Please click title link or insert title URL to read the full report and to see the accompanying video. Comment: Here's another idea for a portable vertical antenna which is easily made, highly portable, and inexpensive. In this post, Melchlor Varela (EA4FRB) creates a simple, easily assembled HF vertical antenna that covers the 20, 30, and 40 meter amateur radio bands using a fishing pole mast, some wire, and a homemade coil which is tapped by using alligator clips.  The antenna is based on a design by EB5EKT. This antenna would make a perfect portable or emergency antenna.  The accompanying video shows you how to make this simple, effective vertical antenna.

If you're interested in pedestrian mobile operations, this compact antenna from Peter Parker (VK3YE) will help you realize that goal.  Peter's antenna covers from 7 MHz to 28 MHz and is patterned after the once-popular "Miracle Whip" antenna. You could also use this antenna for emergency operations or even in deed-restricted housing (HOA/CC&R).

If you're having trouble viewing this video, please insert this title link into your browser search box: https://www.youtube.com/watch?v=dCXdCLpnju0.  This is post #895 in a continuing series of articles on simple ham radio antennas. In this video from Peter Parker (VK3YE), we get an idea of how simple telescoping, carbon fiber/fiberglass poles can be used to support verticals, slopers, and dipoles in portable or emergency operations. Peter uses poles measuring approximately 5.4 meters/17.7 feet long for his vertical antenna supports.  Poles in a variety of lengths can be ordered from a number of vendors, including a telescoping fiberglass mast from MFJ that measures 33-feet/10.06 meters long.  I use these longer lengths for supporting verticals and loops at my QTH.  The shorter lengths recommended by Peter are idea for portable use.

If you're having trouble viewing this video, please insert this title link into your browser search box: https://www.youtube.com/watch?v=Rui4Q8IwB8k.  Another well-produced, easily understandable video from Peter Parker (VK3YE). In this video, Peter shows us just how easy it is to build, erect, and use a vertically polarized Moxon Rectangle Antenna for portable QRP operations. Peter's antenna was designed for 20 meters and it does an excellent job at this seaside location.  Of course, the ocean water in front of the antenna helps a lot in getting a good signal launch from shore.
