FWIW, my experience has been that 73 material is "better" than 43 material for HF transformers and baluns. Another turn or two (above what's specified for 43 material) could be necessary though. The 43 material might be "better" for 160-meters, AM-BCB, etc. YMMV, of course.

Should Dipoles Made With Insulated Wire Be Made Shorter?

NettetFor antennas I do prefer the coated or insulated wire. The reason for this is that coated wire can be easier to work with as if it touches something conductive such as metal it is OK. Bare wire must be kept away from anything conductive to work properly. If bare wire comes into contact with anything conductive that material becomes part of the ...
