Keep in mind that the glidescope information is transmitted on a
frequency that is very different than the VOR/LOC frequencies. It is
recommended to use a splitter and a separate antenna for reception of
the glidescope info. You might get away with just a VOR/LOC antenna, but
this depends on the properties of the antenna. The antenna is deeply out
of tune on the glidescope frequency, and in general, antenna's that have
been reduced in size, have more problems with this and some are even
effectively shorting out the glidescope frequencies.
My dipole setup probably works better for this than any commercially
available antenna.
