I had some questions regarding a MA8040 Vertical I am installing and emailed Cushcraft.
Within an couple of hours [and on Good Friday] I had received a reply and was informed the Engineering Dept. would be consulted.
Again, within a couple of hours I had received their suggestions regarding my installation.
I was very impressed with and thankful for the timely response from them. It allowed me to proceed with my antenna project this weekend.
