I will be using a 15 ft reinforced double-wall 2" mast on top of my 72 ft US Tower. With a T2X turning it, I will have about 11 feet of the mast extending out of the tower. I will be mounting a TH11

Hi Dick, I am going thru the same thing and am putting a Rotatable dipole for 40 over a TH11. I have been told by various folks that 8 foot separation is adequate and others say a minimum of 10 feet.

Sounds good to me. I've seen them stacked with as little as 6-7 feet between them. The biggest thing you'll see as they get closer together is that the SWR's will go up they get closer. I don't have

I agree. Don't put the boom support under the boom. I did it for 2 years, and when I took it down I found serious stress cracking at the swaged end of the strut. If you put the strut over the boom, y

Watch out...W6QHS (now W6NL) says not to do this, even though he once advocated it. Instead, beef up the boom, use the HiGain boom/mast clamps and eliminate the boom trusses altogether...All per Dave
