Think of it this way. It consist of two identical metal rods which are separately fed using two different wires or feed lines. In case your router has 3 antennas you can place the middle antenna straight upward. Due to PCI cards coming with antennae, this makes them naturally better at picking up a stronger signal than USB adapters. For this to happen, the access point has to have MIMO also. I put one antenna I had available to me on one of the RP-SMA connectors on the adapter card at the back of the computer, just to test if it was working. These days you need USB ports for just about everything and if you use a USB wireless adapter then you will permanently take up one of these precious slots. You cannot say the same about a USB adapter. A command and control server (C&C server) is a computer that issues directives to digital devices that have been infected with rootkits or other types of malware, such as ransomware. An Intel wireless card most likely will not work in your notebook because it has AMD hardware, so that is why I don't recommend you risk getting an Intel card on a 90% probability it won't work, where there is a 100% probability the Broadcom cards will--as long as your notebook has 2 antennas to connect to the card.
