[Lowfer] Should we make comments on 1750M?

John,

I like all of the features of your proposal with the exception of the 
no-size limit on the antenna. I would propose a reasonable limit like a 
100ft tall x 100ft radius cylinder (or maybe specifying the volume of the 
limiting cylinder?) to keep the crazies (like me) from going 'hog wild'.
