Amadeu, I am using a TH7 and a 402CD. The TH7 is at 132 feet and the
402CD is 8 feet above it on the same mast. It works great! No interaction
detected, at all. 8 feet separation was what Cushcraft recommended, if
I recall correctly. One word of caution. Install a multi-pointed (sharp
lightning rod well above the 402CD or which ever antenna you have at the top.
This will tend to bleed off any charges and/or, if the charge builds up too
rapidly to bleed off, it will attract the lightning to it rather than the tip
of an element (on the 402CD) as it did here. It really blew one of my traps and
resulted in a major expense to take it down and repair. Good luck. Rod
