Hello All: Yeah the plastic hubs will probably need to be replaced with Teflon, Dilrin, or even Fiberglass. Oh and the Cast Aluminum metal Hub is know for having internal cracks and falling apart right out of the box being brand new. But other than that it looks original to me, and rebuildable. I have had new billet 6061T6 Hubs made for replacing the old Hubs. But expensive.
Taking pictures of antennas isn't easy.
Also the PDL II, and Moonraker 4 and 6 element antennas came with cheap 14 gauge wire which would stretch with age. The assemble instructions even say to pre stretch the 14 gauge wire before installation. Suggest using 10 Gauge wire from Amidon, called Thermaleze Coated wire, as the insulation is pretty tough and the 10 Gauge wire will not stretch like the cheap 14 gauge wire supplied with the PDLII antenna.

Please let us know how this all works out for you. good luck.
