Simple Ham Radio Antennas--Open-Wire Dipole Antenna

If you're having trouble viewing this video, please insert this title link into your browser search box: This is post #975 in a continuing series on simple ham radio antennas. Here's another great idea for an inexpensive, efficient, and easily made antenna suitable for either home or portable use.

In this video, science writer Stan Gibilisco (W1GV) shows us how to design, build, and use an open-wire dipole antenna.  This antenna, designed for the lowest HF band of your choice, and fed with 450 ohm ladder line, 300 ohm television twin lead, or 600 ohm balanced feeders and attached to your transceiver via a balanced ATU or a balun/"tuner" combination will cover several HF amateur radio bands with only one antenna.

This particular antenna uses 450 ohm ladder line to feed two equal horizontal antenna elements, each measuring 20 meters/65.6 feet.  Used with a suitable ATU, this antenna will cover all amateur radio bands between 80 and 10 meters.

You can deploy this antenna in a variety of configurations, including horizontal dipole, inverted vee, and half-wave sloper.  The emergency HF antenna at my new homesite in the Puna District of Hawaii Island is an inverted vee using Stan's measurements and fed with 450 ohm ladder line into a 4:1 balun/manual tuner combination. The antenna works very well from my location in the Central Pacific.  The open-wire dipole also performs admirably on the international shortwave bands. If you need a versatile, multiband HF antenna, then the open-wire dipole may be what you're looking for.  Besides, it's more fun "rolling your own."

G5RV Multi Band HF Dipole Antenna. Post #1555.

If you can't see the video, please insert this title URL into your browser search box: This well-produced and richly illustrated tutorial on the classic G5RV HF Dipole Antenna was presented to the Brandon Amateur Radio Society in Brandon, Florida in 2017 by Bernie Huth (W4BGH).  Bernie does an excellent job of  explaining the pros and cons of this popular HF antenna from the late Louis Varney (G5RV).  Although Varney envisioned his design primarily as a 3/2 wavelength antenna for the 20 meter Amateur Radio band, radio amateurs have used the antenna for multiband use.  The G5RV is an excellent choice for the 20 meter band.  Performance on other HF Amateur Radio bands is good enough to qualify as stand alone HF antenna if you can only erect one HF antenna.

Amateur Radio Bicycle Mobile Setup. Post #1554.

If you can't see the video, please insert this title URL into your browser search box: Here's a way to use Amatuer/Ham Radio while you work on shedding a few pounds in useful exercise.  Why not equip your bicycle for 2 meter/70 cm mobile operation? In this short, well-made video, "taverned" shows us how he used a mag mount antenna, a simple C clamp, and a basic ground system to convert his mountain bike into a mobile station.  The project is straight forward, simple, and gives you emergency communications while you peddle down the road.

An 80-Meter Vertical Helix

Like many amateur radio operators, I live on a small lot surrounded by neighbors, utility lines, and civic-minded citizens concerned about the "attractiveness" of my community.  Whether by design or outright fear, I've adopted the "stealth" approach to ham radio antennas.  It's the old "out of sight, out of mind" idea applied to amateur radio antennas. The amateur radio press is full of articles describing the struggle of amateur radio operators to pursue their hobby under the burdensome regulations of CC & Rs, HOAs, and other civic minded citizens who object to antenna farms.  So far, my modest verticals, loops, and inverted vees have blended well with the vegetation and trees bordering my small backyard.  Vertical antennas have always been a problem because of the limited space for a radial system.  There are times, however, where a shortened vertical for the lower HF bands (such as 80/75 meters) is necessary where horizontal space is lack
