directional antenna deployment question---why signal on the feeder side is weaker than the opposite side?

    Hello everyone
    The problem I have now is that the signal on the feeder side is weaker than the signal on the opposite side when doing the streaming test, the AP uses 534, and the directional antenna uses AP-ANT-45 and AP-ANT-48. The height of the directional antenna from the ground is 2.614m, and the deployment method adopts ceiling deployment.
    I am now using ixchariot streaming software to test, the distance between APs is 28 meters, no blocking, each AP is connected to a single or multiple terminals, and the distance between terminals and APs is different.
    Question 1, what is the correct way to connect the feeder to the AP, because I found that there are 1-4 labels on the feeder, and 0-3 pin numbers on the AP. Impact.
    Question 2: Is there a more reasonable opinion on the placement of the directional antenna?
    Question 3. The directional antenna adopts the ceiling-mounted deployment method. Is it normal that the signal on the feeder side is weaker than the opposite side?
    Note: The feeder side refers to the A direction, and the opposite side refers to the B direction.

    Directional antenna is meant to be install on walls/poles vertically to allow beam pattern going horizontally.  AP-ANT-45 had 90 degree beam width and AP-ANT-48 has 56 degree (5GHz)  and 70 degree (2.4GHz) beam width.  In a office environment ( like  on your photo) , better to use omni directional antennas or   AP-535 with built in omni.
