If you can't see the video, please insert this title URL into your browser search box: https://www.youtube.com/watch?v=JPg7mug_WnY.  This is post 2107 in a continuing series of simple ham radio antennas. If you'd like to try some antenna experiments, then this video from the Mitsubishi Electric Channel will prove interesting. According to the presentation, "Our seawater antenna, named "SeaAerial," is changing the way we communicate. Rather than using metal, we've developed a more sustainable and flexible approach, keeping you connected to the things that matter most." Although I've never used this type of antenna, the idea seems intriguing.  At least the basic antenna material (i.e. salt water) should be cheap if you live near the seashore.  Why not build this seawater antenna and see how it works?  This could be a fun project. ------------ For the latest Amateur/Ham news and information, please visit these web sites: http://www.Ha

If you want a 160 meter antenna that "really gets out", try this balloon antenna launched by AK7AZ during the 2011 CQWWDX-SSB Contest. In this video, N7SCL takes us from unpacking the antenna package to the final assembly and launch of this "monster" vertical antenna. A grand time was had by all.  I need these guys for my next ARRL Field Day experience!.

Ham Radio - 80 160 meter magnetic loop transmitting antenna

If you can't see the video, please insert this title URL into your browser search box: https://www.youtube.com/watch?v=s3oP6VAG3gs. This post 2104 in a continuing series of simple ham radio antennas. If you want to work stations on 80 and 160 meters, but have little space to erect an antenna, try this fairly simple magnetic loop antenna from Kevin Loughin (KB9RLW). Just follow Kevin's simple instructions: "This is my 6 foot diameter magloop for 80 and 160 meters. I create a two turn outer loop to get down to 160 and it works very well. I checked in to a local 160 meter net and 4 out of 5 stations could hear me. Pretty neat for a 6ft antenna! There have been a few questions about the capacitor I used. Measured on my old Heathkit RLC bridge, it looks to be around 20-700pf with about 1mm plate spacing. I've pushed it to 40 watts without an arc. I also built a mini loop out of junkbox parts for fun. It's 1 foot square and works really well. https://

Slot antenna from a parabolic dish for 2m/70cm use. Post 2103

If you have an old satellite parabolic dish antenna, you may want to convert it for 2 meter and 70 cm use. James Sanders (AG6IF) shows you how to make the easy conversion in this video.  James says this alteration yields a cheap, easy to operate, and "stealthy antenna" for deed-restricted housing.

Making and Using a Simple 40-m Dipole (#86)

If you can't see the video, please insert this title URL into your browser search box: https://www.youtube.com/watch?v=gfLUrVnnQUI. This is post 2102 in a continuing series of simple ham radio antennas. Thanks to Dave Casler (KE0OG) for this nicely done tutorial on how to make a 40 meter dipole antenna out of parts you may have around your home. There's no need to spend a lot of money on an antenna if you're willing to use what's available locally.  Antenna experimentation is both fun and educational.  Put those antenna formulas to work on a dipole you made yourself. Here are some observations from Dave as he makes this homebrew 40 meter dipole antenna: "I'm often asked how to make a dipole. In this video I use materials on hand to build a 40-meter amateur radio dipole. I hung it on the antenna test rig I built this past week, and it works great! Lots of work, though. Although dipoles are available for far less than $100, I made this one for zero!&qu

Cheap HF Homebrew 40m 20m 15m Vertical antenna.

If you can't see the video, please insert this title URL into your browser search box: https://www.youtube.com/watch?v=mahLAFvCbfc. This is post 2101 in a continuing series of simple ham radio antennas. Many thanks to Mike Hannah (W9XAX) for this ultra simple, inexpensive, and efficient vertical antenna. The antenna covers the 40 meter, 20 meter, and 15 meter amateur/ham radio bands with commonly available materials. Mike takes you step-by-step throught the design and building process. Here are his remarks concerning this antenna: "This is a multi-element vertical HF antenna I designed. I have 2 elements on it which will tune up on 40m, 20m, and 15m without a tuner and most others with a tuner. The goal of this project was to be cheap, yet tuned. It accomplished that goal. Hope you enjoy and leave some feedback!!! 73! Subscribe!!!" ----------------------------------- For the latest Amateur/Ham Radio news and information, please visit these websites: ht
