I'm thinking of re-doing the antenna farm; moving my Imax from the chimney mount to tower #1 replacing my 2 element quad. The 4 element flatsider on tower #2 will be replaced with something large with switchable polarity, something like a 6 or 8 element long boom design. My question for the antenna guys here: has anyone tried adding directors to a PDL2? I've got a ton of parts here: PDL pcs., 'Raker pcs., Wilson/Maco pcs., as well as all the tubing I'd need. I have enough large diameter boom to go to about 48 feet, if I choose to. I can go quad, yagi, or hybrid. I'm thinking of adding onto the PDL design. Any input?
