C.Crane Twin Coil Ferrite AM Antenna | Full Review & Demo! 

lol. Small world! I just unpacked your 'Justice AM Antenna' about 10 minutes before I read your post. Bought it (hardly used) on eBay for half price of what a new one cost. Couldn't pass it up. Looking forward to using it!

Hello , I have come across a mint Justice unit at half the price. Is the Justice unit identical in specs to the C Crane unit ?

That’s awesome!!! It’s sad they seem no longer available... what happened? I wish I could get one...

@@scottbelcher9026 I'm unsure. I cut ties with them approx 20 years ago, and run our own company now, specializing in different technology. Great antenna. I have serial # 1. I have serial # 1 of all the radios, antennas and gadgets I designed back then. It was one of my demands.. I even have CCRadio serial #1, because I was the designer and engineer of that radio.. Heck I have about 15 different serial #1 products at least. haha.. have a good day.

@@chancha807 The Justice one is better, cause it has my name on it. lol. The one you have is a bit rarer.. When I cut ties with them, I requested they remove my name off of their products for marketing. Have a good day! The very rare ones, are the in-house built small production ones.. Production built a lot of them by hand back then. Good luck!

I love using it with my PL-360: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-KKc0niJjLDM.html

You're Welcome jesse. A step above the small passive loops.

Thank you Grayman423, I appreciate the comment.

You're Welcome Toney, you would do the same for someone else :) this is an awesome antenna for experimenting.

I did some videos with this paired to a Tecsun PL-360 ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-KKc0niJjLDM.html ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-ETCUUZO7Ka0.html . I too am looking forward to the 368.

You're Welcome Josh, I am sure you would do the same for others :)

This will be used for your MW DXing. It is superior to loops, and wires. I love it.

Brians Mac select a tennas are good, classy looking,

I know Im asking the wrong place but does someone know a way to log back into an instagram account?? I somehow forgot the login password. I love any assistance you can offer me!

@Carl Damien Instablaster =)

@Arthur Layne i really appreciate your reply. I found the site thru google and Im waiting for the hacking stuff atm. Takes a while so I will reply here later when my account password hopefully is recovered.

@Arthur Layne It did the trick and I actually got access to my account again. I'm so happy:D Thanks so much, you really help me out :D

@Carl Damien Glad I could help =)

They are an awesome company.

Yes, that yellow patch cable is a simple mono to mono 1/8" . Used with modular audio synths.

Done: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-KKc0niJjLDM.html

Will see, the passive loop is good, but the Twin has a lot more gain. Daytime use is the best. I also like moving the element and not the radio for tuning in and nulling out stations. Very handy.

I used it with a Tivdio V-115: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-XAglosoNJOA.html , I also showed a lot of gain differences with the Tecsun PL-360: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-KKc0niJjLDM.html

I wonder if it would work with the er200?

@@rickyhouchens9955 sure it will. Any AM radio with a built in ferrite antenna or an external AM antenna jack.

Awesome, thanks for the feedback. I plan on purchasing the new Tecsun shortwave radios when they become available.

Please in hindi

Glad to have you over at Discord. The Twin Coil will help your 310ET during the day for sure. It is an investment. If you only have the 310ET I would recommend picking up the Terk AM Passive loop. It is a nice rig, for a decent price.

@@todderbert, appreciate the prompt reply and feedback. I have already ordered for an AN 200 MW loop antenna by Tecsun. Along with radio, I had also purchased the AN 48x active loop antenna (Tecsun). After a bit of experimentation with it I observed a marginal improvement in SW reception (sometimes) but it's small ferrite core antenna is useless for MW reception.

@@ennemm9265 You can see more of the Twin Coil in action with a Tecsun PL-360: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-KKc0niJjLDM.html

I will definitely try this. How did you come up with 120 turns for the coil? Did you calculate it, or did you do so by experiment?

Could you ground it to an 8ft copper rod driven into the ground?

@@64samsky Yep! That will work great! Clean the area you are going to fasten the wire to with sandpaper or a file!

@@tz9392 You want it to go 10 to 12 inches across the tube! The number of rounds does not have to be exact. You can also us 16AWG (# 16 Automobile wire like you use for tail lights!)

That's an age-old setup that can certainly boost signals, and is easy and cheap enough. It is a useful weapon in the antenna armory... but I wouldn't say it is 'far better', at all. It's just a different tool. It might be louder, might ping your s-meter a bit more but louder is not automatically 'far better' than a good MW loop antenna... because it doesn't generally improve your signal-to-noise ratio. That much wire can be a case of diminishing returns. Most portable and midsized radios can overload very easily on too much antenna, distorting audio and causing imaging (stronger signals show up on multiple frequencies where they don't belong), and in severe cases signal overloading and even static build up on a lot of wire can zap input transistors/detectors. Of course, not everyone has the room for 250' of wire, so laying it out in various bends and angles to get it all to fit in whatever way you can make it fit the space you have only adds to its non-directionality, unpredictability and tendency to pick up just as much noise as signal. And then it can't be moved and aimed... and that's one of the main advantages of small loop antennas like the Crane -- directionality, aiming them not only to boost a desired signal but to also null out other unwanted signals on the same frequency, or a loud, splattery signal on a nearby channel, to kill interference or other noise. At MW frequencies long wires need to be much longer than 250 feet and in a *straight(ish) line* in order to become meaningfully directional (approaching a wavelength at least, which at MW is two or three times that)... and therefore being non-directional they will pick up as much noise as signal, so the induction-coupled long wire will not help you dig a weak signal out of the noise, not by itself (and even with added wires, not easily or cheaply). The Crane loop (like any small loop, ferrite or air core) on the other hand can be aimed easily to bring a fringe station right up out of the noise, and to separate/clearly hear different stations occupying the same frequency. You can't do that with a single long wire, and even if you lay out other wires they need to be long enough, and switched or phased to have the same ease of tuning as a small loop. I LOVE the induction coupled long wire antenna but I'm just saying, it's not better. It's another useful tool for the listener.

It may help. Directional Nulling is huge with this antenna. You would be adding the equivalent of a Superadio's antenna to your radio. I would do some research on the use of this type of antenna with a tube receiver. I have never tried it since I do not own a tube radio. Not sure if plate voltage "hum" (if I got that term correct) would be an issue with this setup.

Excellent Mitch, that is some serious DX.

Thanks! I have an adapter coming so I can hook it up to my RSP1A.... Should be interesting to see how that goes.

Awesome, I would like to know how that setup works out.

@@todderbert Will keep you posted.

Three foot.

Is this a 1/8" to 1/8" mono cord.

Yes, it was from one of my modular synths. Used as a patch cable for single channel audio.

The Tecsun R9700DX is decent: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-pR9UaloEljU.html , if you need cheaper, then the R9012: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-rZ5XSWgV-9M.html . The Twin Coil Antenna is designed for the AM Broadcast Band only. For Shortwave, just clip on a long wire to the antenna mast, or if the radio has an external SW antenna jack, you can connect the long wire directly to the radio, such as the 9700DX. I use the Kaito T-1 wire for Shortwave with excellent results, at Amazon: amzn.to/3pNHa23

@@todderbert many thanks 😊

Yes.

Excellent, sometimes car radios can be very sensitive on the MW band.

Yes.

Direct from the Company.

might want to research that, but I'm guessing a long wire of some type.

todderbert Thanks! I have been looking but I haven’t wrapped my head around it yet. Will keep looking! Thanks for the great videos.

If you hook up this receiving antenna to any transmitter you will destroy it! You need some sort of a longwire with an antenna tuner.

This runs on a 9V battery as well.

@@todderbert Not a selling point IMO

@@scottmerrow7617 It's an old design...

No, it is "tuned" for the AM broadcast band. You may want to look into those inexpensive MLA-30 MagLoop antennas, I have had decent luck with those on SW.

@@todderbert Thank you very much ! Love your show keep up the good work you do . Calling from the republic of ARMENIA.

Meant for Long distance installation. Though you lose the ability to Turn it for better reception.

I put mine on an antenna rotar

@@brendanb1541 Like outdoors on the roof kind of rotor? I'm talking about making a sort of rotating desk-organizer pen-cup kind of thing with the radio on the bottom, stationary, and the antenna element rotatable above maybe just behind it. A nice compact table setup for a portable radio up to, say, D808 size.

@@radellaf yes, up on the roof. I plan to mount my mla-30 up there too. Then I can turn it from indoors.

@@brendanb1541 Yeah, that’s a pretty different and more elaborate setup. Makes sense for the mla-30 (which also covers MW). I picked up the twin coil for its portability. Seems to outdo the Terk loop. My outdoor MW is a 50’ wire, plus a ground, that does a bang up job bringing in stations. Weakly N-S directional, but being on the East coast, that’s good enough. I’ve thought of picking up a mla30 but, really, if I get any more into outdoor antennas I’m going to go all out and put up a multiband ham radio vertical or V dipole. If the sunspots are active enough, a 10/15/20m would be doable. 40 is getting challenging, though there are trees available…

What a weird comment. I am sure he tunes all through the MW band all the time with this hobby, he just uses a handful of stations for these video demos. When he's not making videos I imagine he tunes all over the place looking for interesting signals. I mean, he's a bloody radio hobbyist, why would he have all these radios and antennas if he 'never looked for any other' stations? But you know, even if he didn't... why the hell do you care? What's wrong with having favorite stations? Weird comment.

He tunes all over the band in dozens of these videos.
