Anything special needed to make this thing besides the wire and SO-239?
I might want to transmit through this some day using a random wire tuner
but for now it will be used for SWL.
Go ahead and hook it directly to a random wire tuner, and simply tune
for maximum loudness on a given frequency. MFJ makes an inexpensive
tuner for random wires.

Thanks, would rather get a 10:1 balun for now. Haven't had the time to
google it but there should be some instructions on how to make one myself.
If you use a cable TV Balun you'll get a quick and dirty 4:1
transformer and a marked improvement.

Those don't work well below 10 MHz. 15 MHz and higher they are OK.
