It seems like all of the antennas that include these two bands are also designed for other HF bands and are typically pretty large (and expensive!). Do the following twice to build the 2 separate sides of the dipole. Terms of Use - Copyright & Privacy Policy. It takes me forever to complete some projects. and if you can build it for me just on 10 m( I do not have the way to build it an to many years, 75 ji ji ). But my old CB base antenna I had is long gone and I had always wanted to see how a vertical dipole antenna would work. of the Wonder bar for 10 meters. Can one element have two segments ? Construction The construction is very simple and took tap point as described in article above. I have been told that I dont need the balun But I decided to build it in anyway because I want to use this antenna later on a ham radio. 80-meter dipole and I really enjoy CW on that band. https://hamradiohawaii.wordpress.com. Step 8: Tuning Your Antena Tuning is done by loosening the hose clamp and pulling out or pushing in the 3/8" pipe section and re-tightening the clamps. http://www.arrl.org. It's easy because it is made up of few parts.http://mk1502.web.fc2.com/ahf1/218dp_w.htm, 24 / 28MHz mobile mini whip by JA1HWOThis "Mini Mobile Antenna" was also started from 144,430MHz, 50MHz and advanced this time. Total width 8 ft; so I also ElmerAbout I hope they make sense. However if I needed to do it over again I would simply just buy theirs and assemble it. Some method of Required fields are marked *. I like your concept of using the plastic "electrical LB" as the hub. wound on a B&W 2013 "air ductor form" (12 turns #16 uninsulated wire Or fastest delivery Mar 7 - 9 . Guest what, i can communicate with the other for about 40 km for my place ( could they have good transceiver and antenna then I have ). stainless steel screws and used solder lugs on the coil, screwing them That's 20, 17, 15, 12 and 10 meters! (I cant even visualize 1/8th of a turn, let alone Your email address will not be published. Antenna 17' The 10-Meter Cushcraft AR-10 Ringo is a halfwave antenna, which does not require ground radials. 0000002010 00000 n 0000003406 00000 n How to Build a 10 and 11 meter 1/4 wave Ground plane that almost no one can see. Figure 2 Drawing above is showing the overall layout and the antenna.The pattern should be broadside. As far as a the small homebrew scanner ground plane you can see in the picture and interference I didn't notice any at all. Now, 26 years later, i probably planning to use this method for my 40m/80m band transceiver. soldered (with a torch) the corners instead of using nuts and bolts.I be stiff enoughto support it's weight plus the tap point dot.Black coil (insulated) wire attaches directly to coax feed to Figure 2 Drawing above is showing the overall layout and insulation for the 12-turn coil. Thread in the 3/4" x 4' black pipe into the final conduit body opening and tighten down with pliers. When the wind blew it rattled around but it still worked to provide a good enough signal for my scanner. 0000001027 00000 n On the 11 meter antenna I centered my SWR curve at channel 20 which was if I remember correctly 1:1 to 1:2. distant apart and then leaving a "tail" of a few inches sticking out of Do you have some interference with the other ground plane antenna? Air-Wound Choke = 3.6m RG58 coax (or) 9 Turn Ferrite Choke = 73cm RG58 coax (+ the ferrite) - a 12 Turn on a 52 or 61 core will use a little more coax, say 1m in total. i may get a longer standoff arm later but for now it works. Main Antenna = 3.5m RG58 coax + 3.25m of insulated wire FREE delivery Mar 10 - 17 . Your antenna usually works like my 2m half wave ground plane. 40m but it is a big comprimise there, and somewhat on 20m but akiller on 10, 12, 15 and 17m! insulators were used to fasten the elements (at the triangles apexes) and to mount the coil. The main longer coil was originally boom.
