Types of RP-SMA Connection

So many of you may run into issue on types of SMA or RP-SMA Connector.  Some miner uses different type of connection.  For example: RAK Miner uses "RP-SMA Female"  and the antenna end that connects to the miner is "RP-SMA Male"

For Example: RAK Miner: The miner end connector is a RP-SMA Female.  It has an extra center needle.  So the corresponding connector will be RP-SMA Male.

This is the corresponding end that uses RP-SMA Male.  No Center Pin.  Pretty confusing if you ask me, when we think male, should have center pin.

Another example: Dragino Miner, uses "SMA-Female" This one have no extra center pin.  So the corresponding parts is "SMA-Male" which will have a center pin. 

Here's a simple cabling flow diagram that shows the cabling flow using our antenna kit + extension cable.
