Meet 'Balun One Nine', a small, cost-effective balun. An excellent way to attach a long wire or dipole antenna to the Ham It Up, or any other HF-capable radio, this 9: 1 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 for HF applications, but specifications are accurate to frequencies up to 90MHz +.
