If you are after the cheapest and smallest spectrum analyzer possible look for a TV tuning USB dongle. Some of these tune over the range of 64-1700 MHz There is software to do FFT and plot spectrums You can set started plotting in the UHF range for $20.
It is a bit do it yourself in that you likely need a selection of attenuators and and so on because the dongle expects the signal level of a cable TV or TV antenna and the bandwidth is not DC to GHz. But the cost is right.
