MR6400 with external antenna
I'm planning to buy the MR6400 router for use with an existing 3 network Data SIM. I live remotely and currently own a Poynting XPOL-1 external Antenna which i would like to reuse. An exteranl antenna is very necessary where i live.
Can anyone advise whether these are compatible. I am concerned that the Antenna is too old and will not give me 4G or optimium strength. On Amazon there is a bundle being offered of the Poynting XPOL-1 V2 5G 3dBi Omni-Directional Cross Polarised LTE 2x2 MIMO Outdoor Antenna & TP-Link TL-MR6400 300 Mbps 4G Mobile Wi-Fi Router, SIM Slot Unlocked. Should i upgrade the Antenna?
Thanks, in anticipation of your advice.
