I just uploaded some photos of my foldup portable transmitting type
loop in the photo section in the folder called N4ZOU. Note the
strange motor drive setup! I wanted to keep the amount of metal to a
minimum inside the loop so I used two 4 foot by 3/8 inch
fiberglass "electric fence post" rods and used copper tubing
compression fittings to join them in the middle. It also balances the
loop so it's not hard to pick it up and set it in the tripod mount.
The loop uses an Armstrong rotor design....Mason string!

I just joined the group. I have built a Magloop for 20 and 40
meters
and it's great for taking camping! It is made from 20 feet of old
RG-
8 coax which I am using the shield for the element and an old
split
stator capacitor with a motor drive for tuning. Holding the motor
drive, capacitor, and RG-8 coax loop element are two 8 feet long
fiberglass round rods with a 3/8 inch bold running through both
in
the middle to form a X shape which folds for transport. No more
slinging wire and rope in trees that might not be available and
only
take 5 minutes to setup and start operating! No tuner required so
less stuff to take along. It outperforms mobile HF antennas and
low
hanging dipoles. I am thinking about improving the design by
making
the element of 3/4 inch copper plumbing pipe and make the shape
to
just fit the inside of my truck bed for transport. The copper
tubing
would work much better than the coax.
Hi
Very interesting loop. If you can send photo in the photo section,
that would be great.
