Although I have several different preamps here from various sources, for a
quickie wideband unit with fairly low noise and high gain (20 db well into
UHF but falling to a measley 11 db at 2 Gigahertz hihi), check with Clifton
at www.dckits.com ... think I paid bout fifteen bucks for those I got there
and they use the MAR-6 MMIC...  if you want more gain just cascade coupla
these (paying attention to the necessary shielding and decoupling); I added
band-switching to two as well as some additional parallel tuned circuits to
put peaks in the response...

My only connection with DCkits is being a very satisfied customer for a
decade and also having Clifton come up with solutions to coupla pesky probs
I had with some receivers...
