If you are using the Polydoroff configuration, then YES. Now that you areincreasing the length of the rod, you should be able to use a 4coil Polydoroff configuration. If you are wanting to make it a

Remember the ferrite antennas you made for my PL-360 which plugged in the top? What value of uH did the PL-360 like best tuning the AM BCB? - FARMERIK

Would you think multiple coils in series are significantly better than one winding, or just a little better? -FARMERIK

You do not need to glue, or space the toroids, I have tried it both ways. Just get a 1" dia dowel rod and cut it just slightly shorter than the total length of the 18 stacked toroids. Then use wood,

I couldn't help myself and ordered 8 more toroids. My plan is to have 3 coils wound which will have a total uH in series for AM. I think those windings will cover 2 toroids, but 3 would be fine too.

I did not experiment with a pick up coil on the one using that 2" dia toroids. However, if you will look back at some on my past articles I have info on using a coupling transformer using binocular

Another question about your [Eversharp's] new anteena wound on Toroids, have you experimented with a pick up coil, and if so what worked best to connect directly to a radio. I guess the usual way is

My homemade Palstar clone and Quantum clone loopstick tunes up to 2MHz. If my location was only quiet enough to hear anything <sigh>! Maybe some day...!

I'm using a Wellbrook ALA1530 right now, listening to 5070 kHz and it does great even for the AM BCB. I can even listen to the FM BCB pretty well although they say the range is 50 kHz - 30 MHz. If I

A 2 coil Polydorff might be a good option. It will take a little more than just one coil. Everett N4CY

Sounds like it should make a very interesting antenna for me. I should have enough 660/46 Litz left over from the special low uH antenna for the Fisher AM 80 which I am having made on a 12 inch X 1/2

The spacing was the same that I used in the article that wrote and at the time worked out to be the best option. The tuning was sharp, indicating high Q and the loop rotation was quite sharp also.

I'm in. I just ordered 5 pairs of those toroids. I hope my repair guy will wind them for me. How did you decide the thickness of the spacer between the winding and the toroids? With Litz, are you

Sorry, but since I don't have a solid ferrite rod that size to compare it to, nor would I want to pay the price such a rod, I can't answer you question. I can tell you that it is much better than the

I am impressed with a ferrite loop which compares so well to such a large air core loop. I have followed a number of articles available on line, including yours in the files section of this group
