Today, I’ve been testing my second gateway, a Rak2243 on a Raspberry Pi (using the Rak-image) and a DeLock 868MHz antenna:
It performs around 30dB worse (tested with an Adeunis field tester and the site lorawantester.com).
For the RAK831, i use SMA connectors and a GSM antenna:
For the Rak2243, i bought RF240 cable and crimped N connectors to it.
Do you have any idea?
