BCS121 antenna
The cable of the supplied DCF77-antenna can be extended without any problem (up to a
maximum of 100 meters, 300 feet). Mount the aerial in a position where reception quality of
the DCF77-transmitter is good. Be aware of the fact that the direction of the antenna is
important. If the reception of the transmitter is good, the LED on the aerial will blink every
second on a regular basis. If the LED doesn't blink, or blinks irregularly, reception is bad. The
cause for a bad reception can often be found in computer-equipment nearby, or steel
constructions in the building, blocking the long-wave signal of the transmitter.
CAUTION:
The supplied antenna is not suitable for outside-mounting. The antenna is not
waterproof, and the built-in electronic circuit will not operate properly below the freezing point
and above 50 degrees Celsius.
