Often referred to as Long Wire Balun, this device 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 17 dB in some cases, and approximately 5 dB on average), compared to the long wire antenna connected directly to the antenna input of the receiver.

The WiNRADiO WR-LWA-0130 Long Wire Antenna Adapter is designed to work on medium and short wave bands, covering a frequency range from 0.1 to 30 MHz. It is especially suitable for use with WiNRADiO shortwave receivers, such as the WR-G31DDC, WR-G303i, WR-G303e, WR-G313i and WR-G313e receivers.

Unlike most conventional antenna adapters, the WiNRADiO WR-LWA-0130 Long Wire Antenna Adapter employs a dual broadband transformer technique which offers an improved performance over single-transformer devices.
