High Performance 40 Meters Vertical Without Radials - W6NBC
At my club’s remote base station only 5 turns were ultimately needed, and only 4 in my big oak tree. Make up a jumper (Figure 4) to short out unneeded turns ... Yet from square one in ham radio, now nearly fifty years ago, I had always heard it proclaimed, “More height is ALWAYS ... careful attention to in this design, is antenna efficiency ...

www.arrl.orgexample. In the typical ham station setup, a transmitter is connected to a feed line, which is then connected to the antenna. When you key the transmitter, it develops a radio fre-quency (RF) voltage on the transmission line input. The voltage travels down the feed line to the antenna at the other end and is called the forward wave.

The Slim JIM Design From the book, the slim JIM was developed based on the basic J-Pole design, see Fig.1. Both are omni-directional. The J-Pole antenna became so popular in the VHF band because of its simplicity in design and construction.
