Pneumatic telescoping 7 section portable tower 30 feet / 9 meters tall. AR40 rotator. Kinda heavy since it has tri telescoping tubes. Each section is about 4' 8" / 1.4m. Total weight 120lbs/55kgs More info at http://ka6puw.tripod.com/index.html. Good points are that the tri masts don't spin or flex and heavy antenna will not kink the tubes when you lower it in windy conditions.
