it is better oriented horizontal for NAV because the NAV signal is horizontally polarised, comm is vertically polarised hence the vertical 1/2 wave antenna in the fin.

Now, the question remains, is it better to orient the antenna horizontally for NAV, compared to vertically for COM?

BOB Archer makes a whole set of antennas for glass aircraft. Aircraft Spruce sells them. I put my VOR antenna in the wing. I can get a good signal fifty to sixty miles away.

I hope you have not closed out your wing. If you have then you could built a Baluná antenna.
