[Elecraft] Twinlead feedline to my K1

[Ron D'Eau Claire]

There are those that argue a balun is unnecessary, and that an 
antenna/feed line/tuner system will work well without it.  I would try 
just connecting one lead to the red post and one to the black post of
your 
K1 and see if it tunes up!  You may be pleasantly surprised.

Yes, that often works and works VERY well! However, parallel wire
feeders like twinlead or open wire lines will radiate a great deal
unless the currents are balanced. Also, they pick up r-f all along the
length of the feeder when they aren't terminated in a balanced load at
both ends.

Many "windoms" and other off-center fed antennas count on the feeder
radiating and picking up signal for part of their performance.

If you are going to let the feeder be unbalanced and radiate, treat it
just like your end-fed wire. Keep it in the clear, get it up as high as
possible and in the clear as quickly as possible, and be aware that
everything near it will absorb some r-f. Also, any sources of noise
(motors, computers, etc.) near the feeder will add QRN to the signals.
