Actually, Jake, it is because of the orientation of the pulsing magnetic field on the wires. They run horizontally, and the antenna is vertical. its reception field is at 90 degrees to that which the lines create. It was inspired by an old drawing I saw in one of my books which advised orienting a long wire antenna at 90 degrees to any trolley lines which ran in front of your house. I considered the best way to accomplish thins in the least space, and decided on a vertically oriented antenna. It has the added advantage over a long wire in that it is omni-directional, and receives equally well from all directions. It is really an ideal antenna for my use; it works well for all directions, and takes very little space, just clearance above it, and it minimizes the interference from the power lines. Much more practical for my use than a long wire. Everybody's Radio Manual, page 141...

This is a very useful old book, and has a whole section on how to eliminate interference from your receiver.
