You must have missed my post on the signal level I got out of my
ALA100. John wants 5.5dbm,or nearly 1.2Vpp if I did the math right. My
ALA 100 produced 120mVpp, so a gain of 10 is needed at the least. I had
30ft of wire in my loop, so the signal strength is probably larger than
an off the shelf Wellbrook loop.

What did you measure from your loop to lead you to the conclusion no
extra gain was needed?
