I just installed the com antenna.  I placed the antenna about 8 inches forward of the back of the luggage area on the top skin.   This skin is very flimsy at this point.    What have others done?   My gut says it's too flimsy and should have a stiffener added.

Dan,



I added a 5" x 8" x .040 doubler under the skin.

Did you include the two crimped L angles that arch between the two upper

front-to-rear L stiffeners? See pages 8-10 of this part of the photo

I was not happy with my original location also.  I ended up moving it and 

putting in a stiffener.  You can check it out here.

I MOUNTED MY AS FAR AFT IN THE BAGGAGE AREA AND ADDED A .040 PLATE TO IT AND CURVED IT TO MATCH.  I ALSO ENDED UP PUTTING A ACCESS DOOR UNDER THE FUSELAGE, AND WITH THAT I WOULD HAVE PUT THE ANTENNAE OVER THAT AND NOT IN THE BAGGAGE AREA.  STILL WORKS FINE

Craig,

Oops :(  Thanks for reminding me.   I knew about it at one point.   Anyway I think I'll combine the crimped antenna support and a doubler under the skin like some others have done.  Thanks for setting me straight.

Luckily it wasn't riveted yet.

Thank you to the others that replied too.

Dan
