Amplify signal for MIMO antenna

I have relocated to a house outside the city. There are two towers I know about, one hidden behind a hill, the other is too far away. I bought a parabolic multi-band antenna, and that produced a stable 4G connection when I point in the direction of the tower over the hill. But, it is only registering 1 'bar' signal strength and speed test result is about 2MB/s. The antenna is already as high as I can go with the currently available hardware. The antenna is MIMO. I was hoping to use an amplifier and a repeater to improve internet speed and give me better phone connectivity around the property. When I ask Mr Google for info on amplifying a signal from a MIMO antenna I get a big blank. Are there any experts who can advise me what the options are?

That's a tough one. Have you tried using a flat panel directional antenna instead of a parabolic? Since you are likely collecting signal reflection, versus a straight signal, you might be missing some signal with the very tight beamwidth of the parabolic antenna.
One like:

If you do want to use a cellular booster, you could get a system like the one linked below, and simply put your antenna on the end instead of the one supplied.

How long are your cables what type are you using??
Also can you give more information about the model number of your antenna.
See link for clues and hope

I tried a flat panel antenna and could not get any 4G signal. It did collect the 3G signal and gave me about 1 MB/s. The parabolic is at least getting me a stable 4G signal, even at low strength and produced 2MB/s.

My main question here is... Can I attach any sort of amplifier to a MIMO antenna to boost the strength of the signal. For example, could I put a multiband amplifier on the end of each cable from the antenna before it attaches to the modem?? Something like
||||||||||||||||||||||||||----------AMPLIFIER---------
OUTDOOR ANT ...........................................................................MODEM
||||||||||||||||||||||||||----------AMPLIFIER---------
or even better
||||||||||||||||||||||||||----------AMPLIFIER---------
OUTDOOR ANT............................................................................REPEATER ---------- INDOOR ANT
||||||||||||||||||||||||||----------AMPLIFIER---------
or maybe even
||||||||||||||||||||||||||----------AMPLIFIER---------REPEATER ---------- INDOOR ANT
OUTDOOR ANT
||||||||||||||||||||||||||----------AMPLIFIER---------REPEATER ---------- INDOOR ANT
I don't know if any of this is possible, or even if the items I am suggesting exist. I am hoping something like the first one would give me faster internet speeds. The second and third might give me faster internet speed and mobile connection for phones within the house.

I've not spent much time with signal amplifiers. Hopefully someone with experience will jump it.
I would think you could put an amp on the parabolic and feed the signal via an indoor antenna. I'm not too sure about direct to modem connection.

As with everything on the Internet trust but verify.

Short answer is yes you can but it may not help. It will make the signal louder. But it will also make the noise louder. The only way to know if it is a net positive it’s terms of performance is to try.
Be sure to get one specifically made for inline data use (ie don’t direct wire a booster meant to rebroadcast cellular signal with an indoor antenna).
