Description
DCF77 Optical Antenna Link


The DOAL/A module mounts indoors, and connects to a Meinberg DCF antenna (AI01, AW02 or AK03) with a short coaxial cable. The DOAL/R module connects to the receiver's antenna input either directly or with a patch cable. Both modules are linked to each other by a single GI50/125μm or GI62.5/125μm multimode gradient fiber. This Fiber Optic connection provides several advantages:

The DOAL system is suitable for all Meinberg DCF receivers, and can be retrofit to existing Meinberg DCF77 systems. The DOAL/A antenna module requires an external power supply to operate the DCF77 antenna. The DOAL/R receiver module is powered by the DCF receiver and does not require an external power supply.
