If you ever wondered what it would take to operate the "Top Band" or "Gentlemen's Band" (160 Meters) from a small lot, then turn to this extensive 109-page treatise from Jim Brown (K9YC).  The study is presented in the pdf format and must be downloaded to your PC, Mac, Laptop, or Tablet.

This well-written and thoroughly fascinating study will answer most questions about operating on the frequencies just above the medium wave AM Broadcast Band.  As you can imagine, designing, building, and using antennas for this band can be challenging.

Don't let restricted space stop you from enjoying one of the legacy bands in Amateur Radio.  In my current situation, I'm using a 160 Meter vertical helix wrapped around a 33-foot/10.06 meters telescoping fiberglass mast. This overgrown "rubber duckie" antenna for 160 Meters uses a half-wave length of #18 AWG speaker wire (264-feet/80.48 meters) wrapped as a spiral (helix) around the mast.  My ground system consists of 4 quarter wave radials, each measuring 132 feet/40.24 meters).  Most of the wire I used was salvaged from yard sales, scrap left over from other projects, and from clearance bargains at Home Depot.  I plan to add more radials as soon as more wire becomes available. The antenna works well for what it is.  Jim Brown (K9YC) covers a variety of 160 Meter antennas, most of which can be built with a little patience.

The large pdf document contains both theoretical and practical discussions of antennas suitable for limited real estate.  This report can serve as a handy reference source should you decide to build a 160 Meter antenna on your property.  Just download the full report and put it into a three-ring binder for ready reference.
