16 <H1>Arguments and options for <CODE>design_coupler</CODE></H1>
17 If<CODE> design_coupler</CODE> is run with the wrong number of arguments (there should be 3), it prints information on what it expects for its 3 arguments and the options available. .

21 Usage: design_coupler [-d] -[e] [-q] [-s fstep] [-C] [-H height] [-L length] [-Z Zo] CF fmin fmax
23 CF is the coupling factor required in dB [10 log(P1/P2)]
24 fmin is the minimum frequency (MHz)
25 fman is the maximum frequency (MHz)
27 -d Calculate physical dimensions (takes a while).
28 -e Give lots of examples of usage.
29 -q Run in quite mode, giving less output.
30 -s fstep Set the analysis frequency step in MHz.
31 -C Print Copyright, Licencing and Distribution information.
32 -H height to set the height of the enclosure (defaults to 1 unit).
33 -L length to set the coupler length (m). Defaults to lambda/4.
34 -Q Run in very quite mode, giving just one line of output
35 -Z Zo Set the design impedance (default is 50 Ohms)
