TV-reception antennas for VHF are constructed with cross
Chapter 24, Problem 24(choose chapter or problem)
TV-reception antennas for VHF are constructed with cross wires supported at their centers, as shown in Figure 24.27. 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?
Figure 24.27 A television reception antenna has cross wires of various lengths to most efficiently receive different wavelengths.
