hi

I was wondering a few things i read about in my sgc tuner manual about
dipoles


a) they say or sorta recomend that if your making a simple horiz ctr fed
dipole, it's 'best' to have one leg longer

why is that 'a good idea' what happens that makes this sorta advisable


b) they recomend the longer leg to be the rf 'ground'' side , really
confused as to why, my gut would tell me to make the hot side the
longest leg so i am confused



can anyone help me understand the above, i kinda understand how the wave
looks on a regular horizontal ctr fed dipole is


any help appreciated
