Abstract
A combination antenna for aircraft application is disclosed. The antenna has a shell similar to that of a conventional VHF communication antenna, but it houses a monopole VHF and a volute GPS antennas. Provisions are made to enable the GPS antenna to be situated beneath the VHF antenna, but yet have full view of the upper hemisphere and avoid interference even though no structural shielding is provided. The combination antenna is mountable on the pre-existing base used for the conventional single VHF communication antenna and is operable with the pre-existing cable used to transmit the signal of the replaced single VHF communication antenna.
