That is awesome Pavol, sure likes 20 meters that is for sure. Even 17 is a nice swr for sure and decent bandwidth when tuned. Cheers Fred
I have found the exact same capacitor as yours (320+380 pF) on eBay for $20 in Bulgaria. I've bought two and I will make the same antenna!
That variable capacitor has two major sections of different sizes.
Hi Paul,
I made a couple Magnetic Loops. My best works for 15 threw 40 meters.
Very nice job! Antenna is great and radio is great too! Thank you for this video.
Very good job. My next antenna build is a magnetic loop in the same frequency range as yours, I'm planning on using a capacitor out of a full power tuner. I have an old Amp Supply AT-1200, I also have a 10-foot 3/4-inch copper tube, since I already have the copper, I will go with it. I's nice to have an analyzer built into the radio, I use my G90 in the same manner. 73's🎙KD9OAM🎧
looks great, would love to get a hold of the parts to make one for my X5105. may have to do some saving up for this
Hello, great video of your Magnetic Loop. I have a question, how long is your thick coaxial cable that you made as a big ring? 73Jörg
I am building a very similar antenna, and will watch your progress with interest.
Wormant is in Micro Bandas youtube page
Most interesting project. Amazing results. And quality video.
Paul, I love the video. I have a Xiegu G1M SDR QRP. I will build a similar antenna (waiting on a variable capacitor from China - similar to yours - 2 ganged 350 pf).
Good ideas. Got a little seasick watching the moving camera. I made videos for 30 years. The point of the motion camera is for the subjects to move NOT THE CAMERA. Devise a homebrew tripod for your camera, or buy one. The PVC mount seemed to have changed shape from the start to the end of the video. These are wonderful little antennas, and the ideas in this video are very solid. I look forward to making one.
What confuses me is that the loops are made of shielded coax which blocks signals. Why isn't it better to use exposed copper?
Is your antenna a resonant shielded frame? In the center of the loop, the screen should be cut, in the same place, the connection loop is connected in the form of a small circle.
Excellent! I might try to build one! Thanks and 73 de K2CJB
I am disabled and could not build such an antenna. Would you be able to build one for me or recommend a commercial antenna of similar dimensions. Cost is not terribly important. Thank you, Mike, N0WDM
Hello Paul, very interesting built of a MLA. Have been experimenting myself but have a larger size loop. This one is smaller but seems to be working well. Have 2 questions: Don't you have problems with tuning, I'm not shure your capacitor has reduction? And question 2 is: Could you tell us the length of the coax you used for the large and the small loop. I like the way you routed the coax through the tube, never thought of that. 73, Bas PE4BAS
Hey dr op. What RG type cable is the main loop made of? And which scheme did you use for connecting the RG58 small loop at the ring/shielding? Thx es mny 73.
