Simple Ham Radio Antennas--Do small tuned counterpoises work with HF vertical antennas?


If you're having trouble viewing this video, please insert this title link into your browser searchbox: https://www.youtube.com/watch?v=9yARhBgi020. This is post #880 in a continuing series discussing amateur radio antennas. Great video tutorial from Peter Parker (VK3YE). Long radials are a hassle in a portable or emergency situation. Ground-mounted radial wires can present a safety hazard to both animals and people.  In this video, Peter uses a television rabbit ears antenna along with a variable capacitor to create a tuned counterpoise for his 20 meter vertical antenna.  The small tuned counterpoise system works very well and reduces the chances of someone getting tangled up in a ground radial system. Of course, Peter's location near a beautiful Australian beach helps launch a decent signal.  If you don't have sufficient room for a ground radial system, try this idea from Peter.

Simple Ham Radio Antennas--Coat Hanger 2 Meter Yagi Antenna. Post #879.


If you're having trouble viewing this video, please insert this title link into your browser searchbox: https://www.youtube.com/watch?v=fLOvSLXDudU. Another quick and easy antenna idea from Dave Tadlock (KG0ZZ).  In this video, Dave show us how to build a simple, efficient 2 Meter yagi antenna out of metal coat hangers. You could also use roll up metal rulers sold in hardware stores for the antenna elements.  Your boom could be made from pvc pipe, wood, or bamboo. Just follow Dave's simple instructions and, in no time, you'll have a fully functional yagi that will "hit" those distant repeaters.  This antenna is great for contests and DX hunting.

If you have no room for a tower, but still want the performance edge extra height gives your VHF/UHF signal, you may want to try this intriguing idea from Glenn (N6FN).

Glenn has built a rig that "transmits significant power using a thin wire.  The wire is used to send the power at high frequency down the wire at which point it becomes more like a transmission line than a conductor."  Glenn adds that his signal " is rectified to DC on the other end to power a quadcopter drone" supporting the antenna wire.

Glenn has included some interesting graphics and a video showing the evolution of the drone supported antenna.

Simple Ham Radio Antennas--Mobile HF HAM Radio - Vehicle Bonding and Reducing Ignition RFI


If you're having trouble viewing this video, please insert this title link into your browser search box: https://www.youtube.com/watch?v=6LJkmcgIf-0. This is post #877 in a continuing series on amateur radio antennas.

Excellent tutorial from "remingtonh" on how to reduce ignition noise in a mobile HF ham radio installation.  The key is good bonding and grounding, especially in vehicles where there is more fiberglass and plastic than real metal.  A clear, concise video that should give you some valuable suggestions on how to install a mobile rig in your car, truck, or van.
