Thanks for the photo of your FSM. I am always interested in old meters. If your meter still works, it is entirely adequate for your needs.

0 dbmv was the holy grail of signal levels.
It pretty much still is for a drop outlet to a TV, but tuners can handle a wide range of signal strength.

I used to understand Radio/TV when analogue ruled. Digital seems to have changed the laws of physics :-)
The laws of physics and antennas haven't changed; what has changed is the "Digital Cliff" for digital signals which creates the sudden signal dropout, which is a lot different than increasing snow with weaker analog signals.

In addition, WNYW in NYC appears to have built a satellite station on Mt. Beacon on channel 32. Even though I have Line-of-sight to the transmitter, the signal is marginal, and not always reliable.
I suspect that the transmitter antenna is highly directional and is being 'beamed' in a direction outside of my area.
That is correct; only 0.001 kW (1 watt) out of 1.000 kW (1,000 watts) is sent your way because of the transmitter antenna array.
