Mikrotik LHG 4G Kit. Speed Problems

734/5000
Hi. I recently bought a Mikrotik LHG 4G Kit (LHG R + R11e-4G modem).
I can not exceed 16Mbps download speed!
Update Frimware to the latest version 6.46.4!
Update the modem Frimware to the latest version R11e-4G_V007!
I still have the same problem.
I have direct visibility with the cell tower.
It operate in Band 3 LTE 1800Mhz.
I have a Huawei B525 Router with two 15 meter coaxial cable and two Yagis antennas located exactly the same as the miKrolik.
With my Huawei Router I reach download speeds of 70Mbps.
I don’t understand what the problem may be.
Could it be a problem with the LHG R antennas?
This problem would be solved if I change the R11e-4G modem for another R11e-LTE6? Would this unit support change?

I would really like to know what is going on. I am using an LHG LTE with much success and our tower is almost 3 miles away and when it’s quiet I’ve seen close to 90M down.

manufacturer: MikroTik
model: R11e-LTE-US
revision: MPSS: R11eL_v16.02.183961 APSS: R11eL_v05.03.183961

I did just pick a an LTE6 LHG and will be testing it this week to see if we can get better speeds.

I’m going to change the LTE card to R11e-CAT6. If it is not solved I will try inverting the antennas’ conectors to reverse the polarization. I will leave comments after the test. Greetings.
