"Yes they do" final answer
Can anyone say for sure that both the garmin 430W and SL30 have internal splitters for VOR and Glideslope. In seaching, it appears that some 430s do and even a couple SL 30s.  Can I return my glideslope antennas? |

I know for certain this is true of the SL30--I have a single archer wingtip nav antenna and have no trouble with VOR navigation and ILS.

I just plumbed up the coax for a 430W and a SL30.
SL30 does have the internal splitter. The 430W does not.

Confirmation on what Alton said; SL-30 has a single coax input for the nav side and splits out the GS internally. The GNS-430W has a seperate input for nav and GS so for it you'll either need both a nav and GS antenna or a diplexer (like a Comant CI-507) to split the GS signal out from a nav antenna.

Thanks all. I think I'll go with a diplexer for the 430.

...non-"W" version of the 430 as well.
My IM shows two separate BNC inputs for GS and VOR/LOC co-ax.

An alternative to a splitter (which will cut down your signal strength to the VOR) is a very simple "stripped-wire" Glideslope antenna. Take a piece of Coax, strip off 18" of braid, and mount it in your cowl or on the windshield bow - put a BNC on the other end and connect it to the 430's GS input. Nice strong signal, and the VOR doesn't lose half it's input signal!

That sounds even better. Saves 135 bucks too. Thanks for the tip.

Not quite half

Hi Paul,
The homemade antenna is a great idea and way cheaper than the diplexer. Just so no one gets the wrong idea - the specs claim an insertion loss of 0.5 DB and that would translate to approximately 12% loss in signal level. I'm sure you didn't mean the half literally.
