The Glide slope frequency is near the third harmonic of the localizer frequency and antennas perform fairly well on odd harmonics, an antenna designed for 108 to 118 MHz will also be useful on 329.3 to 335.0 MHz.
The ground based Glide Slope antenna beams most of the 40 watt signal toward the aircraft which is only about 5 miles away so it does not take much of an antenna to receive the signal.
