The DF-88A Direction Finder provides all the benefits and varied usage of a direction finding system, while offering a design that is both practical and functional

Like all permanently installed EBC DF units, the DF-88A is connected directly to your existing aircraft radio. It allows the pilot to accurately and easily home in on any signal that can be received on any aircraft transceiver.  The indicator needle tells the story – turn right, turn left, fly straight  —  it’s just that simple! In addition to its usage in search and rescue operations, the DF-88A has found wide acceptance among private pilots, offshore helicopter operators, law enforcement authorities, fishing fleets and others.

One reason the DF-88A is unique is because it is so practical. It enables the pilot to save on valuable antenna mounting space by removing the existing COM antenna  The antennas which are supplied with the DF-88A also perform the receive and transmit functions of the COM antenna. The DF-88A antennas frequently provide better performance than the original COM antenna.  Through its interconnection with the “push-to-talk” line from the pilot’s microphone, the DF-88A automatically switches out the DF circuitry allowing the pilot to transmit normally without damaging the sensitive DF circuitry.

The DF-88A – practical…functional…and affordable! Available in either the VHF or UHF Aircraft Band or Business Band. Comes complete with amplifier, indicator, antennas and all necessary connectors.
