My new (to me) roof tower has a solid (i.e., no holes) mounting plate for a Yaesu rotator, which has its control cable coming out the side. I use a TR-44 rotator, so I need to (have a metal shop) cut a hole in the plate for the control cable to run through to the bottom of the rotator. Where can I find a template for the rotor? Thanks in advance, Eric W3DQ Washiongton, DC
