Another great and often humorous approach to supporting stealth wire antennas from Callum McCormick (M0MCX).  In this video, Callum shows how aluminum scaffold tubes slip inside sail board/wind surfing masts to make cheap, economic, and structurally sound supports for hidden or stealth antennas.  You could also use telescoping fiberglass masts, PVC pipe, and even bamboo to fashion antenna masts for hidden antennas.  Callum offers many suggestions on how you can raise and support stealth antennas, especially for radio amateurs who have no trees on their property.

How a simple counterpoise system can lower your SWR. Post #1534.

Every vertical antenna needs a ground radial or a counterpoise system to realize maximum efficiency and reduced SWR.  If you can't lay in a ground radial system, then a counterpoise system consisting of 1/4 wave length wires running parallel to the ground, suspended over the ground under the vertical antenna will insure that SWR is tamed and that your vertical antenna is radiating more efficiently.  In this video, the antenna in question is a tri-band 6 meter, 2 meter, and 70 cm vertical with added counterpoise wires.  An interesting project that you can complete in just a few hours.

Please click link to read the full article and related topics. Comment: I've always favored "homebrewed" wire antennas for the annual ARRL Field Day, which occurs on the third full weekend of June.  Whether I've opted to run my portable station in my backyard (because of work requirements) or chosen to help with the Big Island Amateur Radio Club Field Day site, I always have a spare DIY antenna in my van or under my operating desk.  Along with my portable multiband HF antenna, I also carry a "go-kit" with a HF transceiver, solar panels, deep cycle marine battery, an antenna "tuner", spare feed lines (usually 450 ohm ladder line), and a variety of 1:4 and 1:1 current baluns.  I've tried a few of the antennas described in this article and found them to be reasonably simple, portable, and

Bob Hajdak (N8QE) wraps up this 8 part series on the ARRL Field Day with one of the best reasons to join your fellow radio amateurs "in the field"--"It's blast!"  Granted, Field Day is supposed to be a test of our emergency communications preparedness, and it is for the most part. But there's nothing in the ARRL Field Day rules that outlaws fun, friendship, and, occasionally, excellent food prepared over a campfire or portable butane stove.  Even if you can't join a club in the field, take your station outside, erect a temporary antenna, position your solar panels, hook up a deep cycle marine battery, and get ready for a radio adventure. Enjoy the upcoming ARRL Field Day! Thanks to DXEngineering for an enjoyable and enlightening video series on Field Day. For the latest Amateur/Ham Radio ne

Here is part 7 of DXEngineering's series on the ARRL Field Day.  In this segment, George Proudfoot (K3GP) shows us another aspect of the annual ARRL event--How Field Day keeps us prepared for emergencies and natural disasters. Field Day hones our operating and technical skills by forcing us to use emergency power sources, making on-the-spot antennas, learning how to make repairs, and adapting to field operating conditions.
