The Huawei 5G CPE Routers, do not have 4 External Antenna Ports, has this been Modified or are you using Cable Splitters?
The Standard Huawei 5G CPE that do have External Ports (From the Factory) only have 2 External Antenna Ports and these Ports do not cover the Bandwidth of 698-3800 Mhz, they only cover frequencies around 3.5Ghz, so typically 3300 to 3800 Mhz or up to 4200 Mhz for China Versions, so in the EU/UK this will only really cover 5G NR Band n78.
For the above reason the Factory Standard Antenna Ports will not cover EE 5G NR Bands n1, n3, n7 and n28, neither will the Ports cover any 4G Bands, so these Bands will need to be pulled in using the Routers Internal Antennas (so a mix of both Internal and External Antennas).
On a Standard 2 Port Antenna Huawei 5G CPE, the External Antenna configuration is 2x2 Mimo on 5G n78, or 4x4 Mimo at that frequency if the Internal Antennas can also receive a n78 Signal and the correct Antenna Settings are selected or set to Auto.
On 2x2 Mimo (and 4x4) the External Antennas should be Polarised at 90 Degrees to each other, ideally with 45 Degree offset from normal Vertical and Horizonal, so each Single Antenna will be +45 Degrees and -45 Degrees (ie 90 Degrees between them) some Antennas do this inside the Aerial Enclosure or Housing (sometimes called X polarised) whilst some do not and rely on manual adjustment or tilting.
Your table of A1 to A4, doesn't really follow the normal, and do not appear to be in the correct order, how are these Antenna Ports connected to the Router?
