What connector type is required for antennas?
By far the most popular connector type is the BNC Female because of its low cost and acceptable performance for low frequency antennas such as VHF or Marker Beacon. As antennas go higher in frequency, they require a more heavy-duty type of connector. The TNC is popular for most GPS antennas. Some very high frequency antennas used for DME, Transponder, or UHF Radiotelephone perform best when coupled with a TNC, C, N, or HN connector. These connector types show little loss and are generally more expensive.
