Those would have worked with the TH7, but at the time of mounting the TH7 I
had no stock of FT240-61.
The balun on my TH7 was a coax choke wound on a large 4C65 (~61 mix) Toroid:

Subject: Re: [TowerTalk] Which Balun with the TH7DXX
The 2.4 inch 61 core is part number 5961003821.
I use them for stack match transformers from time time or for small baluns
wound with RG142.
13 turns of RG142 on a single core give me 30uH, same as my solenoid chokes.

You use these for Hy-Gain TH7 antennas?
