If you're having trouble viewing this video, please insert this title link into your browser search box" https://youtu.be/CbQwLPVmG70.  In this video, Brian Downs show us how to use Ham Stick style Antennas in a vertical configuration. This arrangement could come in handy for portable operations or for areas with restricted antenna space.  Brian uses a set of 20 meter Ham Sticks to make the vertical dipole.  You can get 20 meter to 10 meter coverage if you feed the antenna with 450 ohm ladder line, use a 4:1 balun, and a short length of 50 ohm coaxial cable to connect the balanced line and balun combination to your antenna transmatch (i.e. "tuner").  For the latest Amateur Radio news and events, please check out the blog sidebars.  These news feeds are updated daily.  You can follow our blog community with a free email subscription or by tapping into the blog RSS feed.  Thanks for joining us today!  Aloha es 73 de Russ (KH6JRM).

Simple Ham Radio Antennas--The Fence Dipole (FFD). Post #718

The Fence Dipole (FFD): A Quick, Easy, and Inexpensive Multiband Antenna. Post #718. (http://www.eham.net/articles/35785. Accessed on 16 March 2016, 23:46 hrs, UTC. Author:  Howard Groverman (W6HDG). Please click on title link to read the full story. Comment: If you're living in a HOA or CC&R environment or just lack enough space to build numerous antennas, then the Fence Dipole (FFD) from Howard Groverman (W6HDG) may be the solution to your antenna problem.  This variant of the Fan Dipole is "quick, easy, and inexpensive" to design, build, and use.  Howard provides all of the illustrations, photos, and antenna data you need to get started. This would make a perfect weekend project with both at-home and portable use applications.  Most of the materials can be found at the nearest hardware store or building supply outlet.

Simple Ham Radio Antennas--The Windom Antenna. Post #717.

The Windom Antenna (http://www.packetradio.com/windom.htm). Accessed on 16 March 2016, 05:46 hours. Author:  C.E. "Buck" Rogers (K4ABT). Please click title link to read the full article. Comment: If you want to experiment with dipole antennas, why not try designing, building, and using the classic "Windom" Antenna?  This antenna dates back to 1923 when William Litell Everitt began working with simple off center fed dipoles.  In the intervening years, the off center fed dipole, used with either ladder line or coaxial cable, has become a basic multiband antenna used around the world. C.E. "Buck" Rogers (K4ABT) has written an exhaustive study of this classic wire antenna, tracing its history back to the early 1920s and bringing the design up to date for 2016. Rogers illustrates some of the basic OCF designs with a variety of graphs, SWR plots, and patterns.  He provides essential dimensions for wire length, antenna feed options, and suitable balu

If you're having trouble viewing this video, please insert this title link into your browser search box: https://youtu.be/-PZN7InAUug.  Here's an interesting portable antenna from North Huron Communications.  According to the video, the 10-80P is an HF portable antenna system usable in the frequency range of 3.5 MHz to 30 MHz. The system can be used with any HF transceiver and handles up to 250 watts PEP.  The antenna kit comes with brass clip sections, tripod bracket, counterpoise wire, coil, and other accessories.  This appears to be a quality product that could be used for both home and portable use.  For the latest Amateur Radio news and events, please check out the blog sidebars.  These news feeds are updated daily.  Thanks for joining us today!  Aloha es 73 de Russ (KH6JRM).  This is post #716. 

Simple Ham Radio Antennas--Ham Radio - Using Fiberglass Poles for HF Portable Operation

Image
If you're having trouble viewing this video, please insert this title link into your browser search box: https://youtu.be/GMxZWvGzfIE.  Nicely done video by Tracy (VK3TWM) on how to use telescoping fiberglass poles for portable antenna supports.  These poles are available from Jackite, MFJ, and a few other outlets.  In this video, Tracy put the fed end of the antenna up high on the pole due to past success with this method.  Others may prefer attaching the feed line at the base of the fiberglass pole. These collapsable poles can be stored in your vehicle or home shack for emergency or portable use.  For the latest Amateur Radio news and events, please check out the blog sidebars.

If you're having trouble viewing this video, please insert this title link into your browser search box: https://youtu.be/RIvW9f--JOI.  Here's an interesting challenge from Peter Parker (VK3YE).  Can you unpack and set up a portable vertical antenna in 3 minutes or less?  The key to this solution is having a telescoping 9 meter mast, 10 meters of wire, a decent ground radial or counterpoise system, and a L-match antenna coupler (tuner).  This quick set-up antenna would be perfect for portable or emergency operations.  Lots of good ideas here!  For the latest Amateur Radio news and events, please check out the blog sidebars.  These news feeds are updated daily.

Simple Ham Radio Antennas--Dipole Center-Loaded with Ladder Line. Post #713.

If you're having trouble viewing this video, please insert this title link into your browser search box: https://youtu.be/FfLIL9yjy0A.  One of the simplest, effective antennas you can make is the center-loaded dipole fed with 50 ohm ( RG-58 , RG-8 , RG-8X) cable or with 75 ohm ( RG-59 or RG-6 ) cable.  This antenna is cut for the frequency band of your choice and is most effective and efficient as a monoband antenna.  Multiband operation can be obtained by using 300 ohm television twin lead or 450 ohm ladder line connected to a balanced tuner or a balun to tuner combination.   Stan Gibilisco (W1GV) does an excellent job of explaining the theory, design, and construction of this classic half wavelength dipole antenna , which can be used for a single band (coax fed into your transceiver) or multiband purposes with ladder line into a tuner.  Most of the materials for this basic antenna can be bought at the nearest hardware store or home building supply outlet.  Placed as high
