The boom is 3 side square aluminium tubing as used in construction of
Aluminium doors and windows etc..

The elements are attached to the boom but U bolts that are fasened very very
tightly. It's up for about 6 months now and I check it every month and there
isn't any loose ness at all.

Cheers,

The answer would be probably, but you really need to give more information
such as

o frequency
o boom diameter and shape
o description of the clamp

Draw us a picture with words.

Hi all,
I have a uhf yagi uda antenna mounted on the roof I have all the element
(alu welding rods) clamped to a alu- boom except the active elements.
Does this effect the preformance of the antenna in that the reflector
and directors are all connected from an electric point of view?

Cheers,
Xanax.
