Simple Ham Radio Antennas: A Random Wire Solution for an "interior shack". Post #318.

Here's another great antenna idea for those amateur radio operators limited by HOAs and CC & Rs.  Stan's "stealth antenna" is simple, cheap, and easily deployed for both home and portable use. When I first became a novice licensee back in 1977, I used a similar antenna at a rented home near the Honokaa High School campus. The community was located along the Hamakua Coast of Hawaii Island and had an excellent clear water shot to the mainland United States and Europe. The only difficulty I had in those days was the lack of a decent back yard to support a dipole or a radial system for a vertical antenna. I did have a tall Norfolk Pine Tree in the back yard which I "recruited" to support the end of my random length wire. I used an 85-ft/25.91 meters length of #22 AWG wire for the radiating element and a 17-ft/5.18 meters length of #22 AWG wire for the counterpoise. My crude antenna was a variation of the once popular "Zepp" antenna used on the German dirigibles of the 1930s. I used a 50-ft/15.24 meters length of 450 ohm ladder line for the feeder. One leg was attached to the longer antenna element, while the other leg of the ladder line was attached to the shorter counterpoise. I shot the antenna element over a branch about 30-ft/9.14 meters above ground with a slingshot. A ceramic insulator was tied off at the end of the antenna element and was used as the weight to guide the antenna line over the tree limb. A short length of nylon cord attached to the insulator was used to secure the antenna element to a nearby fence post. The counterpoise was attached to the side of the house. The ladder line was run into a W9INN 4:1 balun, which was attached to my Drake MN-4 antenna transmatch by a 10-ft/3.04 meters length of RG-58 coaxial cable. The coax from the transmatch was attached to my first rig, the old Heathkit HW-101. I had a ball with this antenna, which worked very well on 40 and 15 meters. When I passed my General Class license, the antenna was pressed into service on 20 and 10 meters with good results. I must admit that Stan's random wire antenna is more effective and perhaps more efficient than my original antenna. So, if you want a simple and somewhat stealthy antenna, try Stan's random wire design. It will produce many hours of enjoyment at a modest cost.

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
