The calculated range with the "T" Antenna and this transmitter for most locations in the United
States and with one of the lower priced ADF's is from 80 to 100 miles except over low conductiv-
ity ground.
States and with one of the lower priced ADF's is from 80 to 100 miles except over low conductiv-
ity ground.
These range figures are for the standard "T" Antenna with a height of 55 to 60 feet. A long range
"T" Antenna with a height of 80 to 85 feet has a range of 100 to 120 miles. If even more range is
desired, SAC can supply "T" Antennas with heights up to 200 feet.

desired, SAC can supply "T" Antennas with heights up to 200 feet.
The standard "T" is electrically very similar to a 1000 pF capacitor in series with a small resistor.
See the fiqure at the end of this section for a plot of the capacitive reactance.
