[Elecraft] Re: KAT100 with Ladder Line

[Joe-aa4nn]

Hi Peter,
Try not to worry too much about feeding balanced lines.
Get the Elecraft BL2 and hook it to the balanced line.
Connect a 2 or3 foot piece of coax from the BL2 to your rig.
Tune up and away you go.  If the balun tends to get a little
warm, just cut off 5 or 6 feet of the balanced feedline and
give it another go.

You don't want to connect balanced line directly to KAT2.

73 & gl,
de Joe, aa4nn
