I put 5 even though...

If you already have a good antenna because you are in a bad signal area (e.g. Televes DAT-75 T-Force 5G LTE HD), the antenna with its own PASSIVE amplifier, i.e. WITHOUT POWER, has a gain of 19db, or if you have a very good antenna with an ACTIVE amplifier and power, IT IS USELESS AND WILL OVERLOAD/DAMAGE THE SIGNAL. The antenna is sufficient with a power supply that provides 40db gain. If you install an amplifier, it should either be set to 0 in terms of gain intensity or a technician should come with a field meter, etc.

There is a possibility that if you have a Televes DAT-75 T-Force 5G LTE HD antenna, the amplifier may short-circuit the antenna's circuit board and nothing will be visible. In our case, the amplifier worked ONLY after we installed a power supply (Televes Picokom Easy-F 24V 2out Power Supply).

The first amplifier had psychological issues that were not even noticeable at the MISTRAL factory, even though they are all great and they gave me a new one that worked properly and I informed them.

Personally, I regret not getting a TELEVES amplifier so that all the components, especially the circuits, would be 100% compatible.
