FEATURES
  • Navigation Antenna System
  • Designed to minimize bearing errors in the reception of VOR and ILS signals
  • Provides considerably more gain at the horizon (particularly during banks) than do fuselage mounted "deerhorn" or "vee" antennas
  • Substantially greater discrimination against vertically polarized signals
  • Provides much greater rejection of rotor modulation than can be obtained with other types of antennas when properly installed on helicopters
  • Provides better signal to noise ratios and smaller errors than is otherwise available

  • Designed specifically for light planes and helicopters
  • Lightweight rugged construction has been stressed
  • Constructed with round magnesium tubing
  • FAA and Military Specs: TSO-C40a, MIL-E-5400, MIL-T-5422

In relation to NE (New) parts, many OEMs change their prices and availability without any notice to dealers or the industry. Therefore, through the REQUEST or RFQ indication, we ask that customers contact us for the most accurate price and availability.

In relation to SV & OH parts, the used parts aftermarket in the aviation industry is not an infinite supply. It is a dynamic, constantly changing market that is significantly affected by and susceptible to highs and lows in supply and demand. Therefore, although we attempt to, at times, we are unable to predict the exact moment when an item may be available. Once again, through the REQUEST or RFQ indication on our website, we ask that customers contact us for the most current and accurate price and availability.
