Hybrids  may be mounted on bare wall surfaces; transceivers must 
follow mounting guidlines listed in IM 02-0245. Typical back board 
mounting is illustrated in Figures 5 and 6. Hybrids are passive devices 
and may be mounted in enclosed spaces; leave room for cabling and test 
access. Ceiling mounting of hybrids should include custom brackets 
with nut and bolt fasteners with IDS clips (see IM 02-0245) to support 
the hybrid and cables. Supporting hybrids on ceilings with common dry 
wall anchors is not recommended. The hybrid requires a mounting kit 
consisting of:

-  2.5" x # 10 wood screws
- washers 1/2" outside diameter
- a hole drilling template

Note: The Hybrid(s) should be mounted to permit the RF cables to enter 

and leave with out excessive bending and stress on connectors.
