Ham Radio: Simple DX antenna for 10 metres.

Image
The 10-meter Amateur Radio Band is getting more attention these days now that solar cycle 25 is favoring the upper HF bands. In this video from Tim (G5TM), we get all the information we need to design, build, test, and use this economical 10-meter halfwave vertical antenna. The antenna is easy-to-build, requires no radial wires, and offers good performance as a DX antenna.  The antenna is suitable for both home and portable use.

  Here's another great portable antenna idea from Australian radio amateur Peter Parker (VK3YE). In this video, Peter describes "a simple vertically polarized beam" for the 15 meter Ham Radio band (21 MHz.).  This antenna is suitable for both home and field use. If you can't see the video, please insert this title URL into your browser search box:  https://www.youtube.com/watch?v=Surn9tak4ao Here are some comments from Peter (VK3YE): Beams can be heavy and bulky so are rarely used by HF portable operators. But not this one! Described is a simple vertically polarised beam for 21 MHz. With a quick to rotate wire reflector and easily-fed off-centre driven element. Thanks to Nik VK3ZK for the test.

357: Ham Radio fun: ARRL Field Day '22-Antenna.

Image
The ARRL Field Day is set for 24-25 June 2023.  Thousands of radio amateur across the U.S. and Canada are expected to participate in this large emergency communications exercise and contest. All kinds of antennas will make their appearance, from the basic dipole to multielement yagi beams. Most of us radio amateurs will most likely with simple rigs and even simpler antennas. In the video, Alan (W2AEW) shows us how he operated in the 2022 edition of Field Day.  Alan's station and antenna system is simple, portable, and easy to set up and take down.

80 Meter NVIS Antenna.

Image
In this video, Tim Carter (W3ATB), shows us how to build and install a simple 80-meter NVIS antenna (Near Vertical Incidence Skywave). Tim takes you step by step through the entire process--no fluff, fancy drawings, or flowery commentary.  Just the basic setup and operational facts. If you can't see the video, please insert this title URL into your browser search box:  https://www.youtube.com/watch?v=3TF6WFoPsFw Here are some comments from Tim (W3ATB): " NVIS stands for Near Vertical Incidence Skywave.   It's a skywave radio-wave propagation path that provides usable signals in the medium distances range.   NVIS is typically used for communication ranges of from 50 to 600 miles.   When topographical features, such as mountainous terrain, are involved, the typical ground wave distance of 50 miles can be reduced to very short distances. A horizontally polarized antenna provides the best NVIS propagation. A wire half-wave dipole trimmed for the frequency of use is very effect

Unlocking the Secrets of The Half Square Antenna.

Window Screen Ground Plane Test.

Image
If you need an easy-to-install ground system for your 1/4 wave vertical HF antenna, try this intriguing idea from "Classic Clay Presents" (KO4MEX), Rather than using long lengths of wire, this ground system consists of a large window screen--something you can find at a hardware store or building supply outlet.  You roll up the screen and store it in your vehicle before going to the field for your next portable operation. According to this video, the window screen ground plane works well enough to make it a valuable antenna accessory. If you can't see the video, please insert this title URL into your browser search box:  https://www.youtube.com/watch?v=Kf3NOQQwYtU Here are some notes from the video: Here is my interpretation of using metal window screen as a ground plane. Wow i was impressed! Despite poor band conditions it seemed to work almost just as well as the long radials and is much quicker to set up. I will be testing it more in the near future when the bands are b

Amazing performance of ARRL 40-10 EFHW on WARC Bands

Image
According to Dave Casler (KE0OG), the recently introduced ARRL 40m-10m end fed halfwave antenna has some additional qualities for those who enjoy experimenting with antennas. With a few modifications, this antenna can be used on the WARC Bands without much loss in performance.  Dave discusses some of these alterations in the spirit of getting more from an antenna designed for only a few amateur radio frequencies. If you can't see the video, please insert this title URL into your browser search box:  https://www.youtube.com/watch?v=KUmHgf478q4 Here are some comments from Dave (KE0OG): We are going to respond to a comment, which suggests that we test it on all the bands.
