Review on Trunknets Inc ANTENNA MAST F 150 by Mark Bearden

Listen to the reviews -- Item didn't last 2 weeks! I installed the antenna and two weeks later it fell off the car. This product is poorly constructed, the antenna is attached to a screw post which then screws into the vehicle's antenna mount. After two weeks of riding the antenna was gone but the screw strut stayed in place. The antenna itself was detached from the top of the screw post. In my opinion, the antenna is not properly attached to the screw post itself, so firmly attaching the screw post to the vehicle did not help. Now I have to buy another antenna (but definitely not this one).
