Hello All,
I'm putting a loop up on a flat roof. Height will be around 50 ft and the
roof dimensions are 37' x 160'. I'll be using my Icom AH-4 coupler to tune
and will be feeding it in the middle of the north 35' section (160' sections
run east-west). I hope to run all HF bands.

Which direction will be the best as far as gain with the above setup? North?
Would it be better to shorten the loop at all?

73!
