Agreed, but be aware that most contest rules specify power at the 'TX Output' not at the antenna. 

RSGB are clear on this but I had to confirm this with the organisers of CQWW last November as their description is (was?) ambiguous. Only an issue as I wanted to site an antenna a *long* distance from the shack.....
