EDIT - The boom was upside down
Okay the antenna finally came! I am concerned that it is missing 3 holes though. Can someone verify if this is true? If so I will just drill them and make it work.
Also, I check some of the roof vents and they are pretty solid. They are metal and don't really wiggle. The boot is metal and is sealed with a kind of tape that looks more solid than a rubber boot. I think I will go that route and if it isn't working grab a tri-pod.
