Has someone tried this amp?
It is advertised as a 2-W amp. If this is true, it would be quite convenient to mount the device right at the focus of the dish, because it looks much smaller thant the usual wi-fi booster, and maybe more weather-resistant with its shhrinked-plastic cover.
They claim 11dB Tx gain (and 10dB Rx gain) and require a 3.7-5.5V supply. Input power is +4 to +20dBm.
I suspect they'll run quite warm but it doesn't look too hard to strip off the heatshrink cover and attach a heatsink.
