The 6 meter (50 MHz) Amateur Radio band is a fascinating group of frequencies often called "The Magic Band" for its fascinating propagation characteristics. The band exhibits both HF and VHF properties and can sometimes reach out thousands of miles. In this video from Peter Parker (VK3YE), we see how an old VHF television antenna can be recycled into an efficient 6 meter ground plane antenna.  The radiating vertical element and the radial wires are both 1/4 wavelength long and vary depending on the chosen frequency. Peter says he has received many contacts using only 5 watts of power.

Randy Hall (K7AGE) has produced another fascinating and easy-to-follow tutorial for radio amateurs.  This time, Randy takes us step-by-step in making a 20 watt QRP Dummy Load.  The material list is simple and readily available from several Amateur Radio stores and distributors.  You may have some of these components in your "junk box." Material list: 8 X 100 ohm 3 watt metal film resistors. 1 X 1N5711 diode. 1 X .001 uF capacitor. BNC or SO239 connector. The dummy load even has a test meter to measure the voltage used in your QRP transceiver.  A very nice weekend project.

The ARRL 2017 Field Day is approaching, with the emergency communications event set for Saturday and Sunday, 24-25 June 2017.  If you want to make an effective multiband HF antenna for those days, check out this video from the Montrose Amateur Radio Club which designed, built, and used an antenna on site for the 2013 ARRL Field Day. Notice the use of 450 ohm ladder line and the antenna "tuner" to get multiband coverage.

Here's part two of "DENMONKEY's" 40 meter delta loop antenna.  In part 1, we gathered the materials, worked out a practical design, and began attaching the stranded electrical fence wire to the delta loop design.  In part 2, we get ready to finish the construction and begin testing of the antenna.  Delta loops are simple, low noise antennas that can readily be applied to NVIS (near incident skywave) operations, Field Days, or other portable communications requirements.

Full-wavelength HF loop antennas are especially useful in high noise, urban areas.  A Delta Loof HF Antenna, whether it is a monoband project using 50 ohm coaxial cable as the feedline or a multiband affair using balanced feedline to feed the antenna, is a worthwhile project that will reward you with plenty of contacts. The antenna is fairly quiet and is a perfect antenna for NVIS (near vertical incident skywave ) applications. In this video, "DENMONKEY" provides a useful, easily understood tutorial on how to make a simple 40 meter Delta Loop HF Antenna from common materials found at the nearest home improvement or hardware store . In part 2, we'll see how our preparation pays off, as the antenna is raised to its operational height. For the latest Amateur Radio news and information, please visit these websites: http
