Banana Pi Router design BPI-R4(MT7988)

:wave: Welcome All …

This discussion is for sharing experiences with 5G and 4G :satellite: antennas. I’m using the BPI-R4 as a 5G router (Module m.2 Quectel RM551,RM520, Fibocom FM350), which has four antenna ports.

I’ve tried several types of antennas from AliExpress but haven’t had much luck finding one with genuinely good gain. Many sellers advertise high gain (around 12 dBi), but the actual gain is often closer to 4 dBi.

I’d appreciate any recommendations or links to reputable AliExpress stores that offer quality 5G/4G antennas with reliable gain (Like 8 DPI or 12 DPI or 15 DPI).

You don’t need any antennas, what you need is to place the Quectel modem on an 5G M.2 to RJ45 (RGMII) and then place it outside your home on an Outdoor PoE Antenna Enclosure and only use the BPI-R4 as a wireless router inside your house.
