ᐅ Is a Satellite System Still Necessary for New Builds, or Is IPTV Sufficient?

Hello everyone,
Please forgive me if I haven’t searched through hundreds of pages. My basic question is whether you still consider a satellite dish necessary or if you would just skip it altogether. About our profile: When we watch TV, it’s exclusively public broadcasting channels and no private channels. However, mostly we watch on-demand content like Netflix, Amazon Prime, and so on. In this context, we’re really starting to doubt whether we can save ourselves the 850 EUR gross. What do you think? Should we just stream the public broadcasting channels via Apple TV, or is it still better to have a satellite dish installed?
Thanks & good luck, Commanderchen

I consider this a very dangerous half-truth at best. Grounding and especially lightning protection for antennas—even offset antennas used for satellite systems—are a complex topic that, in my experience, very few electricians truly master, let alone amateurs. As long as nothing happens, nobody cares, but the consequences can still be devastating in case of an incident. For me, this is another reason to avoid satellite systems.
(I’d rather not ask about the proper implementation by @Andre77.) Anything located more than 1 meter (3 feet) below the roof edge does not require grounding. Although it makes sense, it is not a legal requirement.
Lightning protection (lightning rods) is a different matter altogether. I have never seen an installation where the system on the wall had a lightning finial. However, this should be handled by specialist companies.
I mentioned grounding/potential equalization.

Anything more than 1 meter (3.3 feet) below the edge of the roof does not require grounding.That is not entirely correct, as you can easily find by searching for the terms "lightning protection satellite system" on Google Images, for example. External lightning protection can be omitted if the dish is installed at least 2 meters (6.6 feet) away from the roof edge and no more than 1.5 meters (4.9 feet) away from the exterior wall. To my knowledge, this includes grounding and not just the lightning rod.
I believe the rule about one meter below the roof edge is incorrect. At least, I have only ever read about two meters (6.5 feet), but there are also a number of other conditions that must be met. Additionally, the potential equalization at the antenna itself is just one of several points to consider, which is why I would always have this work done by qualified professionals—and in 99 out of 100 cases, not by a general electrician without specific expertise.
For this, the user @Dipol can explain everything in detail. He knows all the nuances in this area.

For grounding and equipotential bonding (EPB) of antennas, the guidelines of IEC 60728-11, German classification DIN EN 60728-11 (VDE 0855-1), are primarily applicable.
The changes that have occurred over decades have remained essentially stable and comparatively easy to overview, unlike other parts of the standards series for antenna systems. This makes the lack of knowledge among many electrical contractors, my fading community of RFT technicians, as well as some electrical contractors and IT specialists, all the more incomprehensible.
Competence is certainly not gained by making sweeping verbal attacks against standards you have not yet familiarized yourself with. Installing antenna systems in compliance with standards is not rocket science.

As I already mentioned, sometimes a set-top box is required, I’ve seen that before, and it looked great.
Unless the provider offers the signal as DVB-C, then you’re just happy to get all channels in HD without extra costs, which I have to pay anyway for reception. You pay once for the satellite system and that’s it.Well, sometimes you need set-top boxes for satellite as well. Instead of IP set-top boxes for older TVs, you can also use Android TV sticks that cost around 50€ (about 55 USD).And don’t you also need a monthly subscription for HD+ with satellite? Also, satellite components don’t last forever...
