The Comant CI-2480-200 ComDat® is a dual-function VHF communications and GPS antenna designed to combine both functions within one radome. It provides separate connections for the two systems: a BNC connector for the VHF port and a TNC connector for the GPS port.

The antenna covers the 118–137 MHz VHF communications band and the 1575.42 MHz GPS frequency. Its integrated GPS preamplifier provides 26.5 dB gain, while the built-in harmonic-suppression filter is specified to provide 80 dB typical VHF harmonic rejection.
