Thanks Jeff, (and the others that responded)

Summary:

- If you're doing 60 KHz with a loop, you don't need a low noise

front end and you might need a high IP3 amp.



Not 60hZ, nothing here at that frequency, nor 50kHz EU signals.





- If you're doing HF (2-30 MHz), you don't need a low noise front

end, and you certainly are going to need a high IP3 amp.



To be exact, I am looking for MW broadcast using the loop.

and lower HF bands (80m/40m/6mHz SWBC) using a short antenna, similar to

a PA0RDT type (in only that it is a short wire/pole connected to an

amp).


I've never needed a preamp for any of my multi turn MW loops.
I can see how you might need one for a very small single turn loop..
