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.
Wing tip VOR antenna designed for smaller tips than Model 3 and with a 10 degree flare on the top portion and a curled aft portion. VSWR less than 2.0:1 over the frequency band of 108 to 118Mhz.
NOTE: When ordering wing tip antennas, order LEFT side antennas if installing on the bottom inside surface of a left hand tip or upper inside surface of a right hand tip. Order RIGHT side antennas if installing on the inside lower surface of a right hand tip or the upper inside surface of a left hand tip. Wing tip Com antennas should be installed only on lower inside surfaces.
Too expensive for what it is.
No, only one antenna is required for operation. The addition of a second antenna is only suggested when using 2 NAV radios.
