Radio mounting details
Tie wraps
You can also use tie wraps as a secure but non-permanent means of attaching the radio modem to a
surface. Typically, each tie wrap passes through a hole drilled into the board’s surface on either side
of the radio modem. This enables the radio to be attached to a shell, a PCB, or other mounting
surface.
Warning: If you use tie wraps, make sure that the surface beneath the radio modem is flat. Otherwise, the
mounting surface can push up on the bottom surface of the radio case, and the tie wraps, when tightened, can
push down on the edge of the radio case. This pressure can cause the radio modem’s metal case to flex upward
and short circuit components inside the radio.
