Re: [TowerTalk] Tuners and Matchers

Lee,
Choice of a tuner depends mostly on what you're trying to tune .. 
ESPECIALLY on 160m.
Remember that an antenna tuner serves only ONE purpose .. to 'match' the 
impedance at the shack-end of the feedline to the output impedance of 
your rig/amplifier.
Another consideration is whether or not the feedline is balanced 
[open-wire/ladderline, etc] or unbalanced [coax/similar].
In my [humble?] opinion, a separate tuner for each band of NEED would be 
best .. set it an forget it .. but I would NEVER use a tuner with a beam 
.. if the feedline impedance and the antenna feedpoint impedance are 
correctly matched, there is NO NEED for a tuner.

I currently have a Palstar and it is OK...but 160 meters suffers.  I also have a homebrew tuner that works, but....I want something different.  So to that end, what do people think of the following....(yes, I have read all the reviews I could find in QST and in Eham)

When I was a kid so many years ago, the best tuner for the old long wire was the L-Match...a cap and a coil and a bunch of aligator clips all mounted on plywood.  So, is the L-Match making a comeback in everyones thinking because depending on how you set it up, it can match from 5 ohms to 3000 ohms where the other are not that robust.
