[Elecraft] New list member/T1 tuner questions

[qrp_1 at juno.com]

The specifics on the antenna are that it is center fed.  The actual
length of each leg is something that I personally do not know because the
ham friend that helped me with it has a special tape of tape measure that
is calibrated to measure antenna lengths.  His is the only one of that
kind that I have ever seen.  The feed line is 300 ohm television twin
lead. [[snip]]

Hello Jim,
  I saw two of those tape measures once and they were actually part of a
military dipole antenna system.  The original antenna had 2 of them and
you just pulled them ou to the coresponding frequency measurements on
each side and you had a resonant dipole for that frequency.  So if your
friend used that to measue the wire with, then its most likely somewhere
around 33 feet on each side.  Being fed with 300 ohm balanced feedline
makes your antenna a doublet - and a doublet is a very good all band
antenna !  I use a doublet here that is 178 feet long - 89 feet per side
and fed with 450 ohm feedline and it works 10 thru 160 meters via the
tuner.
