Hate to co-opt a thread, "grnd noise base radio" here but if you'd elaborate on Teflon wire? By silver coated might I presume "tinned" strands is meant?
Or, are you speaking of coax, perhaps RG-400, when speaking of Teflon?
Yes, a 1:1 choke Balun. Too young to know benefits of any other. Number of pass-through windings is of greatest importance. Wanting to narrow down or make Balun focused to 25-30MHz bandwidth, if advisable or beneficial?
I'd gave thought to magnet winding wire; but, deterrent was wire at hand, 18 & 22 AWG. I'm thinking, wrongly or not, a 14 or 12 AWG would stand up to 1500W longer. And am inclined toward silicone jacket for flexibility.

Seems 11 turns of RG coax prevalent in their 1.8-50MHz Baluns.
LFA Yagi Uda sure appears to have great advantage over NBS Yagi, at least on paper.

Reason: mag wire V 12 AWG; silicone; coax/teflon;1.8-50; LFA v NBS
