So I have several questions: You could try the same thing but on the opposite side of the vertical and make a quarter wave addition for 12m. I could do this in about 15 minutes, got lots of wire and insulators in the junk box and could suspend them from the guy ropes. What is the the pro's and con's of each of them. Also easy to install some nylon guy lines if you feel it is necessary. New to Ham Radio?
I suspect the spider is a marketing gimmick.
17m and 12m added to Hustler 6BTV
But would it be good investment to protect the antenna? I am currently using a 6btv vertical and would like to add the other 2 bands. The old AEA Analyzer is worth its weight in gold. Simply put, why not? It was already pitch dark outside by the time I finished with the adjustments.
