My antenna goal is to have one antenna and to squeeze as much performance
out of it on as many frequencies (500KHz-30MHz) as possible. That, my
friend, can be most closely accomplished with a large loop. However, I am
intriqed by the 15ft vertical that is diagramed at the Kongsfjord noise
measurments link.

An inverted L, 15 feet vertical and 30 feet horizontal, works fine too.
You can make it longer and higher, or amplify it if you want more
signal. Though more sensitive to horizontal polarization then the
vertical, the L still beats the ALA 100 by about 10 dB S/MMN in the
near field of power lines, just like the vertical. I used verticals
for the previous comparisons because those were what I am using
currently (verticals give me better phaser performance in the MW band
than L's).
