Sporadic "No Signal"

Please find my signal analysis. Recently, I have noticed that all the channels lose there signals. The pictures freeze/pixelate and the I get a blank screen with "no signal" message. The weather is perfect outside, no wind, rain etc.

I have not noticed any changes around our location such new construction or towers etc. Nor made any change to the system.

Any reason why this may be happening?

Thanks in advance!

What is the antenna you using? Is a preamp or amplifier connected? Where is the antenna located? Is this a house , apt. , town home , condo , motor home , mobile home , etc.?

Are you using new coax cable or something that is old?

Thank you for the questions.

1- I am using a Wineguard antenna ( I do not know the exact model but it it has a Y type configuration.
2- Antenna is installed on a single story roof.
3- TV is against the same side of the house as the antenna
4- I believe we are using a new coax
5- I think we have something like a preamp. It is accepts the coax from the antenna and is powered ( has a red power light on it), and from there it feeds into the TV.

Hope this helps - I am not too technical!

Try removing the preamp. I suspect it is overloading your tuner with too much signal on the green signals.

Did you install the antenna and Etc. ? Look at the http://www.winegarddirect.com web site and select a model number that is most like the antenna. And what about the amplifier , is there a amplifier unit at the antenna also , what about a name and model number ?

First problem:

You can't use a normal preamp, WHBF on channel 4 is too strong. The other stations are strong enough to work without a preamp. You could use a Winegard AP-4800, it bypasses VHF and amplifies UHF only.

Second problem:

You have stations from multiple directions, but a single antenna and no rotor. To pick up most of the stations properly the antenna should be aimed at 153°. You'd want a second VHF antenna (CS-600 or Y5-2-6) for WHBF and aim it at 84°.

Use a HLSJ to add the two antennas together.
