Page 3: Installation
Installation Before installation of this antenna there are a few things you have to consider. To get peak performance you need to try to mount the antenna in a location where the decoupler (this is where the coil comes out of the antenna) is at least as high as the highest part of the vehicle. - Page 4 The MT-1 antenna bracket is designed to make your antenna mounting convenient and incredibly strong. Made to clamp to standard 1” pipe (1.312 OD) or bolted to a flat surface. (Picture 6) Picture 6 There are a few steps to make sure you install the MT-1 antenna bracket the way it is intended.
- Page 5 Included with the antenna is a special mix #31 ferrite core that needs to be mounted on the control wire as close to the antenna as possible. Loop the wire through the choke at least 3 times. (Picture 11) It is used to decouple the control cable from the antenna.
