Dallas, you can do it with program TL: http://qrz.com/files/antennas/tl.zip only 30Kb and free This program can calculate what do you need and more. One screenshot from it: ------------------ TL (Transmission Line), Copyright 1993-1994, ARRL -- by N6BV Length of line: 30.00 ft Frequency: 145.000 MHz RG-58A Cable Matched-line attenuation = 1.97 dB Real part of load impedance at antenna (ohms): 1 Reactive part of load impedance (- cap., + induct., ohms): -50 SWR at load: 100.01 SWR at line input: 4.31 Additional line loss due to SWR: 11.93 dB Total line loss: 13.90 dB Real part of impedance at line input: 14.5 Ohms Imaginary part of impedance at line input: 24.1 Ohms At 1,500 watts, maximum rms voltage on line: 576.7 volts Length from line input for peak voltage = 1.64 ft Maximum rms voltage rating of cable: 1400 volts Choose another Frequency (F), Zant (Z), or Transmatch ([T]).
