The VLP300 is a market-leading, proven VHF low profile antenna designed to be mounted on vehicles such as buses, trucks, coaches and vans operating under very severe height restrictions.. Until now, there have been three versions available: a single band antenna, a field-tunable antenna and a dual band (dual resonance) antenna.
The single band antenna has now been enhanced to become a wideband antenna offering 10 MHz of bandwidth at -10 dB return loss or better. This means that it is effectively widebanded enough to cover the spread of both Rx and Tx bands in many VHF transportation applications.
