Hi,
we are going to install a satellite dish system on our townhouse and want to get a rafter mount for it. According to the carpentry company, the rafter spacing is no more than 1 meter (3.3 feet), so we will use the Herkules 48/900 B model, as it supports rafter widths up to 120 cm (47 inches).
But how exactly does this work? Is this usually done by the roofer if agreed with them in advance (I have already sent an email to ours and am waiting for a reply), or can it safely be done by ourselves? This surely needs to happen after the roof has been covered, removing the relevant roof tiles to attach the rafter mount, right? We have also ordered a special roof tile designed for satellite installations. Running the satellite cables is another issue, as they need to pass through the roof as well. Maybe someone could kindly explain the approximate procedure.
Thank you very much

If you install it on the wall, no equipotential bonding is needed. General statements like this are usually incorrect, and this one is no exception.
Facade antennas that are not mounted within the designated safe facade areas must be grounded like roof antennas with a lightning current-resistant conductor of at least 16 mm² (25 mm² (40 mils) copper, 50 mm² (100 mils) steel/zinc-coated) and connected to the equipotential bonding system.
According to the current DIN EN 60728-11 (VDE 0855-1):2011-06 standard, the previously mandatory equipotential bonding is now optional if the following conditions are met:
Starting from a Quatro LNB, the limit for leakage currents can already be exceeded. Therefore, without the ability to measure leakage currents, it is recommended to install equipotential bonding, typically using 4 mm² (12 AWG) copper conductor, even when antenna grounding is not mandatory.
Grounding and equipotential bonding are integral parts of the electrical system and installations must comply with NAV § 13. However, not every electrician licensed by a network operator for low-voltage installations is necessarily an antenna specialist or qualified regarding lightning current-resistant grounding and equipotential bonding.

It should of course have said 25 mm² (38.7 in²) aluminum.tecker201011 Aug 2016 20:34Do you always copy this directly from a textbook?
