@relistan Very tidy construction. I too ordered some RG316 but it's very stiff and I'm hesitant to bend it tightly around the (I guessing) FT240-43 core. I also have some RG174 which is much easier to bend.

Is there any particular reason for using RG316 instead of RG174 as the losses in the short length used will be very small, and the breakdown voltage (at least with 100W) shouldn't be a problem?

@gmoretti thank you!

I don鈥檛 think you鈥檒l see much difference using RG-174 coax. My previous build was fewer wraps of RG-58. That construction is very common. Some people use unshielded wire for this. I had RG-316 on hand and, at least with the stuff I have, there was no problem wrapping the toroid. The casing is stiff but not so stiff as to be a problem. There was no damage to the coax. You are correct, the toroid is an FT-240-43. Good luck! 馃崁
