I believe that coax is a copper clad aluminum center and copper clad aluminum braiding. After releasing PTT there would be a low pitch screech which would sometimes continue activating the repeater for a few seconds. PL-259 is simply the connector, also referred to historically as the UHF connector. The actual cable type should be marked on the jacket of the cable.

The coax on the UT-72 is RG-58A/U which I believe is tinned copper for the braid. Quote Link to comment Share on other sites More sharing options...

But one thing to be aware of is the power attenuation that happens at GMRS frequencies in RG-58A/U. It’s not insignificant as something I wrote recently was corrected.
