Discovery: Coax Cable routing and Identification

[Lawgiver]

Hello Everyone,
Recently purchased a 09 40X. My first DP upgrading from a gas coach. The learning curve has been steep to say the least. I would like to know if anyone knows the routing/location of the antenna coax cable. I have no signal or power to/from the roof mounted antenna despite 12v power at the video switch box. I was able to obtain a diagram from Fleetwood noting "two" unions in the cable. However, they could not advise me of the exact routing of the actual cable. I'm guessing one union is underneath the roof mounted antenna but the second union is a mystery. I would like to locate this second union and verify integrity before pulling the antenna off the roof.


Part two of my question: Does anyone have a guide or legend of the coax cable identification? It's basically a rats nest where the coax cables are located. Some cables are labeled correctly however some just have a label with four numbers, ie 1010, 1011, 1002. Anyone know what these numbers signify? I've attached a photo for reference.


Thanks for the help.

On my 2012 Discovery 40X, I have a cabinet above the drivers seat and there is a removable panel that allows access to the underside of the roof mounted antenna.

From the antenna connection there, the coax cable runs down behind the plastic pillar molding on the left side of the windshield and connects to the back side of the in dash radio. There may be a small amp in line fuse somewhere in the equation, but I've never had a reason to look for one.

Anyhow, go to the following webpage and click on the 2009 40X folder and you'll have all the drawings for your coach:

Hope this helps.

Ps...My roof antenna was just held down with 4 self-tapping screws and black Seka-Flex 221 sealing adhesive. It is easy to remove and lift out slightly to check the integrity of the connection there.

There is a couple of ways to check.
1.All the cables are color coded with color ring at each end.
2. You could buy a toner and tone out the cables. (this is what I did)
Good luck.
