One of the lessons learned from our group’s activities at the Oso mudslide was that sometimes it would be very, very, VERY handy to be able to get an antenna up in the air – say an additional 20 to 30 feet – to get over nearby obstacles and otherwise get a better and clearer signal – both in and out.
As a result, I now have a portable (loosely defined) pole/mast that in theory could get up to 40 feet high.
