- TV-reception antennas for VHF are constructed with cross wires supported at their centers, as shown. The ideal length for the cross wires is one-half the wavelength to be received, with the more expensive antennas having one for each channel. Suppose you measure the lengths of the wires for particular channels and find them to be 1.94 and 0.753 m long, respectively. What are the frequencies for these channels?Example The normalized radiation intensity of an antenna is defined by U(0) = sin(0), Find the: b. FNBW a.
