Winegard TV antenna cable replacement.

Has anyone replaced the cable from their crank up tv antenna? The cable that goes from the antenna I through the roof seems to be bad. How hard is it to replace it with a new cable?

It might just be the connector. I replaced my connector at my crank up antenna. Works great now, I get 22 OTA channels here in the Kansas City area.

I have no continuity from one end to the other.

Are you sure you are measuring the correct cable? It is real hard to break a coax cable. If it is bad, it depends how it is run, it might just be as easy as connecting a new coax using a barrel connection and pulling the new coax in. On the other hand it could be a nightmare to run a new coax.

Yes, I'm sure I'm measuring the right one. Checked and double checked. No continuity.

Is that no continuity on both the core and braid? How did you verify you have the right cable?

No continuity on both. First time, I read the labels on the power injector. Tested the one labeled antenna. Second time, I verified continuity on the others, 2nd tv, and cable. They are good. Only one that won't check out is the one from the antenna.

replacing that cable is almost impossible on mine. the cable is either bundled on to roof beams or immersed into the roof foam between the layers. i tried to pull it but to no avail.

in your case, you can connect the center and shield at one end (short the two), go measure the resistance at the other end. if you get 0 ohm, the coax is good. if you get an infinite, you would probsbly need to get a new cable floating on top of roof, or going through the cabinets inside...

Done that. That is how I know it is bad. Before I got tired of the corporate world and became a medic, I was an electrical engineer. Very disappointing, I thought bring an electrical engineer meant I could drive an electrical train....

Had mine go in a 2004 Phaeton. They run one piece of coax from the antenna to a connector at the base of the antenna, just under the goop and the antenna base itself. Then another piece goes from there into the coach. My problem was at that connector on the cable that goes up the mast. Easy to change after I found that connection. The one from there to the inside would be impossible w/o making a new hole as the coax is foame in

I replaced both the outside coax from the roof to the antenna top & also the coax cable in the roof down to the cabinet connection. On my 99 Itasca there was a connection buried just below the surface. I would only replace the antenna/external coax if doing it again. I had a time "fishing" a wire thru the foam
roof but eventually got it. Boy did it make a difference, I had lost almost all reception.Click image for larger version

On the Winegard, as you probably know, you should get 12v dc on the cable at the antenna. On two previous mhs I found the connection just below the mounting plate had corroded. I removed the mounting plate, replaced the connections just below the plate—they seem to get moisture and corrode after a time. I also replaced the cable from the connection through the lift to the head. The key is finding some uv resistant cable. It’s not a really big job and in my case it solved the problem. On my present 2001 Winnebago which I recently purchased, I updated the antenna and decided to go ahead and replace the cable. When I removed the mounting plate, the builders had looped the cable under the mounting plate and mashed the cable between the mounting plate and the roof. It wasn’t causing trouble, but surely would sooner rather than later.

Generally the cable "Through the roof" is in 3 parts

1:Cable TO the roof
2:Bulkhead connector THROUGH the roof
3:Cable to the antenna

The 3rd part often fails (Due to effects of sunlight) and needs replacement, In fact it is time for me to consider doing that

The Second part: I have heard of at least 2 failures (Seen one personally)

The first part: almost never fails since it is not exposed to sun or weather.

This one is in two parts. One From the winegard power supply located in a cabinet near the door up through the roof. The second from that one up to the antenna head. They did not route it through the hole in the base plate.

I think if I can get all the roof putty off from where it comes up to where it connects to the one going up the antenna, I think I can pull the remainder of the old one done from inside. It looks to be a straight shot.
