Thanks for the quick reply. It sounds like we were on the right track. We hadn't thought about running new cable, but it makes sense especially since we'll be up there anyway!
"Compression fittings" are new to us. Is this what we should order?
Solid Signal Custom Cable with High Quality Solid Signal Connectors
Or do we need to upgrade the cable and have
these connectors substituted as shown on the order page for the cable?
