I'm installing a transceiver in an office on the ground floor of a warehouse. The antenna will be 45 feet above the office on the roof of the warehouse. The ceiling of the office is a drop ceiling, and above that is empty space until the roof of the warehouse.
My questions is about placement of the polyphasor lighting suppressor.
I know that usually it is desirable to put the lightning suppression as close to the antenna cable entry point as possible, and then to ground it, but I was wondering if it would be acceptable to install the lightning suppressor about 25 feet from the entry point into the building, right before it enters the office building where the radio is, and then ground it with grounding cable clamped to a grounded pipe.
My rationale is that it will be physically difficult to install it right on the inside under where the coaxial cable penetrated the roof, because it will be difficult to access. If it does take a lighting strike, and needs replacement, it will be very difficult to access if its near the topmost roof.
On the other hand, if it's right above the office, and it needs servicing, it's just a matter of using a standard ladder, and popping a ceiling tile. Keep in mind there are no offices above the first floor, only open space above the drop ceiling.
