link to expand capabilities or for replacement purposes.

In addition to the highly versatile UNM/3, encoder and decoder modules are available that make it a simple matter to add a remote camera to a studio transmitter link, or to connect a remote news bureau. In fact, the system offers well over four dozen different modules that make it simple to design a system that exactly fills user needs. With our four port multiplexer and demultiplexer cards, a single radio can carry up to six ASI streams and Ethernet data.

The new SkymasterTX (SKTX) is a lightweight, full-featured digital COFDM video downlink transmitter built to address the unique requirements of aircraft downlink operation. The chassis design features either horizontal or vertical ARINC mounting. All of the connections and controls have been located on one side of the unit. This allows the SkymasterTX to be removed from one aircraft and installed in another with ease.

A unique feature of the SkymasterTX is a built-in GPS receiver. This allows aircraft position data to be downlinked to the command center for display on a moving map system. This feature allows rapid location of the aircraft.

The SkymasterTX can operate in a wide variety of bands delivering High Definition and Standard Definition video resolutions. The SkymasterTX can output up to 8W of RF power extending and improving link reliability. The SkymasterTX features COFDM digital modulation. COFDM modulation is unaffected by multipath – unlike single-carrier modulation formats such as FM, CDL or QAM.

The SkymasterTX has a built-in H.264 (MPEG-4) encoder or optional MPEG-2 encoder. MPEG-4 encoding is the latest encoding method. It requires 50% less bit-rate over MPEG-2 improving the reliability of the transmission even more. MPEG-4 also allows for the transmitting of High Definition video without sacrificing performance. IMT has taken great care with the design of the internal H.264 encoder. It has been designed with video quality as its cornerstone. The quality of the encoding rivals that of full-featured rack mounted encoders.

The ChannelMaster LITE features all of the great qualities of the ChannelMaster in a lighter weight package, specifically mission oriented for helicopter and aerial applications. This new two-box configuration results in greater than 40% weight reduction. The ChannelMaster LITE is available in single-band configurations, using frequency bands from 1.5-15.4 GHz. The encoder features adjustable long GOP encoding including IP and B frames improving video quality as well as a low delay mode. The encoder can be purchased as HD/SD or SD only. For increased flexibility a wide array of inputs are provided, including composite video/audio, SDI (with de-embedded audio), ASI and 70 MHz. The ASI input is ideal for use with an external encoder or to support digital repeater applications.

The ChannelMaster LITE features software generated modulation formats that are stored in circuit board PROMs (programmable read only memory). Available formats include — FM (NTSC/PAL), COFDM, VSB and single carrier QAM. As additional digital software formats become available, the PROMs can be easily updated. This feature increases the flexibility of the ChannelMaster LITE and helps avoid obsolescence.

Features:n Polarization: RHCP or LHCP (specify)

n Return loss: 14dB typical (1.5 to 1 VSWR)

n Connector: “N” Female

n Mount: Flange with through holes or helicoil inserts in (solid) base. (specify)

Applications:n Mobile ENG uplink/downlink

The quad-helix omni (QHO) designs bring the advantages of the characteristic quad-helix antenna radiation pattern to mobile ENG uplink/downlink applications.

The QHO features carefully designed helix parameters to optimize performance characteristics for such applications.

The QHO antenna provides a circularly polarized omni-directional radiation pattern with peak gain of 4 dBi at 30 degrees above the horizon, and then decreasing gain, with no nulls, as the elevation angle increases to the overhead 90 degree direction. The shape of this radiation pattern naturally compensates for the change in path loss as a mobile transmitter moves from the overhead direction out towards the horizon.

Good coverage is provided in this way from approximately 20 degrees above the horizon to the overhead direction.

Applications:n ENG Omni receive antenna for camera-

back/moving transmitter applications

The range of high gain omni-directional antennas comprise co-phased arrays of eight vertically polarized radiating elements to provide omni-directional azimuth coverage with a high gain, narrow elevation beam.

The planar printed circuit design features a unique system for maintaining consistent amplitude and phase at each radiating element tier, thereby achieving consistent high performance across the operating band. Planar compensating elements parallel to the main circuit board ensure a +/- 1 dB azimuth ripple in the omni pattern.

The antennas are housed in robust fiberglass tubes, and are provided with stainless steel brackets and U bolts for mounting.

High-Gain Collinear Omni Antennas



The slimline omni antennas are highly efficient, wideband, ground plane independent 1, 2, or 3 tier arrays of balanced centre-fed collinear dipoles, housed in a rugged, aesthetically pleasing, fiberglass tube.

High performance with consistent gain and radiation patterns across their wide operating bands results from a unique conical dipole and double isolating choke design preventing stray currents on the feed system.
