Thanks Richard for the new frontiers!! :-) I am learning a lot.

Mine is a center fed dipole with a 1:1 balun which feeds both 40m and
20m dipoles. The ends are at unequal heights because I couldn't find a
convenient way to tie the ends in the terrace.

My next experiment is to measure SWR at dofferent frequencies. To make
things simple, is there some kind of input signal suggested? Shouting
can easily come down afew decibels, after going up and down the stairs
adjusting the dipole angle and lengths. :-) I don't have a CW key yet.
:-( So what's the other option?
