Hello all, I am planning to erect an 80 meter full wave loop antenna in the back yard. The articals I have read so far all seem to feed the antenna at a corner with either 450 ohm open wire line or feed direct with 50 ohm coax. Due to the layout of my yard it would be preferable that I feed the antenna at the mid point of one side of the antenna with 450 ohm open wire line to a tuner (4:1 balun included in the line and coax to the tuner). Is there any disadvantage in feeding the loop mid way along one leg rather than at a corner?

any assistance greatly appreciated
