About Balun One Nine V2 Barebones - Small Low-Cost 9:1
For more details, please see the product page at nooelec.com! Balun One Nine v2 is a very small 9:1 balun/unun meant for attaching long wire and dipole HF antennas to your HF capable SDR, radio or Ham It Up upconverter. It has an SMA output port and 3 different terminal block input options (all included) for your antenna 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 38mm x 25.0mm in total size, this balun is a bit larger than our popular Balun One Nine v1, but also has better HF performance and can be used to even lower frequencies. It was designed to be light in weight and light on your wallet. Very low insertion loss with a maximum input power of +24dBm. Designed primarily for HF amateur bands, but specifications are accurate to frequencies up to 80MHz+.
