Is the EDX-2 control-cable expandable ?
Yes, but please use heavy-gauged wire (at least 20-18 gauge than the original cable) to avoid the loss of the driving current and it is not recommended expanding it to over 50 feet; You may find a good rotator cable as the replacement. Before unscrewing the connection inside EDX-2 for the replacement of the cable, note the color configuration of the cable/connector (There are 2 versions for the color configuration). For the input coax-cable, use appropriate 50-ohm cable with PL connector.
