[Antennas] phased loops

Sat, 5 Oct 2002 13:38:13 -0400

If you're talking about the M2 Horizontal loops that look like an open
square, I believe M2 also sells a phasing/mounting kit to stack two of
these.

I have both the 144 and 432 wire loop antennas.  Both are attic mounted and
were originally bought for sat work.  Before I retired, I had a pair of
custom made helix antennas - but alas the owner asked for them back about a
year later.

The M2 loops work great for weak signal stuff, AND are pretty good for even
voice at the horizon.  I added the radial kits to both for sat work, and
they improved the upward pattern greatly - but at the noticeable expense of
signals from the horizon.

I am thinking about a slightly different arrangement, where the radials
could be 'switched out' (isolated) from the antenna ground to turn on a
pattern that favors the horizon, and switched back in for a pattern that
favors higher angle for sat work.

If it works, I'll let you all know.
