PART Ill — INSTALLATION AND OPERATION 
1. INSTALLATION 
1.1 SHORE EQUIPMENT > 
The ‘‘Shore Equipment’’ has been designed for use either on the towing carriage or for a 
fixed installation in one of the testing areas of the Model Basin. All shore equipment may be 
located in a group or, if desired, the battery charger may be located at a convenient point near 
the water, and all other equipment at a position allowing an unobstructed view of the maneuver- 
ing area. 
1.1.1 Console and Antennas 
The console should be positioned so that the operator will be able to view the model 
maneuvers over the top of the console. This will permit the operator to watch the model and 
the console indicators much as the dash panel instruments of an automobile are observed 
while driving. 
The transmitting and receiving antennas should be vertically mounted with a spacing of 
10 feet or more between antennas and positioned so that metal objects or personnel will not 
intercept the path between the shore-based antennas and those on the model. The cables 
between the console and the antennas should be of Type RG-58/U in order to maintain proper 
impedance matching. The length of these cables is not critical; however, it is desirable that 
their length not exceed 25 feet because of the high cable losses at the operating frequency. 
NOTE: Transmitter power should never be turned on unless the transmitting antenna is 
connected. 
Two power input connectors are mounted in the base of the main pedestal of the console. 
The 60-cycle power for all electronic circuitry should be regulated to 145 volts + 5 volts and 
connected to the left input connector; see Figure 10. Maximum regulated power required is 
600 watts. The other power input connector should be connected to an unregulated 115-volt 
60-cycle power line that is always turned ON. This supplies power to the console cooling, 
heating, and illumination circuitry. The heaters are turned ON whenever the OPERATE 
STANDBY switch is in the standby position. This is to prevent the accumulation of moisture 
within the console when used in areas of high relative humidity.” Unregulated power is 
available at the fused outlet on the front of the console and may be used for the operation of 
test equipment or a soldering iron. The maximum unregulated power requirement for the 
console equipment is 100 watts.
