I have a couple of antennas that are available for sale.
6 meters: I have a j- pole need to be tuned, made out of copper. Free
6 btv: 6 band trap vertical. This antenna covers 80, 40, 30, 20, 15, 10 meters it can easily and for almost no cost be made to cover 17 and 11 meters. This is a second vertical and i can attest, you meed a good radial system for this antenna to function properly, I will gladly show you what I did to
Make mine perform well.
