One wishes to leave slack in one's outdoor cables in case we
reposition things one day, or a typhoon.

We hear it is a big no-no to concentrate this slack all into a loop
several turns thick, creating an inductance (except for the one loop
right below one's 2-meter GP antenna.)

OK, we will distribute this slack evenly along the 80 meter run of
RG-213, nice if a tree gets blown over on it.

But too much slack looks goofy snaking along the nylon support cord.
How much slack is right? And in what formation shall we distribute it?


I would think that the best thing you can do is evaluate your
possibilities. Look over your site and figure out your risks and how
the coax may be affected if a wind blows or a tree sways or a limb
falls. I don't believe that coiled coax will hurt your signal, but it
will be twisted and/or kinked if a limb falls on it or it is otherwise
stretched out due to a disaster.

One thing I learned the hard way is to create a break-point in the
line where if something grabs the coax and keeps going with it, it
releases from the radio it is attached to. In my case, I have a board
through which the coax runs but the radio can't pass through. IF the
wire is pulled from the back, it will break loose from the connector
before taking my rig with it.

Good luck.
