If you're looking for a simple, efficient, and low noise 6 meter antenna for your ARRL Field Day experience, then this beautifully designed project from Martin (M0ZMF) is what you need. The video consists of five easily understood sections: Materials Construction of the Base Plate Stub production Final assembly Final set up Martin goes into considerable detail on how to design, build, test, and adjust this high-performance antenna.  Not only does this delta loop have exceptional structural design, but it also is fully portable and easy to set up and take down. Give this antenna "a shake down cruise" during the ARRL Field Day in June...you won't be disappointed.

If you need a simple, inexpensive, and efficient HF antenna for the upcoming ARRL Field Day, why not build this "classic" half-wavelength horizontal dipole? In this video, Kevin (N6VLF) reviews almost everything we know about designing, building, tuning, and using this basic antenna.  You can configure the dipole in any number of ways, including the inverted vee, the half-wave sloper, and even a vertical (if you have a very tall support).  You can easily convert the dipole into a multiband HF antenna with the addition of a balanced feed line, a sturdy wide-range antenna "tuner", and an appropriate current balun.  If you follow Kevin's suggestions, you'll have a fully functional, efficient antenna for Field Day in a matter of a few hours. This video would make an excellent presentation for your club or for the ne

If you need an easy to build, inexpensive gain antenna for the 20 meter band, then this basic Delta Loop Antenna may be what you need.  Denis (VE3BF) has done an excellent job of presenting this antenna, which can be used at your home station as well as for the annual ARRL Field Day exercise.  If you use balanced feed line, a 4:1 current balun, and a sturdy antenna transmatch (i.e. "tuner"), this basic design can be used on any amateur radio band between 20 and 10 meters. I've built several delta loop antennas in the past and find them quiet and fairly stealthy in crowded urban neighborhoods. If you follow Denis's suggestions, you'll have an effective 20 meter antenna with little effort and financial expense.

Summary: Approximately 40,000 U.S. and Canadian ham radio operators will join their colleagues worldwide during the 22nd and 23rd of June to participate in the annual ARRL Field Day event.  Field Day is part contest, part emergency communications exercise, and part fun.  Amateur Radio operators will take to the "field" and try to make as many contacts as they can during the short operating window of the event.  Among the stars of this radio happening will be the antennas which will send signals around the globe and through space to reach destinations far and wide. The antennas used will run the gamut from random wires to sophisticated multi-element beams on portable towers.  What antenna will you or your club use during this year's Field Day?  In ord

If you live in an urban neighborhood plagued by noise and other interference, you may want to build what is called a "double bazooka" antenna. The double bazooka antenna is an efficient, single band antenna which is very quiet and does not require a balun.  The antenna consists of coaxial cable, such as RG-58, or other 50 ohm type with the shield split at the center and the feed line attached to the open ends.  The antenna is broad banded, allowing full coverage of a single band without excessive SWR. In this video, Bill (WX4AR) takes us step-by-step through the design, construction, and testing phases of this of easy-to-build antenna. Why not build one for the upcoming ARRL Field Day?  You may be surprised how well this simple antenna performs in a noisy environment. For the latest Amateur/Ham Radio news and information, please
