Transmission Line (TL)

Purpose: To generate a transmission line between any two points on the
         structure.  Characteristic impedance, length, and shunt admittance
         are the defining parameters.

          Cols	Parameter
         ----------------------
          1- 2        TL
          3- 5        I1
          6-10        I2
         11-15        I3
         16-20        I4
         21-30        F1 
         31-40        F2
         41-50        F3
         51-60        F4
         61-70        F5
         71-80        F6

Parameters:
   Integers I1-I4 - (the integer specifications are identical to those 
            on the network (NT) card.)

   Floating Point
         (F1) - The characteristic impedance of the transmission line in
                ohms.  A negative sign in front of the characteristic
                impedance will act as a flag for generating the transmission
                line with a 180 degree phase reversal (crossed line) 
                if this is desired.
         (F2) - The length of transmission line in meters.  If this field
                is left blank, the program will use the straight line dis-
                tance between the specified connection points.

                The remaining four floating-point fields are used to
                specify the real and imaginary parts of the shunt admittances
                at end one and two, respectively.

         (F3) - Real part of the shunt admittance in mhos at end one.
         (F4) - Imaginary part of the shunt admittance in mhos at end one.
         (F5) - Real part of the shunt admittance in mhos at end two
         (F6) - Imaginary part of the shunt admittance in mhos at end two.
