+# calctenna
+
+## calculate dipole antenna leg length
+
+```
+usage: calctenna.py [-h] [-f [frequency]] [-V [velocity_factor]] [-q]
+
+optional arguments:
+ -h, --help show this help message and exit
+ -f [frequency], --frequency [frequency]
+ Desired frequency in Hz
+ -V [velocity_factor], --velocity-factor [velocity_factor]
+ -q, --quiet print only result
+```
+
+### Example output:
+
+```
+$ calctenna.py -f 104e6
+Desired Frequency: 104e6 Hz
+Wavelength: 2.883 m
+Wavelength / 2: 1.441 m
+Wavelength / 4: 0.721 m
+Velocity factor: 0.951
+-> Dipole leg length (lambda/4): 0.685 m
