They don't mention anywhere in their documentation what the coax was and it is a house brand with no labels, so I called them and inquired. GAP uses a RG-8X equivalent. I needed this information because they had a male UHF (PL-259) to go on the antenna, and I had a connector for a male 259 to go on the feed line coax. Also in my tool box I have a handful of male N connectors. So I went down to MRO Electronics in Calgary and got a female N connector to go on the coax. For those that are not as up to speed on coax a RG-8 and RG-8X are not similar at all.
As I assembled the antenna with the self tapping screws provided, I understand why several people have recommended changing the screws out for machine screws with lock nuts. As Winter was nearing in Calgary and I did not have many days without snow on the roof I needed this to get done and put that off to a future day.
I was unable to get the grounding installed for the antenna, so that will be a spring project before the lightning comes. Other than that I just need to poke a hole into the house, do some testing and get on the air.
Below is some pictures of the build.
