Model 7031

Wideband Active Receive Antenna

Wideband, 9 kHz–30 MHz
Low noise floor — good sensitivity for a compact antenna
High 2nd- and 3rd-order IMD intercepts, minimising spurious signals
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.

Product Description

The TCI Model 802W employs a flexible client-server architecture that provides a complete set of tools to carry out HF radio surveillance. The system rapidly acquires and describes any traditional or modern HF signal activity, and subsequently performs detailed analysis of specific signals of interest. The 802W can carry out this analysis manually or automatically in real-time or in delayed (post-facto) mode. The analysis includes detection, location, collection, classification and archiving of signal activities.

Under typical conditions the 802W system rapidly searches the HF spectrum using extremely fine resolution. When RF energy is detected, the system automatically determines the direction of the energy source and all other important signal parameters.
This information is then automatically archived for future analysis and can be simultaneously passed in real-time to operator client workstations. The operator at a client workstation tasks the system to find a particular Signal of Interest (SOI) with specific parameters. The system then processes archived or real-time data to find the SOI and its geographic position or location and presents this information to the operator.
