$25 VHF UHF RF Power Amplifier

Here is an amplifier that you can buy on Amazon for $25 and covers the frequency range from 1MHz- 700Mhz... with a claimed output power of 3.2 W and 35 dB of gain. I measure the power output with a Bird RF Power meter, and look at the spectrum with and a tiny spectrum analyzer. This little amp is great for so many mad science experiments!
