3 . 2 ANTENNA INSTALLATION
The GA 56 Antenna outline and footprint dimensions are shown in Figures 3-1 and
3-2.
A. Using the backing plate as a template, mark the location of the mounting holes and
the through hole for coax cable. Drill or punch the holes.
B. The antenna installation must provide adequate support for the antenna considering
a maximum drag load of 5 lbs. for the GA 56 antennas (at subsonic speed). Install
a doubler plate to reinforce thin skinned aircraft. Observe guidelines for
acceptable installation practices as outlined in AC 43.13-2A.
C. Seal the antenna and gasket to the fuselage using a good quality electrical grade
sealant. Use caution to insure that the antenna connector is not contaminated
