Yeah, that sounds like a good approach.  Even on a commercial tower, if you 
mount it near another antenna, the tower owner probably won’t even notice you 
snuck another antenna up there without paying more rent.

On the ones that I cannot get good signal I use a bare loco on both sides, one 
pointed up and one pointed down, on a 5MHz channel.  It will usually still get 
them 15Mbps, without sacrificing too much spectrum at the tower.

  Do you have a cabinet or shelter at the bottom of the tower?  I have been 
considering just putting an omni down there, since it rarely works well 
shooting up at the APs.  At grain legs, I have sometimes done a low powered PTP 
link with something like NS5 Locos just for a scale house, maintenance shop, or 
house right at the leg.  Then you can tilt it down.

  I think it’s more than just hearing all the APs, there seem to be problems 
being outside the main lobe of the antenna, plus reflections off tower steel, 
even once you get the signal level to an acceptable point, SNR and modulation 
can be disappointing.

  If you’re convinced the only problem is too strong a signal, you could always 
use an external antenna and an inline coax attenuator.

  Does anyone have any tips for this?

  My only thought process was to do an integrated radio *inside* the office 
building to keep from hearing every AP on the tower.  We've had some issues 
with nearby customers using a Force110/Beam hearing way too much of the tower 
so we moved to Integrated/Nano to solve their problems. 

  I have a business that needs service and it's literally the same address as 
the tower (150 feet up).  It's 60 feet away to the middle of the office but the 
ends are about 120 feet away.
