I live in Riverside, CA (about 50 miles east of Los Angeles).

I do NOT have a cable system nor a satellite ("dish") system.

Except for small "dish"-type antennas, the condo-rules allow
"yagi"-type antennas only in the attic of each house. But, knowing how
much signal is lost by attic-installation, my Terk TV38 antenna is
laying on a flat roof (so it's not too conspicuous to the condo-board).
A coax cable runs across the roof for 15 feet, goes down 4 feet into
the attic and is connected to a Radio Shack signal amplifier. A coax
cable then goes from the amplifier, through the attic for about 30 feet
to the TV set.

Here are the channels I get:

Note: KVCR 24's tower has a compass orientation of 51 degrees and is 9
miles from my house. The towers for all of the other channels have a
compass orientation of 287 degrees and are 43 miles from my house.
