[QUOTE="Vipersan, post: 972759, member: 325666"] The only problem I can see is powering the LNA close to the Helical ...as the one closest to the receiver would have its input cap coupled ... Possibly a spur could be taken from the ghost powered LNA to the more isolated LNA to supply it's 5v ...assuming of course the current drain on Airspy would not be excessive .. Next question ..is regarding the filter ..which if 'active' would also need a supply.. [/QUOTE]
