My indoor setup is: An older Dell laptop E6420 with an i7-2640M CPU, running Ubuntu 19.10, Airspy R2 receiver dongle, bias tee fed from an step-adjustable power supply, gas lightning arrester, RG6 cable to antenna outside (45 meter of cable).
My antenna setup is FA antenna, RTL-Blog LNA, grounding electrode pounded in the soil (only 4 ft long) and ground wire. I was concerned about bringing a lightning strike in the house.
