DCF77 reception inside buildings is possible, but reception quality may be impaired by the shielding and
attenuation effects of the walls.
Factors that can impair reception:
•
Installation of the antenna near metallic objects (e.g., reinforced concrete walls, metallic wall coverings,
thermal insulation, glazing, etc.)
•
Installation of the antenna near televisions or computer monitors
•
Installation of the antenna under or near power lines
Meinberg Funkuhren recommends installing the antenna outdoors. Doing so will generally have the advantage
of maximizing the distance of the antenna from sources of interference, thus improving the signal-to-noise ratio
and significantly increasing the chances of successful synchronization.
Installation conditions for optimum operation:
•
The antenna should be installed horizontally
•
The length of the DCF77 antenna unit should be perpendicular to the direction of the transmission tower
(see example map on previous page and label on AW02 antenna)
•
The antenna should be at least 30 cm away from any metal objects
If these installation criteria cannot be met, signal reception may be
impaired.
