- jacquesm 9y agoGain is effectively the same as amplification, any kind of gain achieved in a passive manner indicates some kind of directional compromise. It also should work equally well when receiving and transmitting, whereas an amplifier would work for only one direction (so you'd need two, one to output more power, another to amplify the received signal).
- walshemj 9y agoBut technically there are legal maximum emitted powers unless you are "a professional"
- jacquesm 9y agoFortunately the legal maximum is total radiated power and not 'power radiated in one particular direction'. I did some pretty interesting stuff with 19 element Yagi's and very low power transmitters.
