26-29MHz High-Power Mobile Antenna
CR-10H
OPERATING INSTRUCTIONS
DESCRIPTION
1. The CR-10H is a wide band coverage mobile whip antenna.
2. The antenna is designed largely and high power to
achieve 2m total length.
3. 17-7PH High-tension stainless steel is employed in the
upper element and specialized square block is used in
loading coil to have high power rating.
INSTALLATION
Since the antenna uses a car body for its ground, vswr of the
antenna can not be lowered
if antenna bracket is not contacted to the body perfectly. Be
sure to see if the bracket and body are well contacted before
installing the antenna.
Please note that vswr of the antenna can not be lowered if
the antenna is installed very close to another antenna or the
antenna is installed directly on rear bumper of the car.
CR-10H is very heavy and long antenna so please install it at
the well-strength place.
ADJUSTMENT
Please refer to the below cutting chart and cut the element.
(Note) The frequency of chart might be different depending
on installation condition.
When adjusting, please cut the element longer than the chart
(3-5cm) and confirm the frequency. Conclusively cut the
element.
The adjustment has to be practiced by parking the car at
wide flat place where is no obstacles around the car. Please
note that set screws have to be refasten after the adjustment.
