GIRA System 55 - Supplier of network sockets and antenna socket

Hello,
we would like to use the System 55 from Gira for our new building.
Who can tell me types and manufacturers of alternatives to the Gira sockets (very expensive)? These should also fit....
It is about telephone sockets, TAE, network sockets, and antenna sockets.
Best regards Christian

They have everything that the usual hardware store has to offer.

Is there nothing to be considered there?
Which manufacturers / types can be recommended online?

Well, you only need to pay attention to the standards CAT 6a etc., or in the case of satellite sockets, for example, use end sockets.

For example, I use BTR for network and Axing for SAT.

Hello
I have installed the following:

Sat socket:
Delta SEA 2400

LAN socket
Rutenbeck

A few days ago I installed network sockets, some random ones. They were double sockets, but I won't touch anything other than Rutenbeck anymore.
