If you can't see the video, please insert this title URL into your browser search box; https://www.youtube.com/watch?v=sli_OXoOugM This post 2553 in a continuing series of simple ham radio antennas. This is part two of "The Doublet Antenna Experiment" from Kevin Loughnin (KB9RLW). In part one, Kevin designs, builds, and tests his new HF doublet antenna. In part two, Kevin takes the antenna to the "field" and begins a few QSOs.  The results are quite good. Here are some comments from Kevin: Thoughts and observations after using the doublet for awhile. Plus a couple of QSOs, one of which was stellar.

Ham Radio-The Doublet. An old but good multiband single dipole antenna

If you can't see the video, please insert this title URL into your browser search box: https://www.youtube.com/watch?v=tA4loiihJwE This is post 2552 in a continuing series of simple ham radio antennas. If you need a single antenna to cover several HF amateur radio bands, then you might consider building the "classic" doublet antenna. In this two-part series from Kevin Loughin (KB9RLW), we design, build, test, and use this versatile HF antenna. Here are few comments from Kevin: One of the antennas I've wanted to play with for awhile. In this video, we look at the antenna and it's design, and then my build of the antenna. In part 2, we'll look at it's performance and try it out on the air.

If you can't see the video, please insert this title URL into your browser search box: https://www.youtube.com/watch?v=RcO5WAiksNI This is post 2551 in a continuing series of simple ham radio antennas. Thanks to Dave Turlock (KG0ZZ) for this easy-to-make 2m/70cm vertical dipole antenna.  As Dave suggests, this antenna is perfect for home or field use. Here are some comments from Dave: A simple ham radio 2 meter and 70 cm antenna for fixed or portable use. For details: http://www.amateurradio.bz/2m-70cm_ve... ----- Thanks for joining us today.

If you can't see the video, please insert this title URL into your browser search box: https://www.youtube.com/watch?v=CoNYdmRagbs This is post 2550 in a continuing series of simple ham radio antennas. If you need a compact, nearly invisible VHF/UHF antenna for your ham shack, then try this "Flower Pot" design from Mike (M0MSN). Mike calls this antenna the "perfect stealth antenna" for 2m/70cm. Mike does an excellent job of taking us through the design, construction, and testing process for this remarkably simple antenna. Here are some of Mike's comments: HAM Radio, Antenna, the Flower Pot Antenna, a Stealth Antenna that you can hide in a plant pot and cover with plastic flowers and leaves, No one would ever know........Just 1.2 metres high and perfect for the patio or balcony ......

You don't need a pile of money to make effective, inexpensive HF antennas for both home and field use. Just follow the suggestions from "Ham Radio In Action" to see how a homebrew HF antenna can deliver great coverage at a modest cost. Here are some comments from the author: I made a NorCal doublet HF antenna from scrap computer cable using this plan: http://norcalqrp.org/norcaldoublet.htm ​ I set it up in a park with my Xeigu X-5105 radio and made some contacts. ----- Thanks for joining us today.  Aloha es 73 de Russ (KH6JRM).  

HAM RADIO: Your First HF Antenna

If you can't see the video, please insert this title URL into your browser search box: https://www.youtube.com/watch?v=bDo6E27Wnd4 This is post 2548 in a continuing series of simple ham radio antennas. Most radio amateurs can remember their first HF antenna with a mixture of elation and disappointment. My first HF antenna was a low-level 40 meter dipole which gave me many contacts, despite its poor design and meager range (mostly NVIS). From that first experiment, I went on to build better antennas which left my original antenna rolled up in the garage. In this well-made video from Tim (G5TM), we see how newly licensed radio amateurs can find their ideal first HF antenna with a minimum of time and effort. Tim does an excellent job of explaining the pros and cons of verticals, dipoles, and end-fed wires. Antenna building is educational and fun, especially when you can make most wire antennas from simple, inexpensive materials. Catch Tim's enthusiasm and build your own antenna to

Best HF Antenna: The Monopole Dipole

If you can't see the video, please insert this title URL into your browser search box: https://www.youtube.com/watch?v=RbON7DAqz9M This is post 2547 in a continuing series of simple ham radio antennas. Thanks to Lucien (DH7LM) for this exceptionally well-presented tutorial on one of the best HF antennas available to radio amateurs--the monoband HF dipole. This antenna is simple, inexpensive, and suitable for both at home operation and in "field" activities. Here are some general remarks from Lucien: Overtime, I came to realize how important radiation patterns are - and how the classic monoband dipole shines here. Especially if you are a beginning ham radio operator, give it a shot before you try complicated designs! ----- Thanks for joining us today. Aloha es 73 de Russ (KH6JRM).
