Thanks for your reply 4StanleyCups!
The bad news is my roof chimney is really short, and it's sitting on lower portion of the roof. I guess MN doesn't have the same code for chimney.
My house is right next to a big lake, but backed into heavy woods. We could have high winds at times in winter, but I just moved into my new home about 2 weeks ago, I have no idea how windy it could get....
My coworker told me that I can put in a retractable post in my backyard, and just extend the thing all the way out of tree line WITH a dish on it. Good idea?
I guess my new neighbor will kill me if a big metal post will fall on his roof...
Man, I knew I should just get that house sitting right on the lake shore in my neighborhood, It's just 2.5 million more..... who cares.....
Any other thought please?
