The difference between the two Office 100 50 Ohm kits is the included antennas.
The Office 100 50 Ohm Yagi/Panel is kitted with an outdoor yagi antenna and an indoor panel antenna. Due to these antennas’ characteristics, this kit is best for small businesses far from cell towers with weak outside signals.
The Office 100 50 Ohm Omni/Dome is kitted with an outdoor omnidirectional antenna and an indoor dome antenna. Due to these antennas' characteristics, this kit is best for plug-and-play applications and decent outside cell signal environments.
