Don't know what is used in the 641 but the interconnect length for the WP-642 set up for N connectors is 12 3/8 inches for the 2 meter band.
I don't think Wacom used RG-223U. Their UHF duplexers were supplied with RG-142 and the VHF cans used a cable which was labeled: "Modified RG-214 Double Shielded". They felt that using silver plated shields was an unnecessary expense that didn't provide any improvement in the cable characteristics. Their "special" cable is double shielded but both shields are unplated copper and are terminated with a captive contact UG-1185A/U with a gold plated pin. I've never experienced any shield noise flexing the Wacom interconnects but others aboard have reported broadband noise generated by unplated shields and are insistent on using a MilSpec RG-214 cable for this purpose. It's not cheap cable, but considering how little you will need for bottle interconnects MILSpec RG-214 would probably be the way to go. In a message dated 2/21/2007 2:30:23 P.M.

Does anyone have a WP-641 that they could take the measurements from? I am also in need of the type of cable used. I think Wacom used RG-223/U.
