Thanks for your answer.
I'm looking for a solution for a caravan. At the most time the Internet-connection is over LTE, but sometimes is a free hotspot via WiFi available (some campsites). For booth connections I want to use a outdoor-roof-antenna. Is it easy to switch between these two connections, or automatic by failover?
When I use external antennas for WiFi for better reception, than was send the internal WiFi also via the external antenna, or is there an internal antenna in the router?
Best regards
Lutz
