All: Received my LTE-Lite and ready to play, EXCEPT, I'm in the basement. Does anyone know if the antenna which the ebay purveyor of the Nortel Thunderbolts supplies will work on the 3.3 volts coming out of the LTE Lite? (I measured the Nortel, it puts 4.95 volts on the coax.) That

Hi Jim, not much harm should come to the 5V antenna if driven at only 3.3V. However if you feed 5V into the LTE Lite antenna port then bad things will happen because it will back-feed into the 3.3V power rail, and possible damage some of the 3.3V parts on the PCB. Running a 3.3V antenna
