Craig,
While you can feed ladder line directly to anything (including a KX1),
the enclosure and whatever is connected to it can create unbalance on
the ladder line. The result is that the antenna tuning will change
depending on how the KX1 couples to ground - the antenna will behave
differently with the KX1 running on batteries compared to running from a
power supply.
It is wise to use a 1:1 current balun to decouple the ladder line from
those 'ground effects'. Use a 4:1 current balun if it provides a better
match to the antenna. An Elecraft BL2 is ideal, it has a switch so you
can change from 1:1 to 4:1 and use whichever matches better.

Can you feed 300 ohm ladder line right into a KX1? Will it tune it? I guess
I should try it... I always add a balun.

Subject: [Elecraft] BNC To Twin Lug Adapter
Does anyone know a source where I can obtain one of those BNC to twin lug
adapters for the KX1? I am thinking of puuting up a G5RV fed with 300 ohm
ladder line.
Thanks and very 73/72!
