I am interested in building a high gain / low noise amp to use in
masthead aplications for TV reception.

The freqs response required is 180 to 200 Mhz

I have built narrow band units using BF981 and other dual gate Mosfets
and gasfets but cant seem to get the response to be broadband enough
for this application.

Yes I could buy one ...... but wheres the fun in that !!
Some of the kits available (ie MAR series, OM350, uPC 1688G etc ) 
are too broadband and have NF of over 4 Db 

Suggestions / circuits appreciated
