Yep agree. but unless you get the pressure spot on it crushes the cable. staple guns only have 2 settings, and there is no way of judging the hardness of the particular spot you are driving one into, so even if they had multiple settings, still no good for a coax. when i say crushes, its only a minor change of the shape of the cable that is needed to affect it, so staple guns are a no-no in the coaxial world
