0.9 - 20 GHzUltra - Wideband Omnidirectional Antenna
Model Number QOM0.9-20S
The QOM0.9-20S ultra wide-band 0.9 - 20 GHz omni-directional antenna ismanufactured from aluminium and engineering plastics. Its compact size combined withits wideband performance makes this antenna extremely versatile and discreet.
A slight uptilt to the antenna radiation patterns mean that peak gain is acheived slighltyabove the horizon, excellent for communication to aircraft or from aircraft to ground. Aresonable gain performance on the horizon also ensures that the antenna has a widerange of other potential applications.
