Back from good old tube days, cascoded triode RF preamps were good for
high
gain, stability and low noise.

Anything out there in transistorised version, or there is there better
stuff
available? Looking mainly for preamps on HF to be used with low gain
antennas,
like small loops or beverages.

Back in the 'good old tube days' it was difficult to get below a NF of 3 db
on 2 meters. Now it is easy to get way below that with a good FET. For HF
almost any RF device now will take you very low in NF with good gain.

There are versions of the cascode that use FETs for HF and above.
