Hi, I have low GSM signal: howto I can improve it?

I can change antenna? Which Antenna I have to use?

lewisxhe commented 1 year ago

The GSM operating frequency range is generally 850, 900, 1800, and 1900 MHz. You can buy the antenna that supports the corresponding frequency band to replace it in exchange for better signal

I can choice any gain? It can damage hardware of LILY board?!

It support FPC and PCB type antennas?

the only constraint is the type of connector?

The only restriction is only the connector type, and nothing else matters
