Lone Star Aviation’s 100 amp filter (FEED THRU) (Fail Safe Design) attenuates both low and high frequency, (10hz to 30 mhz) of EMI-RFI noise generated from the aircraft’s alternator systems to the aircraft’s dc buss. This noise interference travels from the a/c buss to critical on board GPS navigation, RF, audio, storm scope systems. This filter, (100 amp Fail Safe design) is used by OEM aircraft manufacturers to attenuate 100% of the on board noise before it penetrates the aircraft’s dc buss. The filter is FAA- PMA pending for certificated aircraft but can be used on experimental aircraft
Yes, this filter is FAA / PMA.
