Hello,
The antenna selection depends on environmental factors. The higher the dBi number of the antenna, the higher the gain, but less of a broad field pattern, meaning that the signal strength will go further but in a narrower direction. Higher gain is not automatically better - it depends on the application. If you do not intend to point the antenna in a particular direction, then no need for much gain but if you intend to point the antenna in a particular direction then need to choose antenna with a higher gain.
I would advise you to take a look at our outdoor routers OTD140 or OTD500. Both are IP 55.
OTD140 Antennas specifications: 2 x 698 - 960 / 1710 - 2690MHz, 50 Ω, VSWR <3, gain <4.5 dBi, omnidirectional
OTD500 Antennas specifications: 4 x 617 - 960 / 1695 - 2690 / 3300 - 4200 / 4200 - 5000MHz, 50 Ω, VSWR <3.5, gain <4.9 dBi, omnidirectional
Also we have these outdoors antennas for RUT9, RUT2 series, RUTX50 and RUTM50, the same as for the RUT X11 and RUTM11 routers:
OUTDOOR LTE/WI-FI/GPS ANTENNA FOR RUT9-SERIES ROUTERS
OUTDOOR LTE & 5G/WI-FI/GPS ANTENNA FOR RUTX50 AND RUTM50 ROUTERS
OUTDOOR LTE/WI-FI/GPS/BLUETOOTH ANTENNA FOR RUTX11 AND RUTM11 ROUTERS
OUTDOOR LTE/WI-FI ANTENNA FOR RUT2-SERIES ROUTERS
