Thanks, Doug -
I'll get some RG-6 and do it over. However, the cable run from the toadstool in the alley to the entry point in our home (attic) is well over 80', and it was installed around 1984 by Jones InterCable - the predecessor to Comcast. I'm wondering if that cable also should be replaced -- although we still get 100% good basic cable TV service (we haven't gone to digital as yet).
