Main concern is when the tower is being tilted. Put too much extra
weight at a large 15' moment arm and you might be in a grey area.
I don't know if it is OK or not. However, I had an EZway tower with a
4 element Gem quad on it, 5' above the top of the tower. That would
be about 30 pounds x 5' =150ft/lbs of added moment for tilting. I
also had a Ham 1v mounted at the top inside of the tower.
You are adding the weight of the mast + 15'x8 pounds = 120 ft pounds.
A steel mast could be quite heavy. But you don't have a rotor.
Perhaps using an aluminium mast would eliminate concerns.
