Nice video *smiles* I usually build one of those into pvc pipe, with end caps. If you install a pocket radio variable tuning capacitor into one of the end caps you can keep the whole unit slender enough to EDC in a bag with the radio and it will be very sturdy. Longer is better for the ferrite rod and thicker is better for the litz wire windings. Any kind of stranded insulated wire or magnet wire works pretty well though. AC runs on the surface of the wire, that's why stranded is better and litz is best.
Used to use one of these while stationed at Greenland, back in the '80s, to tune-in LW rock stations from the Beeb, and what eventually became Atlantic 252, from Ireland, on a cheap Blaupunkt FM-LW/MW/SW that I won in a card game. The gent who lost the radio and "external boost" had been written up for having wire strung up all over one corner of his barracks, and solved his radio dilemma with the tunable ferrite "inductance improvement device". In 50 years, someone will be trying to unbrick an antique Linksys WRT-54-G WIFI Router, and rediscover the foil waveguide hack, and the Tomato software upgrade, then come across this "old tech HD video" while searching for "antique antenna booster".
+AMStationEngineer Tim, what a cool memory and I appreciate you sharing it. LOL on your second paragraph. Hope you're doing well and thanks again for viewing. Best, Don
You can wind an extra coil over it and use it with your long wire antenna to hear distant AM or long wave stations. Just make sure that you use a RF ground rod with the connection.
Interesting video--thanks for sharing! I remember as a youngster using a AM transmitter kit I assembled, which had a coil wound on a form. While it was off, I noticed that when I rotated the tuning condenser while next to a AM radio tuned to static, I would hear radio stations with listenable sound come in fairly clear. I noticed that AM 550 is used by radio stations in Pinehurst and Statesville, and yet another radio station in Virginia. It's assumed that the wattage of these AM transmitters is sufficiently low, and the distances far enough, so as to not interfere with each other even at night.
+Chet Pomeroy Your AM Kit had to be fun. I had a few of them myself. My database shows Pinehurst at 1 kW Day and 0.26 Night, while Statesville is Directional at 0.5 kW Day and only 0.53 kW at Night. I didn’t study or review the Antenna pattern for Statesville. Have you looked at it? Best, Don
@RestoreOldRadios--According to what I found on the FCC AM database, WAME Statesville is only authorized for only 0.053 kW (53 watts?) at night. WIOZ Pinehurst is allowed 0.26 kW after sunset. I haven't looked at their respective day/night antenna patterns, but I'm willing to bet that the FCC is watching both of them like a hawk (like everybody else in the business)!
Great video, I aim to build one. As an upgrade, I plan to add a simple Q multplier I used in my youth - two coils added over the ferrite with a couple of turns etch, one in the emitter lead and one in the collector of a crude common base transistor amp, adjusted by varying rail voltage.
A superb loop aerial device you've constructed Don. It works very effectively, and it is far more compact than one I've almost completed constructing. Hopefully, my loop aerial will be uploaded onto You Tube within the next two weeks. When you have seen the video, I'd love to read what you think of it. Cheers, Phil.
+SteelCity321PB Phil, I can't wait to see your loop antenna. I know it will be top notch! I put this together in a few minutes and hope to clean it up later and rewind the inductor with litz wire to improve the "Q"; I couldn't find it the day I was messing around in the shop. I'll be eagerly watching for your video. Best, Don
Thank you for this video! As a beginner in radio stuff, I'd like to know what the best way is to make a better version of this booster. I mean, does it depend on the length or diameter of the ferrite rod; or the number of coils; or the capacity of the capacitor - the more the better? I have no idea.
I've built a tunable loop antenna but it's rather too large to look like anything but an eyesore inside the house. That looks like something I'd rather have for indoors instead of in the garage/workshop though I think I'd still try to find a small elongated box to put it in. Cool job, Don! Take care, Gary
Not that I am aware of unless it would be inside one of the old solid state radios around the house here or out in the garage. Take care, Gary P.S. Saw that Zenith cabinet last night and it's looking nice stripped down. Sure it has a few issues but I'm also sure you can make it look in tip top shape again. I have an RCA 5T tombstone that someone varnished and varnished over top of missing veneer and that's over a weak piece of grill work. I dread trying to clean that mess up but I'll try to be extra careful when I do. Right now I'm working on an RCA 56X tabletop. Take care, Gary

What type of ferrite material is it and what’s the diameter of the ferrite rod? Using Litz wire improves the ‘Q’ vs. stranded 22 to 24 AWG.

Probably not a big difference. I have the same loop and I would have to say from what I can recall, the reception using the ferrite rod antenna was very close to the loop. Best, Don
Can you please show me open winding. I might have not got what you said and i tried winding upto quarter of an inch on both sides. But didn't worked out.
Radio Frequency energy being broadcast by a transmitter just LOVES ferrite. RF waves will actually bend to go to the ferrite instead of just passing by. An inductor coil would on wood or plastic is no more sensitive than a coil with an air core....actually a little worse due to losses into the coil form. Ferrite is like a magnet for radio waves. The longer the rod, the more of the RF that is passing by can be attracted.
