The Hustler 6ATV is an exceptionally well-made vertical antenna, but, in its original condition, doesn't cover the popular 12 and 17 meter amateur radio bands. In this video, K5ACL ("Signal Search") shows us how he modified the 6ATV to operate on 12 and 17 meters without affecting the other HF bands. All you have to do is follow K5ACL's step-by-step procedure and trim/adjust to obtain a low SWR.  The estimated cost of this modification is approximately $8.00 (USD).

Thanks to Adrian ("One Time Pad") for this excellent video tutorial on how to design and build a doublet antenna.  If you have doubts about your ability to make or erect this antenna, please ask for help from your local amateur radio club.  The project will go much safer and quicker with the help of friends. Adrian has supplied a full list of components and materials for this basic HF antenna: "Antenna Components: Copper wire for radiating element (I used multi –strand Flexweave) Ladder line/Open wire/Ribbon (I used 300Ω ribbon because its neater) x3 eye bolts with associated nuts as washers x1 straight wastewater pipe connector x2 access plugs for above wastewater pipe connector x2 wing nuts and bolts x2 Dog bone Isolators (to isolate end of each antenna leg) x1 spool Rosin core solder (i.e. solder with embedded flux) Cable

If you want a simple, effective, and inexpensive antenna for the 40 and 20 meter amateur radio bands, then this video by RC286 is for you.  This video documentary covers the theory, design, construction, and use of this two-band HF antenna.  Dipole antennas can do an excellent job if they are mounted high enough and clear from obstructions. Even if you can only support an inverted Vee dipole antenna on a single mast, you will still get good results.  Make one of these antennas for portable or emergency use.  This two band HF dipole antenna can also serve as a "backup antenna" in case your current antenna is disabled.

If you can't view this video, please insert this title URL into your browser search box: https://www.youtube.com/watch?v=39KyjSzw31I. For those of you who have some space in your backyard, a random loop antenna can offer some interesting possibilities.  When I was upgrading my new home in the Puna District of Hawaii Island a few years ago, I erected a 540-ft/164.53 meters horizontal loop on my property's spacious backyard, thanks to some 30-ft/9.146 meters Norfolk Pine Trees around the lot. The antenna generally followed the guidelines outlined in this video from Stan Gibilisco (W1GV). The key components of this experimental antenna were a balanced "tuner" (or a 4:1 balun/"tuner" combination), balanced feed line, and a good ground system for your station.  In my case, I used some speaker wire left over from a radio station news room renovation (I was working as a news announcer at the time for KHLO-AM 850/KKBG-FM (97.9 MHz), a roll of 300-ohm televisi

If you can't view this video, please insert this title URL into your browser search box: https://www.youtube.com/watch?v=84F4UgSWmQo. If you're a newly licensed Technician Class Amateur Radio operator, there's an exciting world of DX awaiting you in the 10-meter band.  Technicians can use a small segment of the band for SSB contacts as well as CW portions of the 80, 40, 15, and 10 meter amateur radio bands.  Although propagation doesn't always favor 10 meters, there are times when the band is open throughout the world.  Why not build a simple 10 meter dipole antenna to catch those openings? In this video, Randy Hall (K7AGE) shows you how to make an effective, inexpensive, and sturdy 10 meter dipole antenna.  Just follow Randy's step-by-step process, and you'll have a 10 meter dipole ready for use in only a few hours. Randy's instructions are clear and easily followed.  Good luck. For the latest Amateur Radio news and information, please visit these
