Chris,

According the the plans, the VOR antennas are to be built into the bottom of
the wing.  Obviously, not a place where you could cover them with any type
of foil.

I did install my localizer antenna in the cabin floor.  Thanks for the tip.

Best,

Andy

  This note is for those of you that are using the foil tape antennas as
designed by Jim Weir. This is the standard antenna system in the Velocities
and I am sure all of you are using them in some form. I have always been
unhappy with the performance of my VOR antennas mounted on my fuselage floor
and finally wrote to Jim Weir to seek his advice. I wrote:

  "Jim, my question is this. The two VOR antennas in question are mounted on
the floor of the fiberglass fuselage. Over the floor I have I have laid
sound insulation and carpet. The sound insulation has a aluminum foil layer
on each side. Is the foil the probable source of the antenna failure? "

  Jim's response was "Without a doubt!"

  I wonder how many of you have made the same mistake I made in diligently
building your antennas to Jim Weir's plans and then mistakenly covering them
with a foil backed sound insulation. The foil backed sound insulation was
the one recommended by Velocity when I installed my interiors in 2000.

  Hope this helps some of you.
