I recommend the fuselage probe. Ten dollars worth of parts and you're
good to go.

See Nicks and Johnson for the original idea and its refinement. This
article is pretty clear about it:

Also, see Sebald for an alternative installation that combines TE
probe and radio antenna:

Thanks, Bob K.

Bob,

I like the idea of incorporating the Radio Antenna and TE Probe. Do
you still have some of the parts, as said in the article?

This system was designed for a metal sailplane. You will need to create a
ground plane inside the fuselage of your Cherokee. Four 22 inch copper wire
radials should do the trick.
