[Premium-Rx] Palomar Antennas

[Peter Gottlieb]

Even with my relatively sensitive receiver (RF-590A with bypassed 
preselector) I worry about weak signals from my loop below the noise floor 
of the receiver.  Is there a good low noise preamp I could use which would 
help?  Or would other frequencies swamp it?  Possibly I could insert the 
preamp after the receiver's preselector?  Or am I simply at the limits right 
now?  I guess what I am asking is, what is the best setup to get the really 
weak stations when the antenna is less than perfect?

PS, the PRC-104 receiver seems more intelligible and possibly slightly more 
sensitive, but a pain to tune around the band with.
