The UV5R series of VHF/UHF transceivers from the Peoples Republic of China are popular, inexpensive radios for portable or casual operations.  Like many HTs sold these days, the antenna supplied with the radios leave much to be desired. In this well-paced video from Tony Kiser, we see how the UV5R's performance can be enhanced by simply changing the antenna to a more efficient design. If you plan to use the UV5R at your home station, you may want to mount a homemade J-Pole antenna outside your shack.  Be sure to choose a good coaxial cable to feed the antenna--something along the lines of LMR-400. ------------------------- 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://w

If you're handy with a few common tools and willing to experiment with surplus electronic parts, then this homebrewed VHF UHF antenna from "SurvivalComms" may interest you. This antenna project is cheap and uses locally available materials. According to "SurvivalComms", the antenna design, building, and testing were fairly easy.  Readily available parts made the project simple and easy: "Re-purposing / re-banding a cellular/PCS antenna into a dual band VHF UHF antenna. Items used are items from the "dollar box" at a hamfest tailgate and everyday hardware. Electronic surplus can be your friend !" --------------------------------- 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/arrlau

If you can't see the video, please insert this URL title link into your browser search box: https://www.youtube.com/watch?v=oPgKZUTIXp8. Most radio amateurs have heard about the "Inverted V" antenna as a way of getting almost all of the dipole antenna's advantages in a smaller space. What happens if we reverse the Inverted V and transform it into a "L" antenna?  In this well-paced and easily understood video, Johnny (W5KV) uses some easily available parts from MFJ, Buddipole, and Wolf River Coils to make an efficient portable antenna that takes up little space.  The finished product can be used for both portable and home-based operations. Here's a list of the materials used for this antenna project: MFJ-1979: https://amzn.to/2ryHCTe Wolf-River Coil: https://www.wolfrivercoils.com/ Buddipole Versatee: https://www.buddipole.com/versatee.html Buddipole Choke Balun: https://www.buddipole.com/chokebalun....

ARRL opposes cuts in 3.3-3.5 GHz Amateur Radio Allocation. Post 2065.

ARRL opposes cuts in 3.3-3.5 GHz Amateur Radio Allocation Source:   https://mail.google.com/mail/u/0/#inbox/FMfcgxwGBwSfmscscvqBrvfTVXwXdGbX Accessed on 27 November 2019, 0545 UTC, Post 2065. Author:  HQ ARRL, 225 Main Street, Newington, CT, 06111. Summary: Although this site discusses antenna issues, I sometimes depart from that activity to focus on events that impact Amateur/Ham Radio as a whole. Such is the case for my post number 2065.  The United States Federal Communications Commission is considering cutting back Amateur/Ham Radio allocations between 3.3 and 3.5 GHz to make room for commercial mobile services. This group of frequencies will have a significant impact on Amateur/Ham Radio satellites and experimental point-to-point communications.  The American Radio Relay League (ARRL) is asking the FCC to reconsider its Notice of Proposed Rulemaking (NPRM).
