I am not sure that this has been discussed before on the reflector,
but will the KAT100 tune a longwire?
Yes. You can connect it directly to the ATU using a binding-post
adapter, or just wire up a PL-259's center pin to an alligator clip or
to the wire itself. Counterpoise goes to the ground lug -- use a very
high-quality ground to maximize transmit efficiency. (House electrical
ground is marginal from both all angles -- noise, efficiency, and
safety.)
A better alternative than direct feed is to use balanced feedline (and
a low-loss 4:1 balun such as our BL1 at the tuner) to get the radiating
part of the antenna *out* of the shack and away from computers, kids,
pets, TVs, portable phones, etc. If you use a random wire without
feedline, you'll likely have to stick with QRP power levels to avoid
RFI.
