The OMNI-A0140 banded manpack wireless high-power antenna is for interception of wireless communications. It is mounted on an N-type connector base, with a spring for shock absorption and flexibility. A glass-fibre tube contains the antenna RF board.
The array covers the GSM 900, PCS, UMTS/3G and WLAN bands. Full-specification 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.
The lowest feed point is elevated about 250 mm from the base of the antenna, allowing the signal to be radiated over the user’s head. This reduces absorbed power and increases field strength at the target.
