This multi frequency banded antenna is for interception of wireless communications. It is mounted using a NATO base flange, with a spring for shock absorption and flexibility. An e-glass tube contains the antenna RF board. The array covers the GSM 900, PCS, UMTS/3G and WLAN bands. Fullspecification coverage starts at 850 MHz, but there will be reduced performance down to 500 MHz. A 2-stack array of multi-band dipoles is used to provide gain at these frequencies, with a small down tilt to improve close-in coverage.
