DESCRIPTION Two existing Teltrac antennas (completed in 1963) located at the
east and west ends of Apartment Building 699 are available for primary tracking.
The rotating parts of the antennas are balanced, and are mounted on 24-ft. high
steel platforms. The tracking rate on any axis is 20 degrees per second, The
Supporting structure of the Teltrac is designed so that deflection or rotation from
a 30 knot wind will cause an error of less than 0.1 degree in tracking. Slaved tc
the Teltrac antennas are the command antennas and the AME antennas.
