Two new omni antennas are now available, covering military L/S-Band and C-Band communications frequencies.

Antenna reference OA4-1.7-2.5V/1810 is a wideband omni, covering the frequency range 1.7GHz to 2.5GHz. It features high gain of up to 4.2dBi and vertical polarisation.

Complementing this antenna is OA4-4.4-5.8V/1662, another wideband omni antenna, covering the lower and upper C-Band, with frequency range 4.40GHz to 5.80GHz. This antenna has high gain of up to 5dBi and vertical polarisation.

The two antennas have been designed to provide high gain omni-directional coverage in frequency bands used with portable software defined radio (SDR) projects where four antennas have traditionally been used.

Using wideband biconical elements means that azimuth patterns have extremely low ripple whilst elevation patterns of 40° enables them to be used under most circumstances. Although the current models are ground-based, airborne versions will be available.

These antennas complement the company’s existing Ku band circular polarized omni antennas (which are used on ground and airborne platforms) and complete the set of L, S, C, and Ku bands for the portable SDR projects so that only three antennas (all with 4dBi gain) are required, reducing weight and inventory.
