Jerry,? There is an even simpler way to determine which of our theories is correct.? You, Allison and others believe the EFHW is carefully engineered to generate multiple resonances that fall into

Re: End Fed antennas w/ uBITX #ubitx
Warren, did you look at the curves published on the my antennas website? They clearly seem to know when their transformers have losses and when they don¡¯t. Here is one of their curves that shows

Re: End Fed antennas w/ uBITX #ubitx
Jerry, I understand the argument you and Allison are making. You believe the MyAntennas combination of a specific length wire and a carefully engineered transformer together produce a series of
