For the least amount of interaction with the elements, bring your coax out at a 45° angle from the boom to 
mast plate. Allow about 3’ for the drip loop, then attach the coax to the stacking frame. Be sure when dressing 
the coax along the boom, you do not let the coax touch an element or the keeper.
