Mounting a Radio

Ken · Post by **Ken** » Sat Feb 18, 2012 10:23 am

Gentlemen

The easiest way to mount the rear of a radio tray would be a bracket on
each side riveted to the firewall. I am wondering if that is a bad idea
though as any movement of the firewall relative to the instrument panel
would stress the radio tray and maybe the expensive radio??

Other thoughts are that perhaps a little shelf back there for the radio
tray to just sit on (but not be bolted to) would be better.

Or bolts that go into a rubber mounted nut plate or vibration isolator
of some kind to allow a bit of movement.

Any thoughts??

Gee Ken, I'll have to have a look up under a couple of panels.....must be
the alum dust as I can't remember how I did it..but think I took side straps
back up to the instrument panel to firewall deck.

Ken, depends whether you are starting your stack high or low. If low, just a
bracket on each side from the 5/8 x 5/8 panel brace tube to the lower radio
tray. Then you can add more radios/transponders on top of this one as it is
already supported. When doing the front mounting area, be sure to use a
couple of angles (3/4 x 3/4 works) from top to bottom of your panel. This
way you can add radios and transponders as needed by simply drilling a
couple mounting holes, clipping on a few clip nuts and you're done (other
than wiring of course!). If mounting the radio high up you can either hang
it from the top panel or brace it with some .063 or similar from those same
5/8 x 5/8 tubes. Harder to add onto though.

Just want to correct that...1/2 x 1/2 angle works...3/4 makes it too far for
the clip nuts to reach the hole.

Thanks Wayne

I have the vertical angles on the panel already. I haven't purchased the
radio but I wanted to get all the mounting brackets in for an icomm
A-200 before I close the top of the panel. It's not going to be fun
working upside down under there! The radio is going in the bottom of the
panel. My square panel brace tube is not in the ideal position (moved
back firewall ;) ) but if radio trays can sit on top of each other then
I think it will do the job. I will see if I can add a triangular brace
from the top of the instrument panel to the outboard rear radio corner
as well.

Actually I wasn't entirely comfortable with that so I cut the bottom
flanges off one then riveted half inch high brackets to the floor and
bolted it all together. Same result - a removeable control tube. Think
the idea came from Brian.
