Horizontal loop question

[Richard Fjeld]

Your posts about the horizontal delta loop prompted me to ask this question.  I know someone who has a 2WL horizontal loop erected about 45 feet high on the average. It is over a field of six foot high vegetation.  Will that absorb some of the signal?

I've always been a fan of the horizontal loop.  The Delta config works well.
Constructive and destructive effects on the radiation of the antenna occur
depending on the frequency, size of the loop and height above ground.
A 140 ft loop at 45 feet works well on 40 meters and up.
You get virtually omni-directional reception and a decently low angle
of radiation. It's an over-all winner design. Only thing
I like better out of wire is a Carolina Windom.

I have been quite pleased with this delta loop since I put it up about six
weeks ago.  The pattern does seem to be omni-directional and I notice that
the noise level appears to be at least fairly low.  I've worked several
stations (North Cook Islands, Bonnaire & Ireland) that were just above the
noise level that many other stations didn't seem to hear.  I originally put
up a 88' doublet but, upon presenting my new creation to the XYL, she
commented, "Is there any way to move that ugly black thing?" referring to
the center insulator which was directly in our view of the foothills behind
our house.  The aggravating thing about the comment was that she was
entirely right.  I sat up half the night trying to think of a way to
re-orient the doublet before it finally crossed my mind to take the surplus
wire I had sitting around and attach it to both ends of the doublet.  This
created the delta loop and allowed me to get the feed-point out of our
line-of-sight. That was a serendipitous turn of events for me because I had
never considered a loop before.
