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 possible. Loop wire through the choke at least 3 times. (Picture 11) It is used to decouple the control cable from the antenna.

Page 7: Operation
IMPORTANT: Don’t make any adjustments to the matching coil until you read and understand the next paragraph. Now you need to go to the middle of 40 meters and check your SWR. Record that and then go to 80 meters and do the same. Your standing wave should be below 1.5 on both bands. If it is below 1.5 on both bands no adjusting is needed on the matching coil. - Page 8 Model 100A-HP -- 21.2 MHz with 5 ft. whip @ whip -- 29.0 MHz 1/2" of coil showing Model 100A-HP --14.2 MHz with 5 ft. whip @ 1 Model 100A-HP -- 7.1 MHz with 5 ft. whip @ 5" of 1/2" of coil showing coil showing...
