What is the easiest and safest way to raise a 30' mast and antenna by myself? I thought about screwing two 1x4"x 8' together and then two more to the outside of those with a block near the top to cradle the mast as I walk it up. Once vertical it will rest between the house and chimney until I can manuver it into the wall mounts. I've walked up 20' many times in the past, but I don't think I can do 30' with ten feet of antenna on top. Any suggestions to do this myself?
