HD video transmission and reception system having 12-15km range multi-transmitter one receiver

Do you have a product or solution for this requirement?
I wanted to know if you had any solution/product for an HD video transmission and reception system having about 12-15km range. Additionally, we are planning to establish a Multi-point to point system wherein multiple transmitters would need to transmit to a single receiver (Max. Number of transmitter nodes: 10-15). I would like to further discuss this requirement and would love to hear from you

Our engineer recommended the below models to meet your requirements.

We also have a test video on youtube. (from mountain top to the seaside, 27km)

1. For one transmitter to one receiver, 10km, 2W power amplifier is ok.
IP camera, RJ-45 net cable, Transmitter, Receiver, two nodes for one full set transmission is needed.

2. If your camera is HDMI or SDI, then HDMI encode on the transmitter and HDMI decodes at the receiver is necessary.
HDMI-1080P Encoder
HDMI-4K Encoder
HDMI Decode

3. For multi-transmitter to one receiver, 10km, we suggested that you choose the 10W Power amplifier.
10~15 air transmitter (12~15km), 1 receiver at the ground.
The wireless part: 10W Power Amplifier is needed, it is estimated that the total code stream from multi-transmitter to the ground receiver is 15~20Mbps, so when there are 10~15 nodes, the average code stream of each is 15~20M per node, that is, the code stream from each air terminal to the ground terminal is 1~2Mbps, and H265 1080P video can also be transmitted.
