Finding a single RX antenna system that nulls the neighbor noise sources at 90 and 270 degrees is proving to be a challenge. If the noise sources are really at 90 and 270, and you have 30 feet or mor

I have a strong source of 160 meter IX from another ham about a mile away at a bearing 330 degrees. The key clix and pumping of the noise floor make weak signal reception a real challenge at times. B

Thanks for the input. Yes, utilities are underground, located by the road - north side of property. This is adjacent to the proposed RX receiving area. I can detect no noise coming from these undergr
The issue with just combining noise antennas is, to phase antennas, there have to be at least two phase shift and at least two amplitude-sensitive paths involved. At least one path through air, and a
A couple of thoughts here, good or bad: 1. I can see the case for an array of loops. However, wouldn't it be less time-consuming --not to mention less expensive-- to just get an additional MFJ-1026 t

Hi Rick It is not recommended to tilt and elevate the loop. There is two reasons it improve the signal to noise ratio, First is the attenuation of the vertical component at the same direction you ar
