[TowerTalk] Antenna Interaction

[Edward Sylvester]

Due to only having one tower and a 10' mast, I would like to see 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
