VHF/L-Band tuneable vehicle antenna, monopole/dipole, 1 m, 30-88 MHz, 1200-2000 MHz


The VHF3088T/L is an affordable high-gain low-profile antenna for use on vehicles.

In VHF the antenna has an equivalent performance to a 3.5 m whip although less than a third of the height.

The antenna has been designed to resolve all the problems associated with long whips on vehicles such as breakages, interference with high voltage lines or the need to be tied down when travelling at speed.

The antenna is a direct replacement for existing VHF whip antennas and uses the same NATO base support.

The very high performance of the antenna over the complete 30 to 88 MHz range is obtained through the use of low loss PIN diode switching of a low-loss radiating system. An excellent VSWR is assured through the use of a digitally controlled automatic control circuit.

The added L Band passive radiating element has class leading performance due to a stacked radiator system.

In VHF the antenna tuning time is less than 60 µs and so can be used with all modern tactical VHF radios.
