I have owned a TS-480Hx, and used it long enough to learn more about it than you apparently have, John.
Apparently not because you do not because you did not even know how to mount it.
In any case, it would serve you better not to be so abrasive and indigent.
When you stop giving BS answers... (remember first you said any position is fine then you changed because YOU DID NOT know without google) I have read your posts and auto makers have it all wrong and you are right huh. Just like 3/4 wave vertical should work great on 440 when they suck worse than a Jpole. And suddenly a expert on electric cars too but do not own them. My Volt we have owned for two years NEVER got your memo that it was supposed to be noisy.
