For amplifiers I recommend a GaAsFet one from
http://www.advancedreceiver.com/page12.html
and get one tuned to your worst case channel. The noise
figure of these is 0.5 dB!! They also make broadband ones but the
noise figure is 2.5dB. That can make a difference. These do need
a separate wire for the DC feed and a weatherproof box. Their overload
capacity is stupendous.

As for antennas ... I was trying to get a channel 44 which is 68 miles
away over a tiny hill. What worked best was a home-made cut to channel
24 element Yagi, scaled from a design found in a 1977 ARRL handbook,
make 100% out of copper tubing soldered together. This was at a height
or only 20 feet. Such antennas are 6 channels wide. I added an extra
reflector behind it cut to channel 19 and that made it work fine
for local channels 17-23 (of course at low gain, the reflector just removes
the back response).
