I know what they are and do not need one for pulling thru conduit.  But I
would like a clean way to support the 70' of cable going up to the top of my
DX-70 telescoping tower.

The question is if it is bad form to put more than one cable into the grip.
I understand that the braid will not fully contact any one cable.  The only
reason to consider mor than one per grip is that they seem to cost over $30
each.

Any alternate common method to support cables would be appreciated.  I
suppose good tape on top section is always an option.  Using one RG217, one
rotator cable and one 24 conductor for DB36 control.

A rope wrapped around the cable and itself for a lot of turns (like how you do steps on a rope ladder, or a hangman's noose, it has a name, but I can't remember it). Sort of like a prussik knot.  Choose a rope that will tolerate the environment. It relies on the friction at multiple points.  I found one example:

Also an Icicle hitch looks similar.


Ah, here it is, a pipe hitch.




Thanks.
