What rule of thumb? Each coax has a minimum bend radius specification,
both repeatable and non repeatable. LMR-400 has a very small, non
repeatable bend radius.
This one has been handling the legal limit for quite a while and it was
accidentally "proof tested" once. It will definitely handle the legal
limit with room to spare.
