Meet 'Balun One Nine', a small, cost-effective balun. An excellent way to attach a long wire antenna to the Ham It Up, this 1:9 balun has an SMA output port and high-quality spring-type terminal block input for your coax.
Balun One Nine includes an AntennaGuard varistor on the input, protecting your SDR setup from spurious ESD. The ESD protection is excellent--it passes IEC61000-4-2, an 8kV contact discharge test, with a response time of just 300ps.
At 39.2mm x 13.0mm in total size (including connectors!) this balun was designed to be light in weight and light on your wallet.
Very low insertion loss of -1.3dB (typical), with a maximum input power of +28dBm. Designed primarily for 160m-6m amateur bands, but specifications are accurate to frequencies up to 90MHz+.

- Great Solution For MF-HF ReceptionReview by gccradioscience
-
This is a great solution for MF-HF reception. When I did the test, the results were good even inside a first floor apartment. The first test I did was using it with a AM loop antenna and it pulled in some of the local AM stations. It does somewhat, but will be better outdoors for LW at least around 150 kHz to 520 kHz using a long wire or loop antenna. The second test was I built a medium sized delta loop antenna, and it pulled in some stations during early in the morning before sunrise. I tried the dipole configuration which was 2 long wires and the results was noisy, but believe me, it will be better when you place this balun outside your home in a sealed up container connected to 1 of the 3 types of antennas that you can build yourself. Also your communications receiver could benefit from this balun for great reception using the required adapter that you need to connect your cable to your receiver. Remember always ground your antennas for best low frequency and also use a lightning arrestor for bleeding off static dischages. NOTHING will survive a direct hit, so make sure that you disconnect and ground your outdoor antennas and also refrain from using any kind of wire or whip antenna during a electrical storm.

Lowered my noise floor quite a bit vs. connecting a long-wire directly to the unit with earth ground. Also gave excellent performance with a 300-ohm twin-lead folded dipole. (Posted on 12/28/2014)Value Quality Performance
