It depends...this is a complex (and interesting!) subject not covered in too many places. The prevailing theory (from a CCIR bulletin whose nomenclature doesn't come to me right now) is that "static"
Sure is, try reading various contest pubs...they take it to real depths. Thats because many antennas have poor elevation angle rejection curves. There is no free lunch in antenna performance. That ma
Scott is correct only if the noise is coming from the same elevation angle as the desired signal. In this case, he would be correct. In reality though, more often than not, I suspect that there will
15-10M. With a 4 ele yagi at 68 feet, 2.2dB of cable loss ( measured) and an 8dB NF receiver, I've never yet not managed to measure a minimum 4dB increase in noise in switching from a 50 ohm source t
I did not measure but was told that the stock TS-940 has a 12-13dB NF at 28MHz. The preamp at 1dB NF/10dB gain gave me a system NF of roughly 5dB. There were several times that the preamp improved th
