Because we had to work with a "high density" connector for the AIR COM due to its extremely compact design, the pins of the connector can only accommodate cables with a maximum diameter of AWG22.
Due to the fact that a relatively large amount of current has to flow through the relatively small pins during transmission, we recommend using two pins each for the power supply for plus and minus. It is recommended to use pins 1 and 10 and 5 and 6 together.
Typically, an AWG22 cable is inserted into the two pins as a bridge and this "bridge" is then connected to an AWG20 cable (called a splice).
