It's always been in my head to try an actual C.Crane Twin Coil Ferrite Signal Booster. I've used tuned Q-stick devices before with a lot of success. They have sharp nulls and lots of inductive gain. The Crane unit promised more of the same with its 8-inch twin coil ferrite rod.

Checking the Crane website the other day, I was shocked to find that they have discontinued it. Now, if I want to give it a try, I'll have to find one elsewhere - maybe eBay. I see there are a few of them out there yet. I'd advise you to pick up one of these fabulous goodies before they are gone forever.

The patent on the Twin Coil Ferrite expired, so anyone could take this on perhaps?
Ian, you bring up a great point. Maybe someone will pick this up and run with it. Since the patent is expired, I don't see why not.

I have one of those. Reach out to me at jock@swling.net

C. Crane and Co., will have a table at our annual, Radio Day by the
Bay-2024 on Saturday, July 20th. We are the California Historical Radio Society in Alameda, California and as the CHRS' Volunteer Coordinator I'll endeavor to ask their representatives on site about this situation and perhaps, any others which could be of interest to us DX-ers!
Best to all,

Hello Kim. I'll be eager to hear what Crane's response is. This was a great product. Good luck out there and have fun.

Thanks, Bill!
Greetings once again: Radio Day-2024 was an unqualified success this past July 20th. You can check out the activity, sights and sounds at our CHRS website at: www.californiahistoricalradio.com
Anyway, I did have an opportunity to chat with Scott from C. Crane Radio who was one of our sponsors at Radio Day. I asked about the discontinued Twin-Coil Ferrite Antenna. He confirmed its demise due to the cost of altering the design, etc. in order to secure a new patent (yes, the original patent did expire) being cost prohibitive in light of overall poor sales. In essence, it would cost too much money to continue production with a low probability of new sales.
Will they come up with something new to replace it? Scott indicated at this point in time anything is possible but, nothing is currently on the drawing board. Sorry...wish I could give all of you better news.
Thank you for the update, and for getting back to us. Interesting stuff. Would you mind if I quote what you found out, either as an appendix to this article, or a separate post?
