I had a 9-50 up for years with a KT34A on top. Moved it once to a new
location. Tower was okay but won't last "forever" as the bolt holes at
the leg junctions elongate over time and sections become useless
Same experience here. I had two aluminum towers, one from Heights and one
from Universal. Both developed "eggholes". I also found and sold several
aluminum towers with the same problems.
Past opinion on this reflector was "do not drill out the eggholes and
replace them with larger bolts". The solution to counter the egghole
was to guy these usually self supporting towers. That was also a thumbs down
on this reflector.
One other caveat...be careful how tight you tighten the bolts on the
aluminum tower. If you tighten them like you would normally tighten Rohn
will be very challenging to get them apart since the aluminum bends together.
This, coupled with oxidation from the joint makes taking them apart "fun".
You can't hammer and beat the sections apart like Rohn 45/55. If you do,
plan on making a trip to the local welder. Or worse, to your local scrap
As always, YMMV.
