GS antenna coupler

[[email protected]]

I currently have a single Nav radio w/GS connected to a nav antenna via
a triplex coupler with 2 Nav and one GS output, and I have one Nav
output from the coupler that is not being used now.

I want to add another Nav radio w/GS to my plane. I can use the extra
Nav output from my existing coupler for the new Nav radio, but I need
an additional GS output for the new GS receiver. I know there are
quaplex couplers with 2 Nav outputs & 2 GS outputs, but they are
expensive. Questions:

Can I use a GS duplex coupler connects to my single GS output of the
existing triplex coupler to get 2 GS outputs?

Is there any plan available for a home made GS coupler?

Why in heaven's name do you want TWO glideslope receivers? Just like the
man with two watches who never really knows what time it is, you will never
really know which one is telling the truth.

Try this one again in English without all the abbrvtns.

Cat 2 ILS?

But seriously, some ILS/LOC approaches use VOR radials to identify
the fixes. If both nav receivers have glideslope, then it doesn't
matter which one you use to tune which navaid.

Because your two-watch supposition is based on the fact that you'd have
no indication that one ILS system is non-functional. The incremental
cost to put a second GS in my plane was next to nothing. If the
Garmin GNS80 goes dead or the HSI it feeds whacks out, I still have
a relatively plane jane NAV/COM feeding a traditional CDI indicator.
