I read somewhere that it was recommended to leave a few feet between  

NAV/COM antennas and GPS antennas.

This would mean that a typical Cessna doesn't meet the  

recommendations, since many have a NAV/COM on each side of the cabin  

roof and the GPS antenna in between.

Is this an important recommendation I should attempt to achieve ?

I could put the NAV/COM antennas outboard of the high wing fuel tanks,  

giving me about 12 feet between them, but at a cost of longer cables  

and future difficulty if they ever need replacement.

What is the best positioning for these antennas on a high wing all  

aluminmum aircraft ?

Thanks,

Jeff Page

   Every supplier of every product has his/her

   list of fondest wishes for pristine installation

   maintenance and operation of their particular

   product. It's often difficult to know

   exactly where each item falls with respect to

   absolute requirements, risk mitigation, and

   "gee, wouldn't this be nice."



   In practice, planting the antenna farm on top

   of high wing airplane cabins has proven practical . . .

   even tho spacing was not compliant with

   the fondest wishes of all suppliers involved.



   Give it a try.
