[Elecraft] Auto tuners compared?

Thu Apr 4 16:03:01 2002

Here is a spread sheet I put together for two SGC and 2 LDG tuners

Not related or business oriented and comments are just what I dug
out from on line documentation.

I had an SGC 230.  It was quite good at matching almost any
antenna I tried
including whips, long wires, and loops from 1.8-30 MHz.  It failed
to match a
1/2 wave wire on its exact resonant frequency, but changing the
length of the
wire a few feet fixed this.  It is in a waterproof box and so can
be mounted at
the feedpoint.  It's very well-built and relatively expensive, but
it is
available discounted (and of course second-hand) at more
reasonable prices.  I
haven't compared it to the LDG remote model, but I believe it has
a wider range
of impedances that it will match.  I would buy one again if I
needed this
functionality.
