Small size ideal for limited spaces
Rugged and waterproof
Receives signals with vertical and horizontal polarisation

Product Description

The 7031 Active Receive Antenna is an elegantly simple wideband receive-only antenna that is ideal where space is limited and the signal environment is crowded. The 7031 consists of a monopole antenna (125 cm/49 in) mounted directly to a high-dynamic-range, low-noise amplifier.

The amplifier is the key to the 7031’s outstanding performance. The low-noise, low-capacitance, and high-impedance input provides good sensitivity over the entire frequency band. The amplifier’s wide linear amplitude range and high 2nd- and 3rd-order IMD intercepts assure spur-free response even in the presence of multiple large-amplitude signals. Overload protection circuitry helps protect against damage from excessive input.
