Topband: Dual loaded loop receiving antenna Historical Evolution

[Rick Kunath]

JC,

Thanks for posting this.

That first link doesn't work, it comes up article not found. The W7IUV 
link is down also.

The Dallas Lankford files have been removed (by request) and that Yahoo 
link is not valid any longer, but there are complete sets of his papers 
floating around on the Internet still.

Just wanted to mention that.

Rick Kunath, K9AO

The present invention relates to short wave antennas and, more particularly, to antennas for receiving horizontally polarized waves over a wide band of frequencies. An object of the present invention is to enable the reception of horizontally polarized signals over a wide band of frequencies such-as is at present used in television.
