Vertical antenna for DX

I'm thinking of getting one of these for the roof: http://www.eham.net/reviews/detail/315 That's my plan as the garage has a large surface area galvanized steel roof.

I trimmed Dave's post to reduce confusion - your alternative word, load, never appears. In fact, we never conjoin the term garage and load, nor roof and load, nor power lines and load. No, counterpoise has a well known and long established meaning that has been found in a lot of texts and none of the authors have ever felt the necessity to join that term with garage, roof, or power line either. Perhaps Newton kept his counterpoise in his garage - the historical record is rather vague on this matter. 73's Richard Clark, KB7QHC |

History informs us he would have called it a condenser, your word came into the language later from Le Compte a'Citor, Gauss's French Pen-Pal from junior high. 73's Richard Clark, KB7QHC |
