I would be more concerned about interaction between the two antennas that
will only be a few (3?)feet apart.

Hi all,

I have a HAM IV rotor here...I see in the manual the maximum wind load area
is 15 sq ft installed inside the tower.

I have a HD spiderbeam for 10, 15 and 20m...The spiderbeam wind load area is
3,5 sq ft.

I want to know if I can install a 2 element 40m antenna few feet below the
spiderbeam without broken the HAM IV ?

What kind of 40m beam I can install to keep the wind load area as low as
possible ?

Thoughts?.

Thanks,

Doug, CO8DM
