New wideband VHF low profile antenna for transportation applications

Specialist Antenna Solutions (SAS) is pleased to introduce a new VLP300 VHF low profile antenna for bus applications.

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.

VLP300 VHF Low Profile Antenna
The VLP300 antenna uses an innovative design to give an omnidirectional pattern with vertical polarisation.
This antenna is wide band and does not need tuning in the field. It is housed in a tough ABS enclosure. The unit is supplied, fully assembled, sealed and ready to be fitted on its intended mounting surface.

The specification is as follows:
