[Elecraft] Balun

[Stuart Rohre]

I guess one of the issues, are you ordering a K2 with its auto tuner?

In that case, my suggestions apply, to adding the Elecraft balun, and using
the internal K2 tuner for your antenna.  It is also true that a balanced
line tuner will work after the K2, and before your ladder line.

Since surplus Johnson Match Boxes do not match on all bands and are harder
to find in surplus; you might check out the new line of MFJ balanced tuners.
They have a double Tee network, and use large, well suited components.  They
go between the K2 and the ladder line, for manual tuning like a Match box
did.

I was impressed with them at Ham Com where they were on display.
In addition to a double network to balance the tuner, they float the tuner
input with a RF choke isolation, to insure you do not couple RF back to the
rig on outside of coax.
