Capacitor near antenna connector broken

Issue:
After two years of normal operation I noticed poor reception performance.

Setup:
DIY LoRa GW eith Raspberry pi zero

Server:
TTN

Details:
After visual inspection I noticed broken capacitor between Natenna connector and RF input. There are two capacitors in series and I would like to replace both. I can’t find detailed schematic of the RAK831 module and I can+t measure the capacitance of broken capacitor. Whati are specs for both capacitors?

Hi @Jeff , Can you provide some help?

Hi Marko,

Please refer to the SCH.C234 and L204 are 56pF capacitors(0402 package).

DearJeff, thank you for the support. Caps are replaced.

Will report the field test results.
