| Subject: | Antenna doublers |
Are there any guidelines I can use to size doubler panels for the
antenna installations? Can=99t find anything in AC43-13 except
standard rivet spacing. For the bent-whip comm antenna, I have chosen a
location between the passenger left footwell and aft side of the front
spar. Outboard and aft of the F807 bulkhead looks good for the blade
transponder antenna. Both locations seem to be fairly common, but
doubler size will dictate how much surface area I need to provide.

Stan, as I remember it, the one that came with my Garmin Antenna was a
rectangle about =C2=BD- =C2=BE inch wider than the antenna base in all
four directions.

Hi Stan,
Here's a few pics on how and where I mounted mine. Seemed to work well on
Ruby 1.0.

Stan:
While building my RV-7A I searched in vain for guidelines/standards for
doubler panel sizes for antenna installations - even called Vans tech
advice line - couldn't get an answer from them either - at the end of the
day I sized the doublers to a size I thought about right -
a DAR later commented the doublers all looked a bit oversize - better
oversize than undersize I guess - after 37 months and 352 flight hours
they've all stood up beautifully -
Good luck
