[Antennas] Vertically Polarized Loops [was: Antennas digest, Vol 1 #17 - 7 msgs]

[Doc]

A loop with vertical polarization is just a horizontal loop fed on
its side, no magic.

Now if your have the loop in the horizontal plane, laying flat, I
am not certain you can cause it to radiate vertically, unless
perhaps you treat part of the feedline (traveling vertically at a
right angle to the loop) as part of the antenna, then you might
get some vertical polarization.

You'd have to ask L.B. Cebik about stuff like that!

Lots of great stuff here and elsewhere on the W4RNL site:

Here is a specific example of a "quad" (square or round matters
little) and how to move the feedpoint to alter the polarization:

You might also treat such an antenna as a "delta loop".  Chapter 4
of "Practical Wire Antennas" by John Heys, G3BDQ, contains an
excellent discussion.

Have fun and share what you discover!
