When buying a used antenna or considering when it may be at the "end of it's life" one might want to consider where the antenna was located. I am finding coastal Florida to be much worse at weatherin

Hopefully Force 12 will use heavier gauge aluminum on their elements and booms one day. As-is the standard Force 12 antenna is built for light duty service. A fellow radio amateur here in Maine bough

Force 12 needs to do more homework. It should not be necessary for the consumer to have to do all this work (take the antenna down and modify it several times) to make a mass produced factory built F
