  The Apollo (Garmin) SL-30 installation manual says the SL-30 receiver has
  sufficient receiver sensitivity to pick up a good glideslope signal using
  only a standard NAV antenna.  The SL-30 only has a single NAV antenna input
  (no separate Glideslope input jack) and they advise against combining
  signals from separate NAV and Glideslope antennas to create a composite
  signal at the NAV input.  

  One person said that most new Velocity's no longer even install a separate
  Glideslope antenna because of the ability of the newer receivers to derive a
  good Glideslope signal from the NAV antenna input.  This would also simplify
  our desire to shoot ILS approaches with either the SL-30 or CNX80, even
  though we only put one Glideslope antenna into the airplane.

  My question is:  has anyone had success getting strong Glideslope
  performance on an SL-30 (or CNX80) using only the standard Velocity NAV
  antenna input?  

  Thanks,
