I need to add a second AP on a tower and need help.
How far apart must the 90 degree sector antenna be placed?
Can they be the same polarity?
Can I run LMR-400 to them about 70ft?
Anything else I should consider?
Thanx

I have several sites that have multiple 900MHz APs using 10MHz
channels. Obviously the more separation the better, but I have a couple
of sites were the separation about 18". Both vertical polarity. I have
not noticed any issues.
I run 900MHz on LMR400 up to 100'. Over that I use LMR600. I
Before smartmeters (BC) we had 3 integrated 900's on the same tower at
906, 914, and 930 without issue.
It's really about your available spectrum. You need a minimum of 9MHz
spacing.
75'of cable should not be a problem other than loss is loss. I would
put the AP on the back of the antenna
Was that even legal? I thought the 900 MHz spectrum that we are
allowed was 902-928.
