2.5.7 Antenna Considerations
A number of factors should be considered before erecting an antenna. Radio signals are absorbed and reflected by
nearby obstructions such as hills, trees, buildings, and power lines. Avoid these if possible, especially when they
are in a direct line with the RF signal path. Signal strength is usually greatest from the top of a hill, over level
terrain, or over water. Mountainous or hilly terrain may present unpredictable transmission or reception problems.
Some antennas are more directional than others, and must be correctly oriented for maximum signal gain. A good
earth ground connection and radial grounding system improves antenna performance and protects the equipment
and personnel from lightning and electrical shock.
2.6 INSTALLATION CHECKOUT
Installation checkout has three phases. Paragraph 2.6.1 is a pre-power up check to make sure the system is
installed correctly, and that all support items are available. Paragraph 6.2.2 covers the radio system’s power up
and preliminary tests.
2.6.1 Inspection and Pre-Power Up Procedures
When the RF-5800H 125-Watt Communication System is installed and all connector cables are attached, verify
that the following items are completed:
•
All connectors are attached and associated hardware is secure.
•
System units are connected to ground, preferably at a single point.
•
Ground wires are connected between the radio system units and a known good ground.
•
Ensure all hardware is tightened.
•
Area cooling is adequate for removing heat that may develop during equipment operation.
•
Power source is of adequate capability and adequately protected for the radio system’s load, and that
installation of the power cable is correct.
•
Antenna is in place, correctly connected, and protected against accidental contact.
•
Companion equipment, such as the RF-382A, or remote control, are in operational readiness condition.
2.6.2 Initial Settings and Power Up
Perform the following procedure to power up the RF-5800H-MP and RF-5832H-PA and execute BIT:
a. If the system is vehicular, skip this step and proceed directly to step b. Turn the power switches of the
RF-5051PS to the ON position.
b. On the RF-5800H-MP, set the function switch to the PT position.
c. On the RF-5800H-MP, press the OPT pushbutton.
d. If necessary, press the left/right arrow pushbuttons to select the TEST field.
NOTE
While in TEST mode, the RF-5800H-MP cannot receive or
transmit.
