The broken antenna doesn’t really show up on VHF comms but you get a nice blind spot on the VOR or LOC, as described in the link in post #1.
If WilliamF can’t find his, I may still have the rod which came out of the brass bush shown in the above pic.

Many thanks. I’ll get my info to you.

New and old Nav/Com at the moment. IFD550 and KX155. IFD440 going in at the end of the year.
I think I have two VOR whiskers. Pretty sure of it in fact. They should thread in, or you could tap it.
I’ll post them to you FOC.
Make an adaptor plate and fit a Comant CI215 or perhaps a CI159C2 instead. Then get rid of the balun from the co-ax and terminate with a BNC instead of the ring terminals.
You will probably need to fit a new splitter to derive the separate glideslope signal as your current antenna has separate elements for these. This will depend on what nav receivers you have – the GTN and GNC from Garmin have the splitter built-in.
The picture shows a broken VOR antenna from a TB20.
Has anybody got any suggestions for a repair to the broken fibreglass rod (with a wire running through it).
Or a means of constructing new rods, maybe in stainless steel.
This part is no longer available from the manufacturer.
Update: I bought the last one of these in 2014. No more Socata availability after that.
Certainly one can use a CI-507 (etc) splitter to split out the VOR/LOC and the GS signals, and I reckon there are a number of TB aircraft flying with broken GS antennae and with a splitter quietly fitted…
But that doesn’t solve the problem, and actually the longer antennae are more likely to break anyway.
Usualy the VOR antenna is used for both VORLOC & GS via a diplexer, Garmin do this inside the GTN650 and use a splitter if you have two boxes to feed from one antenna.
As Traditional the French use a French solution to the problem and no doubt charge a premium for doing so, fortunatly in the last year or so Robin have got the message about fitting French parts and are starting to use a lot more standard American parts. For some of these they are producing SB’s to allow the parts to be retrofitted.
I agree (the various avionics shops must be doing some sort of replacement) but find me one that fits 
I did look but didn’t find anything that looked similar. Maybe these things are sold (in aviation) as complete assemblies? That is how Socata sold them.
I have just bought the very last ever set from Socata.
