Extending a HSS cable


Link Posted 08/08/2018 - 18:16
I've just extended my curly (annoying) HSS cable using Cat5 network cable.
My guess is there must be a limit to the length I can go due to voltage drop and speeds etc. but I went with the entire length - about 10m I think.
It didn't work. It fires as a normal flash but won't fire above sync speed (as if it isn't a HSS flash).
Anybody know how long a HSS cable can be?

Yep, same happened here when I tried 5 metres. Now using a 2 metre cable made from a length of overall screened 6 core. PTTL and HSS are good at this length for me.

Just to update this; I shortened the cat5e cable to about 3 metres and it worked sometimes, but was unreliable.
This type of cable is not ideal as I am leaving all but one of the pairs twisted (less resistance) and using the last pair untwisted, so really that's the weak link and essentially it's behaving like it's all single cores.
I'll buy some more suitable cable as above, and try again. Watch this space...
