The heavy wall aluminum mounting sleeve is epoxy coated for superior weather protection. Lightweight: These antennas are lightweight at less than 8 lbs. but are designed to easily withstand winds of over 100 MPH. Simple installation: Using the optional BSMNT2 mounting kit, installation takes only minutes.
