You can calculate the power dissipated within their connector at 1750

Great engineering is applying applicable and useful aspects of science to solve a particular problem, not chasing angels dancing on the head of a pin. :) Hardware, construction, and design techniques needed for 1.7 GHz are very different from those needed at HF, which is Pete's application.
