I would concur - something like a small foot print K9AY with the "steerable" null I use here (there) in Alaska to reduce my MW blowtorches. In fact life on some frequencies without a directive or moreover nullable off the back array is a must in my case on some bands....just hope the very tight null isnt in your favorite direction!

Not sure of your footprint and ability to shove something up....
