Put a 50 ohm resistor or dummy load on one side and connect the other to an antenna analyzer or radio with SWR bridge. If the SWR is close to 1:1 then it is a 1:1 balun. If it is more like 4:1, then it is a 4:1 balun! On 9/14/2012 6:14 PM, George Averill wrote: > I purchased an old used balun at a hamfest. It came with an instruction sheet for both the 1:1 and the 4:1 baluns. All the markings are gone on the balun. How can I tell which one it is? The balun is sealed. > > George -- Vic, K2VCO Fresno CA http://www.qsl.net/k2vco/ ______________________________________________________________ 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 ----- No virus found in this message.
