Simple Ham Radio Antennas

Thanks to Denis (VE3BF) for this excellent, easy-to-understand tutorial on how to build a "Long Wire Antenna." The keys to this antenna are a 9:1 UnUn and a good ground/counterpoise system.

This short video by M0VST covers most of the basics involved in making an effective longwire antenna, covering the amateur radio bands between 160 to 10 meters . I've built several of these "longwire" antennas and have found that an ATU ( antenna tuner ) and a good counterpoise system really help to produce a quality signal. Unlike M0VST's "longwire antenna", my version was cut to a length of 67-ft/20.42 meters, enough to cover amateur radio bands between 80 and 10 meters. My counterpoise system was a compromise arrangement consisting of four, quarter wave radial wires for each band of use (80, 40, 20, 15, and 10 meters). I also attached a "quarter wave radial bundle" to the ground lug of my trusty Drake MN-4 ATU. I used approximately 60 ft/18.29 meters of 450 ohm ladder line as the antenna feed line. The ladder line was attached to a W9INN 4:1 balun. A 6-ft/1.82 meters length of RG-8X with UHF connectors ran from the balun to the wi

KH6JRM's Amateur Radio Blog Post #175 A "long wire" antenna One of the joys of being an amateur radio operator is the creation of antennas.  Since I live on a restricted lot surrounded by neighbors and high power distribution lines from the local utility, I have to be creative if I want to get on the air.  Like many of you, I've had to live with compromise antennas most of my amateur "career".  Sometimes, opportunities come along that just beg for experimentation.  Such was the case today, when several of my neighbors mentioned they would be visiting relatives for several days.  Since my teaching assignments won't begin until 01 August (or later, if you are a substitute teacher such as I), I offered to keep on eye on their homes until they returned. Goody!  There are several 30 to 50-foot trees in back of my house on my neighbor's property that just call out for antenna use.  Oh, well, that must be my imagination.  Anyway, I decided to str
