Since some pre-amps aren't powered off the coax, but rather\nfrom a separate pair of pins, I was wondering if you can use a bias-tee AT\nTHE PRE-AMP to extract the DC voltage off our coax for connection to those\nexternal power pins on the pre-amp?\n\nRunning a separate cable to power the pre-amp is not the end of the world,\nbut it would be convenient if I could turn on the bias voltage available on\nthe Airspy or RTL-SDR and then extract it up at the antenna to power a\npre-amp.\n\nThanks for any recommendations!\n\n-Scott, K4KDR\n", "attachments": [] }
