Often referred to as Long Wire Balun, the WR-LWA-0130 adapter is used to match the impedance of a long wire HF antenna to a 50 ohm input impedance of a receiver. Such impedance matching usually results in a significant signal strength increase (up to 17dB in some cases, and approximately 5dB on average), compared to the long wire antenna connected directly to the antenna input of the receiver. While this is a general-purpose product, it particularly well suited to match the input of WiNRADiO shortwave receivers to the AX-05E long wire antenna.

Common-mode noise is generated by computers, lamp dimmers and other electric or electronic appliances. Such noise can be a problem especially in the lower portions of HF spectrum, where weak signals can be sometimes completely obscured by noise. The WR-CMC-30 Common-Mode Choke provides a means of reducing or eliminating common-mode noise from an antenna feedline, resulting in a considerable increase of the received signal quality.

The WR-BT-650 Power Injector (Bias "T") provides a means of injecting DC power in a coaxial cable, to power remotely-located devices such as active antennas, low-noise amplifiers and downconverters. It features a very flat frequency response, making it possible to use this device in a very wide frequency range, from 20 kHz to 650 MHz.

The WR-BT-3500 Power Injector (Bias "T") provides a means of injecting DC power in a coaxial cable, to power remotely-located devices such as active antennas, low-noise amplifiers and downconverters. It features a very flat frequency response, making it possible to use this device in a very wide frequency range, from 50 to 3500 MHz.

The WR-DNC-3500 UHF Downconverter 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 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 amplifier employs the latest Silicon Germanium Heterostructure Bipolar Transistor technology (SiGE HBT) to achieve its excellent performance, in terms of high gain, low noise figure and excellent third-order intercept.

The WR-DASP-2500 Dual-Action Surge Protector is designed to protect radio receivers from electrostatic discharges into the antenna input. Dual-action surge protection is accomplished by combining a high-performance gas discharge tube intended to absorb the bulk of the surge energy, with an ultra-fast-acting semiconductor suppression diode responsible for an exceptionally fast reaction time of the device.

The WR-ACD-1800 Dual Antenna Combiner serves to connect two separate HF and VHF/UHF antennas to a single antenna input of a wide-band receiver. This product also integrates a DC power injector for active antennas, for both HF and VHF/UHF antenna sections, eliminating the need for a separate 'Bias-T' circuit.

The WR-UBF-1800 Universal Broadcast Filter combines three functions in one package: An FM broadcast (88-108 MHz) band-reject filter, AM broadcast (0-1.75 MHz) band-reject filter, and a 20 dB attenuator. These functions (one at a time) are selectable by the user at installation time. This product is especially suitable for wide-band scanning receivers, where supression of broadcast bands is required in order to eliminate intermodulation interference from strong local stations.

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

The WR-AC-MC-01 durable mounting clamps, especially suitable for the WiNRADiO AX-71C VHF/UHF discone antenna. The mounting clamps are not supplied as a standard with this antenna, and can be ordered as a separate option. These heavy-duty galvanized mounting clamps make it possible to mount the discone antenna quickly and reliably on a mast.

The WiNRADiO WR-AX-91M is a high quality magnetic antenna base designed to securely mount a wide variety of antennas for mobile outdoor and stationary indoor applications. The base is equipped with a BNC socket and is ready to accept most types of antennas ranging from short tuned stub antennas to long telescopic and loop antennas both for receiving and transmitting. While this is a general-purpose product, it is particularly suited to the AX-06B and AX-07B antennas.

As a convenience to our customers, WiNRADiO offers coaxial antenna cable assemblies in standard sizes, suitable for a quick and easy set-up of a radio listening station. If you can't find a cable type you need, please contact us for a quote for a cable to suit your specific requirement.
