Here are some key features of both amplifiers: * 60W output power * 34 dB small signal gain UHF, 36 dB VHF * 12V enable pin for on/off control * Integrated harmonic filtering * SMA input, N-type output Using these we should get a link margin of ~19 dB for APTAS which in turn should give us less than 10^-10 bit errors per second on telecommands. Please feel free to raise objections or give feedback. From Rickard Nilsson I would like to hear if you are interested in joining the order with us so we get 2 of everything?
