VLP300 Series Antenna
Low Profile VHF Tunable Antenna (RFT-VLP-300-xxx-BNM-yyy-T)
Roof-top Bus, Railway/Light Rail, Car Antenna
The Low Profile VHF Antenna is designed to be mounted on vehicles such as buses, trucks and trains operating under severe height restrictions. The antenna uses an innovative design to give an omnidirectional pattern with vertical polarisation at the operating frequencies
Performance Advantage
This uniquely designed antenna offers mechanical strength and high electrical efficiency to provide maximum reliability and has been successfully designed and manufactured to meet the requirements of various operators
Key Features
- Omnidirectional radiation pattern, vertical polarisation
- Frequency Tunable in the field using a trimmer accessed underneath the antenna, to optimise performance in its working environment
- Can lend itself to change in frequency in its operating range
- The Radome is durable, resistant to Washes, UV Stable and Weather Proof
- 100% Quality Assured, Certificate of Conformity (CofC) available for each unit
