Transponder Antennas

Transponder antennas from Comant, RA Miller, and TED.

104-12

Monopole Transponder/DME Antenna TED Part #: 104-12

$39.00

The 104-12 transponder antenna is a mono-pole antenna that has a top loaded sphere which creates a factor of reliability and safety for a shorter antenna. This antenna offers a voltage standing wave ratio of 1.2:1 at 1,090 MHz and less than 2:1 at 1,030 MHz when connected with a 50Ω coaxial transmission line. The 104 series antennas feature an omni-directional, vertical-polarize radiation pattern when mounted to the underside of the aircraft.

CI-101

Transponder Stub Antenna Comant Part #: CI-101

$129.00

The CI 101 is a top loaded stub, monopole, transponder antenna with a mechanically captivated radiator machined from solid brass for impact resistance. Contact power is made from beryllium copper, and metallic parts are plated with bright nickel for corrosion protection. Mounts through a single 0.6-inch diameter hole.

AV-22

Transponder Antenna RA Miller Part #: AV22

$99.00

This antenna is a direct replacement for the CI 101. The AV-22 is a transponder antenna which utilizes a "BNC" connector that allows for a smaller mounting hole. The antenna is designed to operate at speeds up to 350 mph and altitudes up to 50,000 ft. It has a drag force of 0.41 lb @ 250 mph.

104-17

Monopole Transponder Antenna | 978 MHz TED Part #: 104-17

$39.00

The 104-17 transponder antenna is a mono-pole antenna that has a top loaded sphere which creates a factor of reliability and safety for a shorter antenna. This antenna offers a voltage standing wave ratio of 1.2:1 at 1,090 MHz and less than 2:1 at 1,030 MHz when connected with a 50Ω coaxial transmission line. The 104 series antennas feature an omni-directional, vertical-polarize radiation pattern when mounted to the underside of the aircraft.

CI-105

DME/Transponder Antenna (960-1220 MHz) Comant Part #: CI-105

From $205.00

The CI 105 is a broadband and rugged antenna designed for DME or transponder use. The antenna assembly is encased in a glass reinforced polyester molded shell and has a standard two stud mounting configuration.

AV-74

DME/Transponder Blade Antenna RA Miller Part #: AV74

$148.00

This antenna is a direct replacement for the CI 105. The AV-74 is a broadband blade type antenna for transponder or DME application. The antenna housing is constructed of an acrylonitrile-styrene-acrylic (ASA) shell. The white color allows maximum performance without losses due to color pigments or unseen dirt.

CI-305

DME/Transponder Antenna Comant Part #: CI-305

$419.00

The CI-305 is a miniature, high-speed, DME transponder antenna. With a height less than 2.75 inches, the CI-305 features a very low drag frontal profile. This strong and lightweight antenna has a four-hole external mounting pattern and operates on 960 MHz to 1225 MHz.

CI-105-3

DME/Transponder Antenna Comant Part #: CI-105-3

$549.00

CI-105-3 is specifically designed for external applications using a three hole flange mounting, and includes a BNC connector.

CI-105-9

DME/Transponder Antenna (960-1220MHz, 1025-1150MHz) Comant Part #: CI-105-9

$419.00

Comant's CI 105-9 is a broadband and rugged antenna designed for DME or transponder use. The antenna assembly is encased in a glass reinforced polyester molded shell. Used in single and twin engine piston aircraft.
