INSTALLATION

External Antenna Installation (Not applicable for DJ-491C):
When an external antenna is used, 50 chms coaxial cable is required for all antenna installations.
Please refer to the antenna manufacturer’s manual for the proper installation and mounting information. After installing your antenna, ensure that you have the proper matching and best possible SWR reading. High SWR or improper matching can cause severe damage to your unit and may void the warranty.
(Note: When your DJ-191 is used with an external antenna, you may experience some intermodulation problem from other communication services. This is caused due to the high sensitivity of the DJ-191’s receiver front-end circuit and its design for wideband operation. If it is the case, we recommend you to use an antenna that has a lower gain or the rubber duckie antenna which comes standard with the radio.)
