This device contains a high-stability local oscillator, mixer and filters to convert an incoming frequency range of 1700-3500 MHz down to 0-1800 MHz. This can be used to extend the frequency range of VHF/UHF receivers, both WiNRADiO and third party products.

The local oscillator is stable enough for the down converter to be usable even for narrow-band modulation modes, and has a low noise figure to be useful for professional as well as consumer applications.

The WiNRADiO Portable Power Source contains rechargeable NiMH batteries and intelligent charging circuitry to provide true portability to WiNRADiO receivers.  Suitable for all external receiver models, such as WR-1000e, WR-1550e, WR-3150e, WR-3500e and WR-3700e.
 

The WiNRADiO Telephone Control Interface makes it possible to control a WiNRADiO receiver remotely via a standard telephone line. Suitable for all external receiver models, such as WR-1000e, WR-1550e, WR-3150e, WR-3500e and WR-3700e.
 

The WiNRADiO ERD-1500 Electromagnetic Radiation Detector is an exceptionally efficient "RF Sniffer" developed to quickly and reliably locate sources of electromagnetic interference. The detector contains a miniature wide-band antenna with a quality amplifier and high-performance Schottky barrier detection diodes for maximum sensitivity.

This wall mounting bracket makes it possible to mount the G3E series receivers to a wall or under a desk, thus saving space. An elegant and useful accessory.

The G313/180 option extends the frequency coverage from the standard 9kHz-30MHz to 9kHz-180MHz. This makes it possible to use this receiver for narrow-band communications in the VHF range. The receiver's variable IF bandwidth makes this receiver particularly suitable for surveillance and monitoring of civilian and military communications.

The Wide-FM Option provides a separate Wide-FM demodulator. The Wide-FM demodulation is performed in hardware, using conventional hardware-based demodulation techniques, in order to ease the requirement of PC processing power which would otherwise be required for a signal of this bandwidth. In other words, the Wide-FM Option is an entirely separate receiver on its own right.

The WR-LNA-3500 Low Noise Amplifier is a ultra-low noise figure preamplifier designed to operate in the range of 30-3500 MHz. While it is ideally suited to WiNRADiO VHF/UHF receivers, it can be also used to improve sensitivity of most third party receivers.

The WiNRADiO AMFE™ Antenna Multiplexer and Frequency Extender fulfills a dual role of an antenna switching unit and a frequency down-converter, making it possible to easily interface separate HF, VHF, UHF and SHF antennas to a wide-band receiver, as well as provide frequency down-conversion for input signals up to 8599 MHz.
