How can I separate PCB antenna and SMA connector?

I am designing a prototype PCB for a Lora node. It will have an SMA connector (J2) and a PCB antenna. Switching RF connectors are not available in my area, so as an amateur enthusiast what is a good way to separate the antennas?

They usually put a 3-pad solder jump.

The central pad is connected to the LORA integrated circuit.
The left pad is connected to your SMA connector.
The right pad is connected to the printed antenna.

How can I fix my “D” key that sometimes isn’t responding when I click on it?

My mechanical keyborad is brand new so I cannot find where the culprit is. How I fix the key?

What will be the role of a copper layer in a metal core PCB in thermal dissipation?

In the design of a power electronic PCB, I want to use a metal PCB for heat dissipation of a TO-220 package MOSFET. To do that I want to mount metal PCB on the MOSFET with the use of thermal paste and screw exactly like we do when we use heatsink for the same package. Should I leave the copper of PCB between MOSFET surface and dielectric of PCB or remove the copper surface and leave only the dielectric opening?

Is paste mask layer, both top and bottom layer, necessary for THT components?

I know the paste mask layer is also called the stencil layer. It’s only used for assembly. I want to know if the paste mask layer (both top and bottom layer) is necessary for through hole components. For SMD components I know the paste mask layer is required to solder the components. Is it necessary for through hole components?
