Can that loop be made at 1.5 or 2 meters in diameter? Would it make it a bit more "efficient" as a radiator? I want to make as big of a loop as I can, but 2 meters is about as large as I can go... I want to have it work on 30 meters. Thanks for your video and feedback... 73 de NW7US
@PA3DMI Another question or two: is the loop a directional antenna? Must you aim the antenna to your target? Also, for HF, do you want the antenna loop up vertically, or laying down horizontally? 73 de NW7US
My faraday loops have always been 1/5 D to load 50 ohms. Also try bending the Faraday loop into a flat triangle, so the bottom 1/3 is flat to the main loop.
Output is peaked with a couple of turns of wire and an LED.
The capacitor is an old 500pF one, I got it for a fair al long time ago. It's about 12 cm long and the platespacing is 3 mm so I can use it with about 100Watt otherwise it's sparking a lot :-)
@PA3DMI Thanks for the info. I don't think I'll be operating anywhere near 100 watts, but at least now I know what to use. Variable capacitors are very tricky to understand. I've got the tubing and wire set up, last step is the capacitor. Thanks!

@NW7US Hi Thomas, yep it is possible to make it larger but not very handy ... but the bigger the better.
My version works well on 30 although only 1 meter
Let me know.

@NW7US Hi again,
You can aim the antenna when vertically, if you lay the loop down I don't see any change.

What type of variable capacitor are you using?

Nice work! Very effective and very simple. I can't wait to start constructing mine =)

congrats for your loop ant.
I'm thinking to buy the MFJ and kick away the 25 meter random wire tuned by CG3000 auto-tuner on the base....
I wonder if the small 1 meter loop will be over the wire on 40meters....who knows...
