These antennas have been designed by Bob Archer from Torrance, CA utilizing concepts common to military aircraft and space vehicles. The antenna performance is superior to most in use today in private aircraft. The only requirement for max. Performance is that the antennas must be installed in accordance with the installation instructions. These antennas are designed to be installed inside fiberglass or other non-conductive wing tips or tail caps of metal or other conductive material aircraft.
This transponder/DME antenna is an etched copper clad epoxy circuit board dipole designed to be installed inside nonconductive air- craft without need for additional installation of a ground plane. The dimensions are 6" x 7" and it can be installed in the aft fuselage or the wings with the 6" dimension vertical.VSWR is less than 1.2:1 over bands of 1032 to 1090 Mhz.
Installed inside my Glasair far back in the tail. Allows maximum possible disrance from com antennas. Works perfectly with my Appareo 1090ES ADS-B out transponder. Will work with older mode C units but be advised it will NOT work with 978 or UAT ADS-B transponders. No ground plane needed!
The model 5 antenna must be installed with the 6" side mounted vertically and the 7" side mounted horizontally.
TED has released an ADS-B antenna. Please see part number 11-13561.
At least 3 feet spacing is recommended.
