Re: [IRCA] Antenna Projects (Crate Loop)
Dave,
I used a Sanserino Loop many years ago. If I remember right, the amplifier
had 2 FETs and a center tap. The amplifier delivered really good gain, but
the "Q" was wide. This was problematic for receiving TPs on adjacent
frequencies.
Amplifiers typically raise the noise floor with the desired signal and drop
the "Q" a bit. That being said, my 4-foot Box Loop beat the socks off the
Sanserino Loop even though signals were weaker.

>>Thanks Chris:
I will archive your email. The only true "communication receivers" that
I have are a 20 year old RS DX-400 and a Grundig S-350. Both have built
in ferrite bar antennas, so that complicates things somewhat in terms of
directionality. Also both are perfectly setup for using the sense coil
setup. The RS has screw terminals and the Grundig has spring loaded
ones. I had an old Sanserino loop and right out of the little amplifier
was more of the same type of wire that was used in the loop - one side
to A1 and the other to A2 or whatever the DX-400 says on the back. So,
I had no connecting cable, of another material at all. It worked good
and as I had said before I added something like 7 new ones during the
day, the first day and that was at high noon with no skywave. So I'm
confident that the Crate could be similar but would a small amp kick
things up a bit?
73,
Dave in Indy<<
