Over the past couple of days I’ve suddenly started seeing that some channel’s signals are too weak. Nothing has changed in my setup and configuration (that I know of) and today when I did a new channel scan I went from getting 16ish channels (including sub-channels) to 88 channels. In fact I lost the ABC affiliate altogether.
Yesterday I power cycled my Tablo and made sure the coax connections inside the house were tight. I’ve also made sure there are no trees in the line of sight. Should I get up on the roof to make sure the connections are all tight up there? What other trouble shooting steps can I take?
You may need to repoint the antenna. Get your compass and bearings you will need.
Several things could have an effect on reception:
- Repack - stations are behind due to Covid-19 and other factors, and the station could be on a temporary lower power.
- Weather - during summer/winter months, or when storms or wind is blowing, it can have an effect on reception - especially for fringe channels.
- Repair/maintenance of TV towers.
First thing - call and/or email the station to see if something they are doing is having the problem.
If they are not, then make a log as to when the channel is falling out. I lose channel 14 in Austin during the summer (June-September) quite often due to tropospheric propagation (in the old days - we called it “skipping”). Basically what happens is the hot/cold layers of the atmosphere cause a signal to bounce. Channel 14 out of Houston (200+ miles away) will come in clear on many nights here - especially when temps are over 100 during the day and under 80 at night here. On these nights, I pickup channels from both Houston & San Antonio, and lose a couple of channels here in the Austin area - as competing channels will “cancel each other out” (in the old days, they “ghosted” images over each other).
Normally, I get 42 channels, when the weather is just right, I have picked up over 70 channels (Austin, Houston & San Antonio Markets). Of course, they don’t last very long, and the next day by 10:00AM, they are back to normal 42 channels.
Thanks for the suggestions.
Figured it out. Ha! My neighbors connected to the antenna and disconnected my coax because he didn’t know I was using it. We’re getting a signal splitter today to get the signal to all of our units.
