Just the facts please...

Ok, I'm kidding. I'll take any opinion as well. I live in the middle of everywhere or nowhere. Typically about 70 miles from the closest broadcast antenna. On a small hill with antenna at 55' above ground level. Approx 125' coax. Basically I live about 1/2 way between Norfolk and Columbus, Nebraska and my broadcasters are in Omaha, Lincoln, and Grand Island.

I have a Winegard HD-8200U and not sure of which antenna mounted pre-amp. I used to get channels 3, 6, 7, 8, 10, 12, 15, 42 and all the digital subchannels associated with them. It appears my pre-amp has been cooked by a nearby lightning strike.

What should I replace it with? Thanks for any suggestions. Also, would it do any good to put a second amplifier in line before the splitter in the house?
It would be very unusual to find a situation where the use of two amplifiers would be of any benefit. In most situations such ideas only add to the complexity, and increase the potential for problems.
