I have an S9 43' vertical. You will need the unun to match 60 meters and up. The 80M coil works well too. I ended up building the matchbox that Phil AD5X designed. You can see his article here:
http://www.ad5x.com/images/Articles/Match160.pdf Phil also has a nice presentation on the 43' antenna here: http://www.ad5x.com/images/Presentations/Vertical43.pdf It's a great antenna if matched properly. It must be matched at the base with a remote tuner, an unun, or coil to work properly. The unun (on 60M and up) keeps the SWR down to manageable levels that you can match with a tuner in the shack with acceptable coax losses. The SWR gets out of hand below 60M and must be matched at the base. 73 Bill nz0t -- View this message in context: http://elecraft.365791.n2.nabble.com/K3-S9-43-Vertical-tp6193993p6196827.html Sent from the Elecraft mailing list archive at Nabble.com. ______________________________________________________________ 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
