Example: wavelength of a 200MHz wave = 300,000,000 / 200,000,000 = 1.5 meters
Example: wavelength of a 380MHz wave = 300,000,000 / 380,000,000 = 0.79 meters
So my lecher line needed to be at least 0.79 meters and at most 1.5 meters. Actually, a lecher line that is half the wavelength will work too if you're short of wire. Mine was only 1.12 meters.
