In $1957,$ the $($then$)$ Soviet Union launched Sputnik, Earth$$s first orbiting artificial

satellite. Sputnik orbited at an altitude of $134($perigee$)$ to $583($apogee$)$ miles. It

transmitted with approximately one watt RF power at frequencies of $20\mathrm{.}005$ and

$40\mathrm{.}002$ MHz$.$ Sputnik had two pairs of antennas with elements in each pair that

were $2\mathrm{.}4$ and $2\mathrm{.}9$ meters. Since the operating frequencies corresponded to

wavelengths of $15$ and $7\mathrm{.}5$ meters, the antennas were not resonant at either

operating frequency. Assume the antenna gain at each frequency was about $0$

dBi. Sputnik transmitted alternating $0\mathrm{.}3$ second pulses at each frequency
