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.

What Others Are Asking

Do ICs have a shelf life?

What I would like to know is if ICs also have a limited shelf life and if so, do some types suffer more than others?

What will go wrong when it is stored at a higher temperature or past its shelf life?

Solder paste should be stored in a refrigerator and it has an expiration date. But what exactly will go wrong when it is stored at a higher temperature or past its shelf life?

Why do newer devices lack external antennas?

Technology got better: sensitivity increased, antenna design got better so patch antennas (integrated with PCB or integrated with the case) became not just practical but
