The H21-1 dual VOR or dual marker beacon diplexer will permit operation of two NAV receivers form one VOR antenna or two marker beacon receivers from one marker beacon antenna. The unit is housed in an aluminum case and all circuit components fully encapsulated for vibration protection as well as waterproof protection.

The DM N4-7 VOR/LOC navigation antenna is a true center-fed balanced loop antenna with a high sensitivity and low bearing errors. The N4-7 system consists of two center-fed half-loops and a cable which enables a closed loop current flow allowing for improved signal to noise ratio and higher cross-polarized signal rejection. These rugged antennas have proven reliable service on aircraft such as Lockheed Jet-star, P-3A, and C-141 Starlifter, Bell UH1B helicopter, Sikorsky H34 helicopter, Convair 340, Aero Commander, North American Sabreliner, Douglas DC-3, Beech King Air and many other corporate and commercial aircraft.

The C63 series VHF communication antennas are designed with a high mechanical strength and have machine tapered aluminum alloy radiating elements. The C63 series antennas are available in both top mount designs and bent-back, low-profile bottom mount designs and are well suited for helicopter installations.

• C63 series antennas are supplied with a gasket and a double plate

The CI 211series antenna are high speed bent blade antennas designed as a low profile, top or bottom mount for large twins and medium jet aircraft. Skydrol and rain erosion resistant. The CI 211-1 & CI 211-16 have an extended frequency band (118 MHz to 154 MHz). The CI 211-L and CI 211-1L are equipped with leading edge protection.

The AV-924HS antenna was developed to be used with airborne FM transceivers typically used in first responder type aircraft providing a single antenna solution for the multiband transceivers. This antenna operates at VHF and UHF frequencies. It meets DO-160G, section 8, Category U requirements for robust vibration and is qualified for installation on helicopters with unknown related rotor frequencies. The AV-924HS meets the environmental requirements for flight speeds up to Mach 1 and supersedes the AV-924 part number. It is the same form, fit and function.

The CI 428-410 is a multifunction GPS and XM weather antenna designed specifically to meet the WAAS GPS Gamma 3 specifications required by the Garmin G1000 system. Enables primary navigation using WAAS GPS, including terminal navigation and approach to landing. XM weather antenna is designed for low gain systems such as the Garmin GDL-69/69A or as Heads Up systems with shorter coax runs. Confirms to the popular ARINC footprint, standard on many twin turboprops and business jets.

The H69-1 quadraplexer provides in one small lightweight component the ability to operate dual NAVs and dual glide slope receivers from one VOR antenna. The H69- 1 is housed in an aluminum case and all circuit components are fully encapsulated for vibration and waterproof protection.

• Allows operation of dual NAVS and dual GS receivers from one VOR antenna
• Reduced insertion loss and provides signal isolation

The CI 285 is a UHF radiotelephone antenna blade antenna designed for high-performing aircraft over the full frequency range of 400 MHz to 960 MHz. The antenna is encased in a low height, low drag, lightweight molded body and metal mounting base to ensure stable performance in tough environmental conditions.
