Absolutely agree with Jim, those bias resisters are
the worst possible value - maximum noise match!

Must be at least 10 times that for the small antenna.

Intermod can be a problem here too - very hard to passive
low-pass filter before the FET without introducing lots
of noise.   Just have to have a very linear wide band
first stage.
