Those of you who a thinking about a 43 ft vertical or how to feed it might read the links I have provided you here. I have built a 43 ft vertical from a 50 ft telescoping Rohn push-up pole. I am using a mesh ground system under it thanks to Home Depot's 4ft x 7 ft mesh sheets linked together, radial wires, grounding rods, and a homebrew balun. I am using a K2 with ATU and 100 watts through a short run of LMR400 coax to the base of the antenna where the balun is located. The 43 ft vertical also supports my windom. The windom is insulated from the vertical.
Below are several links on the 43 ft antenna including the AD5X info on how to build your own balun. I based my balun on his and it works fine. If you do not wish the build your own balun, a great one can be purchased from Balun Desins LLC. They offer two models for low and high power. The links are all there. http://vk1od.net/antenna/multibandunloadedvertical/index.htm http://www.balundesigns.com/servlet/the-Ununs-for-Verticals-%26-Longwires/Categories http://www.ad5x.com/images/Articles/Match160.pdf http://www.ad5x.com/images/Presentations/Vertical43.pdf 73 Dave Little, AF5U ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html
