During the lull in the current solar cycle, the 10 meter amateur radio band makes an excellent vehicle for local and regional contacts.  Please encourage your friends with technician class licenses to work some CW or SSB on this band.  Why not organize an informal, local net on 10 meters?  You can use Don's project to make something workable for your 10 meter work.  For the latest Amateur/Ham Radio news and information, please visit these websites: http:

20 Meter Delta Loop Antenna. Post 1737.

. If you can't see the video, please insert this title URL into your browser search box: https://www.youtube.com/watch?v=Rq-9TAcCnxE Here's an easy, inexpensive, and versatile antenna from Denis (VE3BF).  The classic delta loop antenna can be used for both home and field use.  The antenna exhibits modest gain and can be vertically polarized by feeding the antenna at the bottom.  To get multiband performance (20 meters through 10 meters), use 450 ohm ladder line, 300 ohm TV twin lead, or homemade 600 ohm twin lead in conjunction with a 4:1 balun and an antenna transmatch (i.e. "tuner").  I've built several variations of this design for 80-10 meter coverage.  Best of all, most of the materials can be found in  your "junk box" or at the nearest building supply or home improvement outlet. Have fun! For the latest Amateur/Ham Radio news and information, please check these websites: http://www.HawaiiARRL.info. http://www.arrl.org. http://www.arrl.or

In this video, Denis (VE3BF) shows us how some wire, a simple 4:1 balun, and an inexpensive fishing rod can become the basis of a great outdoor antenna.  Denis uses a spirally-wound wire on a readily available Shakespeare telescoping 20 carbon fiber fishing pole from Amazon to form a simple, inexpensive portable antenna for 40 meters and other bands.  When you're done with operating, the fishing pole collapses into an easily carried package which can be stored with the antenna components in your vehicle for the next field or emergency situation.
