Ok.  Well at that distance I am maintaining a stable connection with a 13Dbi Omni currently, so I think it's a pretty good bet that the horn will work fine.

I tried to find info on distance limitations for both the 60 and 90deg horn's but wasn't able to find any.  My 2 longest links are 4.14Km and 3.74Km.  Everything else is within 2Km.  Is this doable with the horns?  Both 90 and 60?

Ubiquiti AC Prism's,

Combination of NB16, NB19, and LB23's for CPE's.

I should have added.  I am not providing service past 5Km.  So the signal does not need to hit horizon.

Hello, I'm trying to see what downtilt I need to have for the 6 60deg horns that I will be installing on a water tower in my home town.  The Rail they are mounted on is approx 135 feet high and the closest possible customer is approx 80 feet away.  Any suggestions would be greatly appreciated.

Ok.  Thanks for the help

All AP's will be RocketAC5-PRISM's, CPE's are a mix of LBE-AC5-23 Litebeam, NBE-AC5-16 NanoBeam, and NBE-AC5-19 Nanobeam.  Red Circle is the 5Km service limitation. Actual hope is to keep it to 3.5 to 4 Km or less. 

Thanks for the help.  I've attached all the photos I think you'll need.  New startup project so open to any/all suggestions.

All AP antennas will be mounted on the walk way surrounding the tank of the water tower at approx 135ft.

Also was considering using the Ultra Horn for a 5Ghz AirFiber 5x link at 17.11Km clear LOS.  But can't find it for purchase anywhere.

I saw in another post that one of the administrators was willing to help calculate downtilt on your Symmetrical Horn Antenna.  I was hoping to get some help with this as well.

All CPE's will be within 5Km of Tower location.

I can attach overhead pictures of the area if needed.
