Hi, I have a 22 foot classic. I bought a King Jack antenna. I have an air-conditioner mounted on the roof. There is mark on the ceiling near the cabinet left of the refrigerator that says "antenna mount". The instructions state that the outside antenna needs to be 20" minimum from anything taller than 8" inches. If I mount the antenna here it is only 10" from the air-conditioner on the outside which is 10 - 12 inches tall. I found a place above the refrigerator to the right of the battery operated light. Can I mount it here or will I damage something? Maria in Oak Harbor, WA
