Default Outdoor Loop


I have a loop in the attic, but I decided to take a loop outdoors, so I built a 11 meter quad loop and parked it horizontally at 30' elevation.
It is only 10' above the roof ridge. Here are some photos of the building process. Just ask if you don't follow the photos.

Looks good, just need a director and reflector and you will be rocking.

Yep. Maybe later. The difficult part is done.
With the SWR meter it is 1.1:1 on all CB freqs.
I'll get the analyzer on it maybe tomorrow.

Just a bit surprised that the metal "X" in the middle didn't make the SWR impossible.
Most of the 'Skypper' loop antennas use fiberglass.
Want to hear you on the air with it Homer.

Can't wait to see what you will do next . . .

I'm definitely interested in what that analyzer says. I don't believe that 1.1:1 SWR unless that feed line has a matching section in it.

Doc, it has a 1/4ƛ 75 Ohm matching section on it.

The X is not a resonant length at these frequencies.

Robb, IMO it looks like the wire ends of the metal X supports are about 40% PVC and that should allow this one to work OK.

Homer is this laying down flat? If so, how do you think that affect polarity? Is the one in the attic laying down? How do those two compare in performance?
