FT-857D and MFJ-945E - tuning a light bulb antenna

Radio amateurs have used just about everything as antennas, including rain gutters, balconies, fences, and even light bulbs as shown in this video.  An ARRL antenna book published several years ago had described such an antenna as a fun experiment to see just how effective this extremely compromised antenna was. As described in this video, as long as an object (i.e. a light bulb) could radiate and not shut down the transceiver with a large SWR, contacts were possible.  A few contacts were made with this "antenna" using a Yaesu Ft-857D, a LDG FT-meter, a MFJ-945E mobile antenna tuner, and a MFJ-911H 4:1 current balun. The light bulb antenna was configured as an end-fed antenna.  The light bulb arrangement probably wouldn't be your first choice as a standby antenna, but, it does work after a fashion. An interesting and somewhat amusing video showing what's possible when it comes to antennas.

G5RV Multi Band HF Dipole Antenna. Post #1555.

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.

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 lacki…
