Problem with Jack antenna

Sounds like you have a cabling problem, Wrong cable sent to wrong place.. This is something I can diagnose eyes on but kind of hard to do over the net.

My best guess: Whoever did the "Jack" downgrade messed up.

2012 motorhome and Jack is original equipment. The only change was the satellite and we went from multi-swithc to sam which was all on the sat side. If the cables are bad it came that way from the factory.

Did you turn the little black knob on the Jack to decrease the sensitivity of the blue led signal strength indicator? It sounds like it adjusted to its max sensitivity.

Turned it in both directions and all four lights are lit and intensity didn't change.

To find direction and distance to stations anywhere in the country:

Did you put the TV to setup and scan for channels? Each time you move and set up you need to scan for channels. When I had mine on the other MH I did that every time and would get all the local channels.

Has it ever worked correctly or is this a situation that is occurring just at your present location?

It has worked in the past and in the past I was able to have the attenuator go down to one light. Now it shows four lights of the same intensity no matter how I turn the peg or turn the antenna. I located the stations and aimed at them. I picked up ION but not CBS that was very close. Maybe this means something- I had a SWM installed for my winnegard traveler satellite. They bypassed the port in the cabinet and installed their own multi-switch directly to the dish and the receiver. I have a plate with two coax outlets and one is labeled satellite and other portable satellite. I assume the satellite is no longer needed as the SWM is now hooked directly and if I use the vucube I would hook from the coax port labeled portable. I have a plate with coax female in the other front compartment with the push button for the power boost. When I engage it and the green light comes on I can then turn on the Jack. If the green light is not on the Jack does not turn on with its own switch. I have scanned both full and partial, reset to factory settings on Vizio, checked parental controls. Obviously switched from cable to antenna and changed input from comp to TV. I am in Orlando at Disney and have many stations within 30 miles and most are north to north-east. I don't use the Jack very often as the satellite is my preference but I do know in the past I had to turn the attenuator and antenna to get 4 blue lights tuned in and now all I get are four. I also recall in the past I depressed the button in the compartment to get green light and engage the onboard power boost. I am baffled and thinking equipment failure.

If I remember right, when the Jack is installed, you DO NOT use the power supply/amplifier that came with the Jack if your coach already has an amplifier system for the original crank up antenna. I mention this because you mentioned turning the Jack on with it's own switch. On my coach I have a switching box that has it's own antenna amplifier and there is NOT a separate switch for the Jack. Perhaps if two amplifiers are on this is causing the problem.

If you get a whole new Jack ant. then you do not use the old amp. You must use the new one or it wont work.
This is spelled out in the instructions several times.
