Simple Ham Radio Antennas: A Multiband Loop Antenna, 80 meters through 10 meters. Post #326.

An excellent video guide to building, erecting, and maintaining a simple 80-10 meter loop antenna. Lynn (NG9D) covers the basics in a short, well-produced video that can be applied to many home situations. With careful attention to detail and choice of wire, the antenna is fairly stealthy--something of concern to many of us "penned in" by neighbors and nearby buildings. Lynn uses commonly available RG-58 and RG-59 for the feedline. If you can't find two tall supports, try designing the antenna as a delta loop. A tall tree limb or a telescoping fiberglass mast could serve as the apex of the loop. If space is a concern, you could build the loop for 40-10 meter coverage. If you're worried about high SWR on the coax, feed the loop in a bottom corner with 450-ohm ladder line. Run the ladder line to a balanced antenna tuner or to a 4:1 balun. Fifty-ohm coax would then run from the balun to your antenna transmatch (tuner) and onto your rig. Either way, the design outlined by NG9D is a good, basic antenna that will keep your log book full. Building antennas is half the fun of Amateur Radio. For the latest Amateur Radio news and events, please check out the blog sidebars. These news feeds are updated daily.

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
