Text recognition is never 100% accurate. Many parts of the scanned page may not be reflected in the OCR text output, including: images, page layout, certain fonts or handwriting.
R-F LOADS and
WATTMETERS
For high power VHF and UHF applications
These Loads and Wattmeters are designed for convenient and accurate measuring of TV transmitter r-f power. The load properly terminates the r-f output of the transmitter and gives a measurement of the average r-f power. Easily installed — occupies little space. A choice of ratings is available for frequencies between 54 mc and 890 mc and for many power levels. Used by leading stations for many years.
3 KW, 54 to 216 MC
Designed for use to 5 KW of peak power. Termination type unit, supplied for operation in 54 to 21 6 mc frequency range. Water cooled. Designed for wall or rack mounting (not illustrated). Type MI-19024-A
50 KW, 54 to 216 MC
Supplied for operation in the 54 to 216 mc frequency range. Water cooled, it has an 84 KW peak power rating (not illustrated). Type MI-19191-L/H
25 KW, 54 to 216 MC
A water cooled termination type unit for operation in the 54 to 216 mc range. This unit has a 40 KW peak power capacity (shown above). Type MI-19193-L/H
1200 Watt, 54 to 216 MC
A natural air-convection-cooled portable unit. Type MI-19196-L/H. Has a peak rating of 2 KW.
25 KW, 470 to 890 MC
A column of tap water is used for power dissipation up to 40 KW on peaks in this termination type load. Type MI-19198-A2.
1 200 Watt, 470 to 890 MC
The type MI-19197 is designed with a peak power rating of 2 KW. (Companion unit to the MI-19196 unit shown at extreme left.)
7.5 KW, 54 to 216 MC
A water-cooled, termination type unit, it has a peak rating of 10 KW. Type MI-27396.
