I currently have my discone antenna on the top of my porch on a 10 foot mast with a Radio Shack 3 foot 3 leg tripod mount. I want to raise the antenna above the peak of the roof. I can either put the tripod mount on the peak of the roof (not very easy on this roof, no access to it), or, I can add a 2nd 10 foot mast to the current confguration. My question is do I need guy wires in the case of high winds? Or, should it be fine as is?
