Installing
The SCU-30 is designed to be mounted on a base, installed on an extension pole or ush mounted.
Choose a location for the antenna unit that has not located within 3 feet of radar or other transmitting 
antenna. Ensure there are no  major  obstructions or xtures in the immediate proximity to the anten-
na unit. If you are unsure of the location, temporarily mount the antenna to verify correct operation. If 
mounted close to a radar, turn on the radar and check the to verify correct operation.
Compass Safe Distance
This antenna unit at least 0.2m (0.66 feet) from magnet-
ic compass.
Base Mounting the antenna
The thread used on the base of antenna (1 inch, 14 TPI) 
is an industry standard used on a wide range of commer-
cially available  mounting  brackets or  extension  poles.  
Due to the manufacturing process of the mounting brack-
ets, the antenna may not tighten all the way down onto all 
the threads. This is of no concern however as the anten-
na must be tightened until the antenna stops rotating.
1. When passing the antenna cable through a mounting 
bracket or extension pole, make sure to pass the ca-
ble through the antenna base.
NOTES:
・When routing the antenna cable along the outside of 
the extension pole, pass the cable through the groove 
as shown by the dotted lines in the gure on the right. 
(Please cut the blank panel with a long-nose pliers.)
・The antenna cable can be cut and spliced to ease installation. Care must be taken when reconnecting 
the antenna cable to protect from water and corrosion.
2. Mount the antenna base to the antenna using the supplied three screws.
3. Screw the antenna base to the mounting bracket or extension pole.
4. Install the mounting bracket or extension pole. 
Flush Mounting the antenna
NOTE: Before drilling the mounting holes, it is 
recommended to verify correct  opera-
tion in the desired location.
1.  To ease installation use the supplied flush 
mount template. 
2.  Apply the ush mounting template sticker.
3.  Drill the 0.78” (20  mm)  and  0.13”  (3.2  mm) 
holes, and remove the template.
4.  Insert the cable into the 0.78” (20 mm) hole 
and route to the transceiver.
5.  Apply a small amount or RTV to the under-
side of the antenna.
6.  Place  the antenna and screw into place us-
ing the supplied screws.
Template
Use this template to mark the 
location where the hole for 
the ush mount is to be cut.
