Hello Tim,
IÂm having an Optibeam OB10-3W with a 40 meters rotatable dipole at 4Â over 
it. AinÂt got any problem so far. Neither any degradation on lobes or 
changes on SWR has been appreciated here. FB on yagi is better than 
advertised on the manuals and the dipole has been one of my best purchases 
(regarding antennas). On the other hand, I had a wire dipole for 40 and 80 
meters located 15Â under the rotatable dipole and I noticed some changes on 
SWR when the rotatable was placed parallel to the wire dipole. There were 
some interaction among them thatÂs what I finally dismounted the wire 
antenna and put a long wire for 80. YouÂre going to set up a good 
installation though. Good luck. 73s!
