Motorola BRKT-70661-01R mounting kit

Standard – Two plates with an articulating joint
It has a 2.75” x 5.88” mounting plate and one swivel joint and one swivel plate. This is good when you have plenty of room where the antenna will be installed. With this bracket you can tilt the antenna up/down and side to side. Due to the closeness of its installation to a surface you will be limited in the amount of room you can turn or tilt the antenna.
