Hi Oli
Construction method of course depends on the size/freq of the thing. In
some cases you can use plumping or electrical conduit fittings . I have
also seen muffler clamps used but be careful not to weaken the element
too much my drilling. Possibly a muffler clamp bolted to some flat bar
which is then attached to the elements with hose clamps. Watch out for
dissimilar metal corrosion though..
These loops can also be hung from trees. You may even be able to use PVC
pipe as supports if the frequency isn't too low..
I had a double delta some years ago that had two elements arrange
bow-tie like off opposite sides of the boom. This reduced the torque
stress somewhat as the element from one side mechanically continued to
the other.

Hi all,
I'am looking for a maximum informations about delta loop antennas.
First of all, I found a lot of interesting documents with Antenna Searh
http://www.les-antennes.fr/index.php...oop+calculator
that can help me, but I don't find any document who explain what is the
best mechanical technics to fixed elements to the boom.
Best regards
