I'm trying to figure out what I need.
My panel will have a Garmin 430W nav/com and an SL-30 nav/com.
I have a "cat's-whisker" VOR/ILS/GS antenna at the top of the vertical stabilzer.
I've read quite a few threads here about nav antenna wiring, but couldn't find anything that specifically addressed the way the signal must be fed with my setup, and the need for triplexer and/or duplexer splitters.
Very simply, all I want to do is to use the single nav antenna's signals (VOR, ILS, and GS) for both nav radios, without any kind of selector switch.
There are all kinds of splitters available -- for instance, Aircraft Spruce's P/N AV-571 is a VHF triplexer that allows the use of a VOR/ILS/GS antenna by 2 nav radios plus one GS receiver. Great, but I want the GS signal to go to both receivers. Do either the 430 or the SL-30 have a GS diplexer built in? If not, can I split the signal again, with a second splitter, without losing a bunch of signal strength? Does it matter that much?
I'm a bit confused here. Anybody wanna help me sort this out? Thanks!
