Antenna Noise Blanker NR-1 - Ham Radio

- Ham Radio Surplus to requirements, as I upgraded station. Removes HF impulse noise directly at the antenna. No need for a separate noise antenna and coaxial. Removes noise from any direction simultaneously. (power-line-noise effective) Does not cause distortion in the presence of strong signals. Cleans out the waterfall too from noise on your SDR.
