bend like that? I?m imagining there?s quite a nasty impedance bump going on
here, not to mention the potential for physical damage to the dielectric in
the heat and cold, etc.
There are a couple of schemes for a larger bending radius - I think
Chris, KF7P has one. I've installed dozens of crank-ups and guyed towers with
hundreds of feedlines with the same technique of just dropping them over
the edge and I've experienced zero failures that I know of.
The only coax I'd worry about are the ones with foam cores - they can
cold flow over time and cause the aforementioned impedance bump, perhaps
even failure in extreme instances.

Was there a problem with the existing feedlines or are you just
replacing them because they're old? I'm a big proponent of "If it ain't broke,
don't fix it". I don't want to discourage your from spending money but maybe
this is a very discretionary project that has more psychological benefit
than actual operational improvement.
