As a part of the  installation of the landing light package in the wingtip, I put in a 6-inch  strip of aluminum foil which came in the kit as a heat shield.

  

     I'm now  contemplating (obsessing?) over the location for the VOR antenna.  Will the  strip of aluminum foil make a substancial difference in the reception capability  of a wingtip antenna?

  

     All comments will be  appreciated -- and Merry Christmas to all!

    EVERY conductor located within inches of ANY antenna will have

    SOME effect. If we were blessed with access to some of the very

    sophisticated antenna modeling and performance predicting software,

    we could probably quantity the degree to which your contemplated

    configuration is affected.



    No antenna mounted on an airframe is "perfect" and many suffer

    from deep performance nulls on some look-axis . . . yet most

    antennas are deemed "satisfactory" by users who fly them.



    Anyone's non-quantified predictions attempting to answer

    your question might just as well be offered by throwing darts

    at the whole range of possible answers.



    Give it a try and if you perceive some degraded performance,

    you're in a position to do the repeatable experiment where

    the foil is removed and the antenna re-evaluated in the same

    operating conditions.
