Hi;
Buying the antenna and support structure and antenna is the easy part. The harder part comes when the boxes show up at your door.

Hi Richard,
Your right, you'd get about an s unit going from 100 to 500 watts. Remember,
an s unit is supposed to be a 6 dB increase or decrease in signal strength.
Your change from 100 to 500 watts would give you about a 6 dB gain in signal
strength.
If you can do it, more antenna gain will trump lotsa watts every time.
Consider that an increase from 100 watts to 1,600 watts, more than our legal
limit, yields a 12 dB increase in signal strength--2 s units. I can buy a
lot of antenna and support structure for the same price I would pay for a
kilowatt amplifier.

Hello;
Can't resist my two cents on the amp issue. I would much prefer a 60 =
foot tower with a nice six element beam. Unfortunately, it is much =
easier to buy an amp than erecting the tower. If an amp isn't =
overdriven a signal isn't to wide. As for tvi type interference, true =
an amp can aggravate that problem. I found that going from 100 to 500 =
watts gives you about an extra s unit.
