VHF/UHF 30-600MHz Wide Band Omnidirectional Antenna
product detail
Application
ZD-VOA-30/600M-NF is an ultra wideband vehicle antenna designed for use on all modern in-service military platforms, including armoured or so f skin, metal chassis or composite, wheeled or tracked.
The novel design gives it an excellent gain and radiation pattern across the whole frequency range. The antenna needs no adjustment for different frequencies as all the tuning elements are within the whip.
Bases are available to suit different mounting configurations with optional L1 & L1/L2 GPS.
