Hello Kevin,

I've heard good things about LNA4ALL (https://lna4all.blogspot.com/), 
which has a high IIP3 and low NF.

The +33dBm IIP3 would help with overload issues on the LNA itself, but 
the high gain (+23dB) would then overload your SDR/rig with those, now 
amplified, high-power out-of-band signals.

If you added an appropriate filter, such as the one I used, to the 
output, then you'd have a good solution.
