I sent this link in reply to another similar question a couple of days ago.

Issue is not interference with the SteppIR from the VHF/UHF, but with the
VHF/UHF antennas by the SteppIR. Big advantage of the SteppIR is that it can
"disappear" when the elements are retracted.

whether it's feasible to put up the following: Steppir 3 element
(bottom) 12 element 2m horz beam with UHF 21 element horz beam at same level on
metal cross boom, sitting two feet above LPDA (50-1300 MHz) at the top,
vertically polarized. How much will the the V/UHF antenna setup two feet above
affect the Steppir pattern?? Thanks,Ed NI6SWhittier, CA
