A voltage balun normally can be used in reverse. Frequency response changes and moves lower. A current balun using transmission lines has a little line balance problem and much more limited high frequency response when reversed. How it works depends on how long the transmission lines inside are, in particular one of the lines (on the upper non-inverting TLT) and what you accept for SWR. 73 Tom ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:[email protected] This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html
