Re: [QRP-L] What difference can a different transmatch (antenna tuner) make?

Interesting...my Z-11 Pro into three different PAR EndFedz and a home brew 17 dipole show a good match across the bands for 40/20/17...coax feed...tuner at TXCVRs (Icom 718 and LNR LD5)...using an MFJ 259B to verify...
Maybe I'm lucky...

Obviously, many radios have internal autotuners, too. I am not a fan of
in-shack autotuners, personally.
I have experimented with several SGC autotuners over the years. They
are all different. I have one that will tune a 23' vertical on 160m, but only
handles relatively low power (fine for QRP).
I have another that will handle 500w (not so QRP), but requires a very
long radiator for 160m (like 250').
Both require 12v and a coaxial cable connection. The VSWR on the
coax is close to 1:1 so loss is there is fairly low. For flexibility and the
coverage of many bands, I find them hard to beat (like 160-6m with a
single 23' radiator). Obviously, performance varies and a 250' wire
works quite well on some lower bands. :)
