My home-made ferrite antennas
dfroula:
Well, I used 26AWG enameled wire with a total winding length of 240mm. .42675mm thick, including insulation.
That would be 563 turns, 7.5mm diameter.
563 * 7.5 * Pi = 13528.65mm of wire or 522 inches of wire (43.5 feet).

thks!
dfroula:
I tried a 1" drop test on the glued cores. Every joint fractured. The cyanoacrylate is NOT a good choice for gluing these rods. The assembly would be far too fragile and subject to undetected breaks.
I'll repeat the procedure this weekend using 15 minute 2-part epoxy.
Regards,
Don
Beaudog:
The cores look to be hollow. I would run a wooden dowel thru them prior to gluing (they might not even need gluing)them together this should make them considerably stronger and less prone to break. I don't think it would have any if much effect on their Q.
dfroula:
No, the cores are solid.
