Hi
is there a 5G capable antenna coming soon, currently holding off for a new antenna, ps to this I have seen posts and specs that you can argrate bands up to 300Mbs.. but the ethernet port on the antenna is 100 Full? what gives.. no point unless it gives more stability,
You should search your country vendor for lte antenna.
Some RB have FastEthernet ports, others Gb, check a mikrotik.com/hardware in LTE subcategory
