The KING antenna was installed easily. the matter for us was that the coaxial cable's center conductor corroded or a lightning strike melted it (there could be a difference of opinion there). However, we had to run the line from the barrel connector inside the ceiling to the bottom of the antenna than to the
new antenna. It takes an extended time, but with the amazing help I had, it only took two hours. The reception is amazing. The new head feels a touch heavier than the old "wing" with its HD attachment which makes starting a bit harder, but no problem.
