We used to loose lot of radios too.

We do following now and it seems to help (loosing less).

At top on the tower:
We put all AP on stand off (MTOW-p), then we have grounding block mounted on 
the stand off at same level as AP, then less then 2 feet of cable going from 
grounding block to AP. All shielded cable and grounded to tower.

We have lost few ground block on tower but it seems to save radios.

Some ideas came from orthogone system product and their grounding guide lines.

At the bottom 
 
Shielded cable going to grounding block and then to equipments.
