I don't think I have ever seen just hoisting grips used to support a cable
on a tower, in this area it's either UV tyraps, band-its, wire ties, or
hanger kits. The recommended cable spacing is 3' per hanger.

FWIW, I use the Cablewave one's and they are $17.10 for a package of 10
through Tessco.

Best way is to use the hanger kits, although it's also the most expensive,
it will increase the longevity of the cable due to flexing/ice buildup/etc.
