4x4 antenna mimo
For Roof Mast mounted direction gain log periodic antennas…
MIMO 2x2 is two antennas 2 to 3 feet apart (vertically or horizontally from each other where one antenna is polarized at -45 degrees from vertical and the other is +45.
OK. Then what are mounting, separation and most important the polarization angle for 4x4 MIMO?
Would that be (Vertical, Horizontal, -45, +45)? What is a reasonable CTR2CTR distance?
Application is a FIOS failover solution using 4G LTE carrier aggregation in a low signal area. The CAT-18 is using 4x4. I need a bunch of gain, so a prefab single antenna is not going to work.
What the actual antenna spec best practice for roof mount directional gain units for 4x4 MIMO?
Thanks in advance.
