3.6 Figure P3.6 shows a dipole antenna. It is very effective in receiving television signals when its length is approximately equal to one-half the signal wavelength. What are approximate antenna lengths for receiving signals for the following: (a) Channel 2 (f = 57 MHz) and (b) Channel 13 (f = 213 MHz)?

Step 1
The wavelength (\(\lambda\)) of a signal is related to its frequency (\(f\)) and the speed of light (\(c\)) by the equation: \[ \lambda = \frac{c}{f} \] where \(c = 3 \times 10^8 \, \text{m/s}\). Show more…

TV-reception antennas for VHF are constructed with cross wires supported at their centers, as shown in Figure 24.28 . 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 $\mathrm{m}$ long, respectively. What are the frequencies for these channels?
A television is tuned to a station broadcasting at a frequency of $6.60 \times 10^{7} \mathrm{~Hz}$. For best reception the set's rabbit-ear antenna should be adjusted to have a tip-totip length equal to half a wavelength of the broadcast signal. Find the optimum length of the antenna.
