Simple Ham Radio Antennas

If you have trouble viewing this video, please enter this URL into your browser: http://youtu.be/642N0oWgY5I. A nice, simple tutorial from W0ZF on how to make an inexpensive portable vertical antenna for the 20 meter Amateur Radio Band. I've made a few of these antennas using a fiberglass telescoping mast, some #18 AWG speaker wire, a few insulators, a simple ground radial systems, an appropriate length of RG-8X coaxial cable as feed line, and an antenna transmatch (i.e. "tuner") to keep the SWR to a low level. If you wish multiband use of this 20 meter vertical antenna, you can feed the antenna with balanced line (450-ohm window line or 300 ohm tv twinlead). The balanced line would go into a 4:1 balun and then onto your antenna transmatch using a short length of RG-8X coaxial cable. This simple antenna works.

A comprehensive, well-organized video tutorial on the popular reflector antenna used in satellite dishes. The video from "Pete's Free Information Center" describes the basic physics and theory involved in this type of commercial and amateur radio antenna. The video discusses aperture efficiency, gain estimates, and a little bit about satellite dish design, along with geometric optics approximations used in the analysis of these reflector antennas. A useful reference for those into EME or amateur satellite operations. For the latest Amateur Radio news and events, please check out the blog sidebars. These news feeds are updated daily.

With the approach of summer and the longer days and warmer temperatures that the season brings, many amateur radio operators will be taking portable stations to the field, local parks, and even along hiking trails to enjoy their hobby in the great outdoors. Often times, many of us go off into the "wilderness" with equipment that is a bit too heavy, needs too much power, and requires sophisticated antennas. If you have to carry a lot of weight in addition to your day pack, your pleasant hike may turn into a chore. Dennis Blanchard (K1YPP) recommends going the low-power route (QRP), with a light rig (Elecraft KX-1, Yaesu-817, or even a homebrew cw rig built into an Altoids mint can), and a few light weight dipoles you can string from a tree or other tall structure. Power can be provided by a set of alkaline batteries or a gel-cell battery. In this well-made video tutorial, Dennis reviews what has been historically popular and shows us what he has found to be a workable, e

This time, Stan discusses the theory, construction, and use of a 40 meter vertical antenna for DX. Vertical antennas perform well if they are used in conjunction with a good ground radial system. The radial system supplies the missing half of the vertical element. With a decent radial system, this vertical directs most of its radiation toward the horizon. If you cut the vertical and radial wire lengths for a frequency in the lower portion of the 40 meter band (below 7.100 MHz), the antenna will work very well in the SSB portion of 15 meters as a 3/4 length antenna. This assumes you are feeding the antenna with 50 ohm coaxial cable. If you want multiband use between 40 and 10 meters, feed the antenna with ladder line or tv twinlead. The balanced feeders would then go into a balanced tuner and then on to your

Excellent tower and antenna installation video from David Mercado (KK4MMD) and his father. It appears David did a good job of preparing the construction site and took the recommending building practices into account before he raised the 40-foot/12.19 meter tower and attached the Mosley TA-53 antenna. Perhaps "it's a stretch" to call this installation "simple" because of the tasks involved. If you decide to erect a tower and antenna, be sure to get some help from people who have installed towers.
