MY Tolemai installed our smaller X2 DOME which has 8 antennas, 2 panels/modems, and a control router. The X2 DOME is meant for yachts up to 30- 35m as such yachts usually have fewer guests onbaord, thus fewer bandwidth requirements. Just like our original X4 DOME – it is an easy self-install and takes only a few hours. Sanlorenzo, 34m
