Signal Samplers are non-directional taps for sampling RF signals from a main transmission line, with minimal effect to the power level of the signals on the main line. The sampled port can be connected to Spectrum Analyzer for analysis and measurement, or connected to a low gain, distribution antenna in Signal Boosters systems to augment communications in buildings and tunnels. The 84-38-20-01 is a 132-174 MHz, -20dB sampler with N female throughput terminations and a BNC female coupling port.
