Installation / Setup
The installation of the Kenwood SSB Radiotelephone TKM-707 involves several steps to ensure proper operation and safety. When selecting a location for the mounting bracket on a vessel, consider ease of operation and safety. The bracket should be installed using the supplied flat washers and self-tapping screws or spring washers and bolts. The angle of the bracket can be adjusted to three possible viewing angles.
For connection, the radiotelephone requires a maximum of 30 A at 13.6VDC ± 15% when transmitting at full power. It is important not to exceed the length of the supplied power cable. The type of antenna used significantly affects performance. A properly adjusted antenna with an input impedance of 50 ohms is recommended. Use 50 ohm coaxial cable, such as RG-8U or 8D-2V, for the connection. A wire antenna should be between 2 to 24 MHz and have a total length of 12 to 23 meters, with a longer antenna preferable for low frequencies. The antenna should be erected as high as possible.
