More than enough for my purpose. I cracked open a couple and foundd that tthe type that go frm screw connectors to male F connector have a larger transformer than the barrel type. This was at least true for the couple that I sacrificed to the radio gods. K3MT"s data was on the barrrel or tubular type. Jimmie Hi Jimmie, So, going further with this resource you found, was there any report of how "well" it worked? Merely surviving the application of 5 to 10 Watts isn't exactly proof of suitability for performance. Even a SWR report could mask the fact that a BalUn inappropriately applied is operating as a padding resistor. Going further yet, was it reported what style of BalUn it was? Guanella? Ruthroff? Not all BalUns perform equally, and for reception (the class of BalUn you are mining for transmission application) it is arguable that it matters. Lastly to your first statement Googling TV BalUn was useless but searching fot 2M Balun proved more useful. The distinction was useful, but were you Googling the Web, or this group? 73's Richard Clark, KB7QHC |
