2.5?
I've been trying to figure out the >> Antenna Horizontal Isolation Calculator
https://www.commscope.com/calculators/qhisolation.aspx
Where it's at...
Aerial 1: 4db car vertical, mounted vertical, 4 meters (approx) thin coax, cheap uhf plastic mount on metal gutter mount, mounted on metal house gutter.
Aerial 2: 4db car vertical, mounted vertical, with 4 meters (approx) thin coax into 8 meters LMR400 (barrel connector joined) mounted on a cheap uhf plastic mount, on 7 meter alloy pole metal earthed-braced on metal gutter..
Dodgy parts, dodgy results
I'd separate the aerials by 10+ meters (I have plenty of coax) but I'm not sure that would even work with all that wave length 'n lobe stuff + dodgy variables with the dodgy components.
Did you check the swr on both aerials?
By the time it gets working :vasfag: would have sent the fuzz over to rip it all down.
