Had a similar problem this weekend on my new 284BHS, but with a satellite dish. No signal. After making sure the coaxes were properly attached behind the jack under the television, I plugged in directly from the dish to the receiver, bypassing the TT. Got a signal. Then I checked the TT coax with a multimeter. It checked good.

Then I realized that there was some caulk on the threads of the outside jack. This was keeping the coax connector from screwing in all the way. Cleaned that off, took care to make sure the wire in the center of the coax was going into the jack, and tried again. Went back into the TT, and everything worked.

So, check and make sure the coax is screwing into the outside jack far enough. I have about 25 years of experience dealing with satellite dishes, and felt a bit dumb about how long it took me to figure it out, but it works now.

As it turned out the directions on the wall plate were incorrect. It wanted the jumper attached to A and B. This only allowed air reception with light on. I found an unconnected coax in the area, disconnected jumper from A port, connected the new coax to A and got cable. So now we have a different problem. Set 2 in bedroom picked up no cable on first scan, one channel on second scan, then lost it on a 3rd scan. But turning boost back on and switching to air, the scan picked up many local channels BUT Set 1 would no longer pick up any air, as it had before, So we went back and forth depending which set we wanted to watch, a real pain. Set 1 still won't pick up air tonight where we only have air. Set 2 picked up a number of channels. So I'm stumped. Maybe stupid, too. I looked at the wiring diagram you sent and will pull things apart when we get home. But it would seem sets 1 and 2 should pretty much pick up the same stuff.

I had a DISH guy come out last year on another trailer and get me a picture. I've had DISH from their first year, used to haul the dish from home to cabin, screw it down to a hunk of RR tie and point it. Sure as H can't do that anymore! Bottom line, the guy ended up having me run coax directly from dish to inside the TT and into the Telly. He said half the trailers can't handle a sat signal. Have you had that experience? In the future we'll be setting up a DISH for extended stays and I'd sure like it to work the proper way and not fish coax all over the place, displeasing DW.

And I resolved the WH problem. Thanks to everybody who commented on both subjects.

When he says that, he means there is excessive signal loss. The loss can be from poor connections, or from poor quality coax. A simple multi-meter will not tell you the loss conditions. Without special test equipment, it comes down to trial and error.

For the connections, check to see that any connectors are clean and firmly tight, that is, more than finger tight. Ideally, the coax within the TT has a minimum number of connectors in line. Each connector represents some degree of loss.

For the coax itself, the grade of choice is RG-6. An older, higher loss cable sometimes used, is RG-59. Often, the coax will have the numbers printed on the cable jacket. Another way to tell, the RG-59 is 0.242 inch outside diameter, and RG-6 is slightly larger at 0.266 inch outside diameter.

Hope this helps.

Thanks, David. Connections are finger tight. Will snug up. Also, I'll check my coax as to which it is. I'll look for the numbers. Of course, if they are blurry I'll just eyeball it for the couple hundredths difference. Left my calipers at home.

Well, I just cracked the mixing valve open a bit. Cooled it a bit and now have plenty of hot water. Probably not a permanent fix but good enough to get home on.
