Restoring a working antique dish to full functionality..

Non magnetic CH...
Been taking a look here https://carbonfibreprofiles.com/products/grp-rods
for £30 I could replace all 3 IF they were a metre long.
Sadly not the case as they are 41.5 inches (105.41cm)
I cant order custom lengths so would have to go up a size to 2m which at almost £19 each (16.2mm) diameter is both wasteful and expensive.
I havent even looked into shipping costs.
If anyone has some glass fibre rods around 16mm diameter and longer than 106 cm you have a buyer waiting.

Glass fire rods bend, but you said these are absolutely rigid.
It might be there is an aluminium centre (which would not be the antenna type unless for portable useage)

OK, VS, I see you want to go 16mm glass feedarms. Then take 3x1m, drill 5mm holes from at the ends and make internal M6 thread in those holes. Then take pieces of M6 threaded rods and fix them in the feedarms. On the attached picture I made a model to better understand the idea. If you get issues with the internal M6 thread, later you can enlarge the holes and thread M8 inside. View attachment 171089

Thanks for the suggestion Rima.
I've found a way to contact CarbonFibreProfiles by email and have sent this to them.
I'll wait to see what response I get if, if any before making any decisions.

Hello
I think maybe you could help me.
I am trying to restore a 1.8m satellite dish made in the 70s.
I only have one good feed support arm ...two if you include a slightly damaged one.
made from glass fibre.
16.2mm diameter would be fine for this but the lengths you sell are close at 1 mtre...but I need 44.5 inches (105.4cm) thus the 1 mtre lengths are too short and the next size up 2m are far too long.
Also this would make the cost of restoring very expensive.
My questions
Could you provide 3 glass fibre tripod arms of the required length ?
Cost is an issue so if you can supply them...an idea of total cost including shipping to me would be very much appreciated.
I am in Manchester M27
I appreciate this is not a from stock request...and a one time order.
Many thanks for reading.

I suspect these would shatter long before the showed any sign of bending CH...which is what happened to one of them.
Maybe there is something structural added to the resin during manufacture that makes them so dense and rigid....like a metal powder ?
I do think that 16.2mm diameter even without anything added would provide sufficient rigidity ..in that both the base and the apex are set into cast aluminium.
If I can get replacements cheap enough ..its gotta be worth a punt.
