Equipment / Re: Preamplifier uses
« on: September 05, 2014, 1722 UTC »
I can't see any use for a preamp on the HF bands - the band noise alone would exceed the noise generated by the receiver's front end by quite a margin so no benefit would be realised. all you'll probably end up doing is creating intermodulation products. It may have a use if you are restricted to something like a telescopic antenna a couple of feet long, where received signals are extremely weak.

I'd agree with that - I dare say the loop is performing in the same manner as a length of wire stuck in the back of the receiver would. Inefficient, but still picking something up.
