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.

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

What Others Are Asking

Is there any problems if I change 0805 too 0402 surface mount or smaller?

In order to reduce the size of a PCB, I will probably have to use smaller SM components. I currently use mostly 0805 passives, and am thinking about going to 0402 or smaller. Apart from power dissipation considerations, any pitfalls I should be aware of when making the transition?
