C144 Series UHF / VHF Multiband Communication Antenna

The C144-1 models feature a single input covering VHF and UHF functions while the C144-5 model includes internal diplexing and provides separate outputs for VHF and UHF functions.

The unique electrical design of the VHF/FM band results in higher gain than would typically be expected from a broadband, fixed tuned antenna of its height in the 30 to 400 MHz range.

The moderate sweep angle design of the C144 antenna provides low drag while maintaining omnidirectional coverage in the upper UHF frequency range.
