I have been following the antenna discussion and a lot of people
point to the low noise antenna web site
(http://www.anarc.org/naswa/badx/ante...e_antenna.html).

This site recommends a 9:1 impedance transformer. That matches
impedance, but you also lose 3:1 on your antenna voltage. I can put
a JFET in a box and get the same ratio, but without the voltage loss.
Other than the voltage needed, what would be the down side? The
power is so small, 4-AA batts will run it for a year, even if I
forget to flip the switch.

There are good JFETs that are a least as "flat" in response as the
transformer.

I always check the "prior-art" before I build something. But I will
be trying both this break.

TIA,

Steve.
