Any body know the height from the top of the new Jack Type ( pedestal vs retracting batwing type ) antenna from grade ? Bounder states that the height is 12 ft 10 inches but I believe that may be based on the roof AC Unit ( not necessarily the Antenna ). I want to make sure I clear the bridges/overpasses labeled as 13 ft since with the AC unit there is only 2 inches of clearance.
