Jim thank you for the three excellent and thorough posts.
My plan is to put the antenna together, mount it on a mast on the back
porch, to see how it works.
Later to add a roater that I can operate from the computer.
First, I will be using a calibrated armstrong roater.
The mast is right next to the door out to the porch, so a handle on the mast
will work fine.
Maybe next winter I may re-consider this low cost option.
Oh well I need the excercize of running up three flights of stairs.
It will do my blood sugar good.
