Installing a G5RV Inverted V Antenna for HF use on a Fishing Pole. Post #1333..

If you can't view this video, please insert this title URL into your browser search box: https://www.youtube.com/watch?v=t6vI4nZMemM. The G5RV antenna is based on a design from Louis Varney (G5RV)(SK).  Originally, the antenna was made as a 3/2 wavelength antenna for the 20 meter band.  Over the years,  radio amateurs have modified the feed arrangement to allow operation on several bands, including 40, 20, and 10 meters.  Used with balanced feed line a 4:1 current balun, and a sturdy antenna transmatch (i.e. "tuner"), the G5RV can work other bands such as 15 meters. In this video, "kloxieman" shows us how he installed the G5RV as an inverted V using a 30-ft/9.146 meters fishing pole as the support structure.  His use of a balanced feed line, a current balun, and an antenna "tuner" gives this G5RV excellent performance on the 40, 20, and 10 meter bands.

If you can't view this video, please insert this title URL into your browser search box: https://www.youtube.com/watch?v=fvY6CxYNvhY. 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).

If you can't view this video, please insert this title URL into your browser search box: https://www.youtube.com/watch?v=vAYbkVhsSBY. 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

Building a dipole for 40 and 20 meters. Post #1329

If you can't view this video, please insert this title URL into your browser search box: https://youtube.com/watch?v=RVKRnQmrx3k. 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.
