Hayward design broadband low noise preamp for loops

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).
