So my Vizio TV started to have issues where when using the tuner watching OTA channels that after 10-15 minutes the speaker will make a high pitched noise and the screen will go gray with green and red dots and than TV will shut off after five to seven seconds. I can watch HDMI sources without any issues, has anyone see or experienced similar behavior?

Recently I switched from my Gray-Hoverman to the Antennas Direct ClearStream 4 MAX. Seems to work about as well as the old G-H in my attic (one-story ranch home), but the Antennas Direct unit can be mounted outside on my chimney if desired.
I should mention that I was also using a 29-inch "T" shaped antenna for RF channel 11. I know you're not supposed to use TWO antennas unless they have the same length coaxial cable going into your combiner (and even then there might be problems). So I made sure the cables were equal length.
Years ago I made a "T"... -

All,
I recently moved to a very rural area. I am about 25 miles from the nearest urban settings (2 separate College Towns). 45-50 miles from a Urban City (Toledo Ohio)
There was a Omni-directional Wineguard Antenna (amplified) that was mounted on the house originally. Came with the house. Center of the top of Roof a few feet from Chimney on a 4 foot pole. The 75 ohm line went from the roof down 2-3 stories to the small Wineguard amplifier and then it split to the living room and master bedroom. Currently a Very simple setup.
Since we moved in, 8 years ago,... -
Hello all,
Recently I'm upgrading my Gray-Hoverman antenna. Original design. I cannot use a "double-stacked" antenna because of attic space. I do not wish to mount anything to my chimney.
I am using a separate antenna for WHAS Channel 11 (they are using RF Channel 11, 198-205 MHz). I replaced my 29-inch "T" antenna made out of #12 or #10 wire. I made a 58-inch "T" antenna out of 0.25-inch copper tubing. Hooked it up with a matching transformer to the 75-ohm coax going to my TV. I held the "T" antenna up against my ceiling, less...
