Wall Installation

Selecting the Appropriate Wall Mount

For wall installation, the satellite antenna is mounted to the exterior wall of a building using a wall bracket.

Depending on the size of the satellite antenna, appropriately dimensioned wall mounts are available. Naturally, a large 85 cm dish requires a significantly more robust bracket compared to a 33 cm mini antenna.

Determining the Required Wall Clearance

In addition to the antenna size, the installation location is also critical when choosing the right bracket.

It is important to determine the necessary wall clearance for the bracket. This depends on the orientation of the wall in relation to the azimuth angle—that is, the required horizontal alignment of the satellite antenna. Two limiting cases apply:

First, if the azimuth direction is perpendicular to the wall, the reflector (dish) of the satellite antenna can be mounted parallel to the wall, resulting in the shortest possible wall clearance. In this case, a short bracket is sufficient.

However, if the wall runs parallel to the azimuth direction, the reflector must be positioned perpendicular to the wall. This results in a required wall clearance that is at least half the diameter of the reflector.

Considering Roof Overhangs

The roof overhang must also be taken into account during wall installation. It must not obstruct the antenna’s line of sight.

The closer the antenna is installed to the roof overhang, the more likely it is that the overhang will interfere with signal reception. If the antenna is poorly positioned, the roof overhang can become a significant obstacle, severely affecting reception.

For installations near large roof overhangs, both the horizontal and vertical alignment of the antenna should be carefully considered.

If it becomes evident that the overhang is obstructing the antenna’s view of the satellite, this issue can be resolved by using a wall mount with greater clearance or by mounting the antenna lower and farther away from the roof overhang.

Choosing Suitable Dowels and Screws

When attaching the wall bracket, it is essential to use dowels and screws appropriate for the masonry and capable of withstanding the required loads.

In general, only stainless steel screws—preferably in A4 quality—should be used outdoors. This not only prevents unsightly rust stains on the façade but also ensures long-term durability by eliminating corrosion.

Cable Routing

The antenna cable is typically routed into the house by drilling a hole of suitable diameter into the masonry. Care must be taken to ensure that the cable(s) are positioned to prevent rainwater from running into the wall. To achieve this, the cable should be laid in a downward U-shaped loop—referred to as a "drip loop"—before it enters the wall. This ensures that water drips off at the lowest point of the "U" and does not continue into the masonry.

Note: Grounding Not Required
For wall installations, grounding of the satellite antenna is generally not required. According to DIN EN 60728-11, grounding is not necessary if the antenna is mounted more than 2 metres below the edge of the roof and no more than 1.5 metres from the building. If in doubt, consult your local specialist dealer for guidance.
