An array of loops is two loops for two directions.

Hi Guys
I uploaded the video on YouTube on this link, DropBox is not working.

I am going to try to get a horizontal loop aimed at 70 degrees up
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 are receiving the DX signal,

Clarification:
70 degrees refers to the AZIMUTH that the loop will be aimed for.
It will still be in a

Yes, utilities are underground, located by the road - north side of

This is adjacent to the proposed RX receiving area.
I can detect no noise coming from these underground lines.
South side of the property (adjacent to my backyard transmit towers) is idle

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

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 at least path one through
the wired connections.
Since you want to null two sources, you have
A couple of thoughts here, good or bad:

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. By using my
40 degree Beverage and a 3Khz roofing filter, along with turning the
pre-amps off
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 more
for spacing at right angles to that, it should be fairly simple. Use a 180
degree
I have received many suggestions and ideas on this subject.

Greg has offered an interesting idea that would integrate noise
canceling/nulling technology with a
