Acactly what frequencies are you trying to amplify and perhaps more
importantly,
why are you amplifing them?


I see that the ampli on the degen antenna does good ..
I live in a place where the noise floor is LOW .. So ampli makes sense.

I saw that when on holliday in urban regions my am loop didn't add
anything to reception with a sony 7601 ...

I want to ampli freqs like the AM 500-1700Khz, but also SW 6MHZ-17Mhz ..


For LF/MW/HF, unless you are using a loop or a short active antenna,
which
will already have an amp, further amplification will almost alway lead
to
overlaod and other unpleasentness.
At least we need to know:
what type receiver(s) you have.

I intend to use the amplified ant with a drm receiver ..

what type antenna are you planning on using.


loops on AM & SW

what frequencles are of interest.

AM & SW
