I have a pair of antennas, 440 and 2 meter LEO typical setup with G-5500 rotor and fiberglass horizontal boom. It is mounted about 18 inches above top of tower on vertical mast. I can probably push it up another 1.5 feet before having to add on to vertical mast.

I would like to also hang a Cushcraft A3S a couple inches above top of tower on mast. I think the back of 2 meter antenna is about 5~6 feet that rotates downward when chasing LEO's.

The reflector on A3S dimension is 7 feet horizontally from mast. I'm wondering if anyone has a setup similar to this and if there are is a negative impact of antenna proximity?

I haven't bought the A3S yet. Want to be fairly comfortable this will work OK before I make the investment in the A3S HF Yagi.
