Resurrecting an old thread here. I'm working on building a new panel with a
GNS 430 (needs separate VOR and GS inputs) and a SL-30 (internal diplexer so
needs GS and VOR on same coax). My question is, with the referenced
splitters/couplers, does the glideslope freq range get stripped off of the
VOR outputs? (Real question, if I use the CI-505, will my SL-30 see the GS
freqs from one of the VOR outputs?) I understand I'm getting less energy to
the receivers, but I want to give a single antenna a try before I add a
second during this retrofit.

Thanks much,

John

This exchange might be helpful...

No. It only passes VOR frequencies. Use our new CI 5120 instead.

I have the same setup, GNS430 and SL30. I attached a BNC T-connector directly to the VOR/GS input connection on the splitter. Connected VOR/GS antenna cable to 1 branch of the T, and ran a short cable to the SL30 from the other branch of the T. That way, SL30 gets both VOR and GS, while the 430 gets the split outputs from the splitter. I don't know how much signal loss I have, but it has worked well for almost 2 years. The SL30 does pick up the glideslope a bit sooner than the 430. I haven't noticed a consistent difference in VOR range between the two.

LOL, it's always the simple solutions that evade me... Thanks much...
