[Antennas] Johnson Tuners

[Les Severson]

Hi All,

Concerning the use of coax with the Johnson 275w tuner, by all means
it does tune coax.  Many hams have added a SO-239 connector to the
back panel.. Wiring consists of a simple jumper.  (details upon request)

Another little unrealized fact is that the 275w version will easily 
handle more
than a KW SSB PEP output.  The power rating of 275w was a conservative 
estimate for 100% AM modulation.  My little Johnson box doesn't bat an 
eye at the output of my Kenwood TL-922A amp on any band. (used for a 
balanced fed dipole)

  With all the renewed interest in balanced fed all band dipoles I am
wondering why some manufacturer hasn't resurrected the link coupled, 
Johnson design for a tuner.  It sure beats cranking a rotary inductor 
and a 4:1 balun for feeding a balanced line.
Just look at what Johnson tuners are going for on Ebay.. hi

73 to all,  Les, W�OJH
