Just to add, RG402 is easy to find in E-Bay or Aliexpress.
Will give a try and build one more choke (for 10, 15 and 20m) with RG402.
Hopefully nothing wrong happens...

Asunto: Re: [TowerTalk] RG402 for Choke/Balun
I have no experience with RG402. It appears to be a little smaller
and it has a steel conductor. What RF properties are better?

Hi all,
I normally use RG400 for chokes on FT240 toroids.
Recently I've tryed RG402 semi-rigid coax cable, the "blue one".
RF properties are quite similar, in fact RG402 seems to be a bit
better than RG400.
Because RG402 is semi-rigid, is much easier to make tight turns on the
toroids, easier to work with.
After some months using it, HF bands legal limit amp, I can't see any issue.
Just wondering if I am missing anything, or if someone else have tried
the RG402 coax.
Thanks
