I have found very little in the way of GS antennas on the market. I am

looking for a solution for a fiberglass airplane. Perhaps one of you

have crossed this path and found a good solution? I already have a built

in VOR antenna in the wing, two COM dipole antennas attached internally

to the fuselage, a transponder antenna through the floor and a beacon

copper strip antenna on the floor. I would like to avoid the cat whisker

arrangement found throughout GA aircraft.

Why not use a splitter for your VOR antenna then you don't need a

separate antenna or cable

Frank,

	I thought about doing just that, however I only have one VOR

antenna and two NAV radios. I have seen a splitter which will allow for

both but I am hesitant to use it for fear of signal degradation.

Good Evening longg,

  

 I think you will find that at least ninety percent of the certified  airplanes that have had a radio installation in the last twenty years will use  one set of blades or a V antenna to feed two nav radios and two Glide Slope  receivers. As 'Lectric Bob has noted, at the ranges we use, a wet string would  probably be adequate.   

A set of blades is elegant and work very well, but even the  cheapest V antenna when spilt with a four way splitter will give every bit of  signal any modern receiver can use.

  

 Happy  Skies,

I have an Archer wingtip VOR antenna with a splitter and it works very

well..Could you use a second wingtip job and split that signal instead,

i.e two antennas and two splitters?



I'm not sure how the signal would degrade if you used a single antenna

to two radios?
