As Don said, antennas that are resonant at half-wavelength are also resonant at 3/2, 5/2, etc., wavelengths, so they work well at 330 MHz. The 50 ohm matching network may be off a bit, but, as Don said, the GS is relatively strong. There are 1000ís of flying airplanes with dipoles for 110 MHz up on their tails that also use the same antenna for 330 MHz GS. My SL30 doesnít even have a separate GS antenna input - it expects to use the nav antenna. BTW, I have an Archer in my wingtip, it works fine - vor, loc, and GS.
