Does anybody have any suggestions on a good wire supplier? Also, what type of wire is considered the best to use? I am using superior essex Shielded Cat 5 Cable…It works good just a little hard to bend as it has a huge copper shield inside it.

The best is subjective. FWIW we typically buy all of our cable from Tessco (Platinum pricing) which is Belden 1594A for SM installations & 7919A for tower runs.

Belden 1594A for installs here.

Shielded for towers only.
