Fixing OverTheAir TV Reception

Noticed a decrease in the number of over the air TV stations we were receiving in the past year. Ran a scan last month and received none, zero, TV stations.
Ordered a Sensar IV antenna to replace our original, and, got some new heavy duty coax wire (about 6 ft). Replaced the antenna which was very easy. Coax was difficult. Disconnected at roof connection and duct taped new coax to old coax to pull up through the aluminum tube. Couldn't use a connector, too long to fit into hole. Eventually got the coax through, hooked up to antenna, and tightly sealed the connection going into the roof with gray silicone gasket sealer. Oh, also heat shrinked both connections, roof and antenna to prevent corrosion.
What a difference! Scan revealed 35 channels!! Old coax was thin and pitted.
If you're having reception problems, go with Sensar IV and quality coax. You won't be disappointed!

Just six feet of almost any line will have negligible loss. If he couldn't fit standard 75 ohm line through with an F connector on it there's no way RG-11 would fit anyway.

I would agree. However, I was having a very bad day trouble shooting and decided what the hell, it must be the coax and changed it (it was me that was the issue). Just tying to make a point there is things out in the world that most would not consider.

Fred, Wally, & Mark,
Got to admit it was the original equipment and we got it, Fleetwood Southwind 32V, new, 20 years ago. Had roof R2 six years ago and Camping World said it was all good. Maybe it just degraded quickly? Thanks for the info. Coax is crucial and threading it through the tube was a challenge. Feel dumb for not doing anything earlier. Sensar IV is outstanding.
