Cobham Antenna Systems' omni and directional antennas are used within many public service organisations for PMR and TETRA applications. Our bespoke designs result in antennas that are small, discreet and robust, suitable for harsh environments.
For example, our bespoke antenna model no. OA1-0.42V/1316, operating at 380MHz to 470MHz, measures just 239 x 395 mm, and is installed in the underground car park at London Heathrow Terminal 5.
Omni-directional antennas that operate at such low frequencies as this normally need to be very large, but the required location had a low ceiling height, presenting severe design challenges resulting from consequent size restrictions.
Once again, Cobham Antenna Systems came up with the best design solution – an unusual flush-mounting, omni-directional antenna that meets the needs of its location requirements perfectly, while still maintaining high-specification beam patterns. It is rugged enough to withstand extreme temperatures, and it is neutrally coloured to blend in with its surroundings.
