Difference between SMA and RP-SMA connectors
If you wondering what is the difference between a SMA and RP-SMA connector and which antenna you should choose for your transmitter or receiver, here is my short and clear answer:
The RP-SMA connector is a variation of the SMA connector and has the same external housing. The only difference is the gender of the interface, but that also makes RP-SMA and SMA connectors incompatible with each other.
For better understanding, check the picture below.

As you can notice, you can not use the one type with the other, so before choosing a new antenna or video transmitter, always look at the connector type. Hope it is more clear now 🙂
* Jack is also called a “female” and plug a “male”.
