If you're having trouble viewing this video, please insert this title link into your browser search box: https://youtu.be/ddbrweVlhCE.  At one time, I was one of many radio amateurs that couldn't work stations on 160 meters because of the large amount of horizontal or vertical space a dipole or quarter wave vertical for this band would occupy. In this video from Stan Gibilisco (W1GV), we learn how an "Inverted L" antenna can help you get on "The Gentlemen's Band."  Stan does a good job of explaining the general theory, construction, and use of an inverted L antenna, which can give you a decent signal, provided you use a good ground or counterpoise system along with the vertical and horizontal dimensions of this antenna.  If you feed this inverted L with open wire, ladder line, or television twin lead, you can get reasonable performance on all amateur HF bands from 160 through 10 meters.  Try to get the vertical element as high as you can and then stre

Simple Ham Radio Antennas--The $4 Special Antenna, Joe Tyburczy (W1GFH). Post # 807.

The $4 Special Antenna by Joe Tyburczy (W1GFH) (http://www.hamuniverse.com/fourdollarspecialw1gfh.html). Accessed on 16 June 2016, 05:01 hrs, UTC. Author:  Joe Tyburczy (W1GFH) and N4UJW. With the ARRL Field Day set for 25-26 June 2016, many of my fellow radio amateurs are looking for a simple antenna that can be built, erected, and used for this portable field exercise.  I ran across this article in http://www.hamuniverse.com and found that my own emergency antenna was similar to the one designed by Joe Tyburczy (W1GFH).  I carry this easily made antenna in my van along with an antenna transmatch (i.e. "tuner"), a fiberglass telescoping mast, some rayon rope, #14 AWG house wire, some basic tools, a homebrewed 4:1 current balun, and 50 feet/15.24 meters of 450 ohm ladder line. I use two deep cycle marine batteries and a solar charger to run my portable station. Joe's instructions are clear and well-presented. If you use locally available materials, you should kee

If you're having trouble viewing this video, please insert this title link into your browser search box: https://youtu.be/CbQwLPVmG70. In this well-made video, Brian Downs (W3ATT) show us how to use two "ham stick" 20 meter mobile antennas to create a vertical dipole for portable or emergency use.  This antenna also could be used as a quickly-erected antenna for those living in HOA-or CC&R-controlled homes or apartments.  Brian does an excellent job of showing just how easy it is to get a vertical dipole antenna assembled and used. With the use of a balanced feeder, such as 450 ohm ladder line, connected to a tuner/balun combination, this antenna could be used on any amateur radio band from 20 to 10 meters.  A nice, simple, inexpensive, and highly portable antenna.  For the latest Amateur Radio news and events, please check out the blog sidebars.  These news feeds are updated daily.  Thanks for joining us today!
