Symmetrical "T" Antenna - SAC SS-800AVS Manual

The Guyed Mast Antenna is electrically very similar to a 300 pF
capacitor in series with a small resistor. See the figure at the
end of this section for a plot of the capacitive reactance.
4.4 Symmetrical "T" Antenna
The Symmetrical "T" Antenna is recommended if sufficient land is
available. This antenna requires a plot of ground approximately 150
feet by 350 feet.
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 i00 miles except over low conductivity 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 i00 to 120 miles. If even more range is
desired, SAC can supply "T" Antennas with heights up to 200 feet.
The standard "T" is electrically very similar to a i000 pF capacitor
in series with a small resistor. See the fiqure at the end of this
section for a plot of the capacitive reactance.
