A thoroughly fascinating, informative video from Chris (K2CJB) on how to build and install a 6 meter "Squalo" Antenna.  The squalo antenna was a popular 2 meter mobile antenna for those using SSB on the 2 meter amateur radio band.  Chris has done a fine job of adapting the original design of Ernest Neijenhuis (PA3HCM) to this project. For detailed plans on this antennas, please visit Ernest's website at http://www.pa3hcm.nl/?p=312. The squalo antenna would be perfect 6 meter antenna for those living on a small urban lot.

If you can't see the video, please insert this title URL into your browser search box: https://www.youtube.com/watch?v=Wrfmmb-YNyI. This is post 2073 in a continuing series about ham radio antennas. In this well-paced video from Kevin Loughin (KB9RLW), we learn how to design, build, and test a simple 630 meter magloop antenna. This antenna can be used in deed-restricted housing (HOAs and CC&Rs) as well as in portable and field operations. Kevin has done an excellent job of showing how this simple antenna can be made.

If you can't see the video, please insert this title URL into your browser search box: https://www.youtube.com/watch?v=6hq7HAOYjZA. Here's another great, inexpensive end fed antenna you can build for both portable and home operations.  WI9LL demonstrates just how easy it is to make one of these handy HF antennas. "I built this antenna specifically for low wattage QRP use to be compact and inexpensive. It utilizes a 9:1 unun wrapped on a T106-2 toroid and minimal hardware to be lightweight. Here is a video of me testing the antenna with WSPR mode. The results surprised me: https://youtu.be/2-AwzPk1g4Q " ---------------------- For the latest Amateur/Ham Radio news and information, please visit these websites: http://www.HawaiiARRL.info. http://www.arrl.org. http://www.blubrry.com/arrlaudionews/ http://www.hamradioupdate.com. http://www.southgatearc.org. https://oahuarrlnews.wordpress.com. https://hamradiohawaii.wordpress.com. https://bigisl

Ham Radio - My second HF antenna. A stealth end fed wire for 80 - 10 m...

If you can't see the video, please insert this title URL into your browser search box: https://www.youtube.com/watch?v=oMchB-bML98.  This is post number 2071. This video came from a need to design, build, test, and use a backup HF antenna that would be reasonably effective, while remaining undetected by neighbors. Kevin Loughin (KB9RLW) decided to build a simple end-fed wire antenna that would be attached to his roof and could cover 80 through 10 meters. Kevin takes you step-by-step through the design, assembly, and tuning procedures.  Be careful with this antenna, since high voltages may be present at the end point of the antenna.  Be sure to use a balun, antenna "tuner", and a good counterpoise with this antenna system. The length of this antenna is 58-feet/17.68 meters, with the counterpose measuring 40-feet/12.19 meters. If you live in deed-restricted housing, this antenna may get you on the air without attracting the attention of your neighbors. -------
