Drilled through the flue

I drilled a 1 inch hole through what appears to be 1 to 2 inches of ceramic flue. This is an old incinerator flue that hasn’t been used for 40 or so years and we use it as a cable shaft.

I drilled a 1 inch hole to accommodate the PL259 already on the cable. I am using LMR 400. Next step is to drop a rope down the chimney, feed the Coax through the hole, tie them together in the basement and pull the coax up to the antenna.

lets see how it goes.
