Thanks for the backup. I shouldn't make any posts right after an argument with my wife.

Good; we will try to help you as best we can.

Understood.

Does your TV have a signal strength indicator to help you find the best location for your antenna?

I like the Diagnostics Screen on my Sony KDL22L5000 TV that shows relative signal strength, and signal quality as defined by SNR (Signal to Noise Ratio) and uncorrected errors.

bad signal; picture freeze, low SNR of 13 (should be > 15 dB), and high errors:



good signal:



My newer Sony 32R400A has a wider range signal strength scale with one dB steps; excellent for antenna experiments. It is also able to add a new channel after scan, so it isn't necessary to rescan after changing directions or antennas. I made a calibration chart of the signal strength scale with my Sadelco signal level meter that shows dBm values as listed on the TVFOOL report. See attachment 3.
