Hello, i would like to ask what 4g Directional antenna i need to buy? im confused as all these wifi/wlan, ect antennas come up and i basically know nothing about antennas and networking.
my budget is 150$ or 110€ and i would like to be able catch 4g internet from town ~18 km away. At the moment i have fairly stable 3g, but the speed doesn't suit me. So if someone who knows something about 4g and antennas could give me a store link which sells what i need and CAN ship to Latvia (north europe) i would be happy. im stuck as i have no idea what do i need.
the terrain to the city is relatively flat, but dense forest between.
-needless to say that it has to be all year round weatherproof, rooftop antenna.

Wouldn't it be nice if things were that simple. 4g means nothing really and even you said LTE it still does not help with problem. What is most important to know is frequencies you provider uses in your area. It is not even as simple as figuring out just the provider because many have licensed different frequencies in different parts of the country....and sometimes even worse in the same city.
So once you find the frequency you can just look for antenna that operate on that frequency.
I am hoping the 18km is a typo, you will never get a solution than can go that far. You would need fairly high tower on your end ....it could be as much as 35 meters if the provider is using 700mhz radio bands.
The other major problem is you would have to have a way to connect a antenna to the device. Many devices do not have a antenna connector mostly because you can easily violate local laws regarding transmit power.
Likely the only way you are going to get this accomplished is to buy a outdoor radio/antenna combination and run ethernet inside. The cost of good quality microwave cable between the device and the antenna is outrageous.
Still if it really is 18km the answer is it can not be done.

it might be more than 18 km and what about other long range antennas? 18 km seems not big but medium distance for long range internet. aswell i have no idea how i could figure out the frequencie of signal, any indepth help what i could do?
aswell my "tower" would be ~12 meter high maybye a bit more, and it is realy impossible to intercept 4g from nearest city?
btw in my attic, my modem intercepts weak 4g (600kb/s download speed instead of 200kb/s with 3g, maybye a random tower nearby?)

If you can get 4g signal from your attic it is much closer tower. Likely less than even 1km.
The tower size is based on a function of physics called fresnel. It tends to be a very complex topic but when you talk the distances you are you need to worry about the curve of the earth blocking your signals. In addition the ground will absorb signal so you need to stay above it but since the signals constantly spread the distance increases. The math is fairly complex but there are many calculators on the net.
Your first problem is still getting the frequencies. It is a matter of either asking the company or digging though government data. The government of any country likely sold them the rights and there are records of this.
Once you have this you can go shopping for antenna. Still even if we assume you can get the close by signal you can detect you still have the problem of how do you connect the antenna to the modem especially if it is does not have a antenna connector and how you solve the problem of the antenna being on the roof and the modem needing to be in the house. You either need a different modem or expensive antenna cable. Every foot of antenna cable drops your signal, at some point it will drop more than the antenna you buy.

i have Huawei E5172 router/modem, it has an antenna port in the back. aswell my house has 1 floor and attic and im placing my modem at the celling right beneath where i will put the antenna on roof, so maybye 4-5 meters of cable. what else should i look except frequencies?
btw there is a tower less than 1km away (600m) but it is suposedly a 3g tower as on the 4g internet map that my internet provider has im not in the area of 4g. anyway is it possible to improve my internet signal from 200kb/s download to atleast 1mb/s ? i recently moved in county and the internet is too slow for daily use.
Edit:
its 1800 Mhz
how should i proceed?

This is a sample of the largest 1800mhz antenna I could possibly find. It is 24db of gain. Your problem is finding a antenna that has the largest gain you can possibly find from someplace you can actually order it from. There are antenna that cover large range of frequencies but as long as it includes the 1800mhz it will work. You want a directional antenna either a parabolic like this one or a yaggi
So once you get the antenna now you have to get the cable. The vast majority of these antenna use N type of connector but you need to check the antenna to be sure. It is physically a big connector. Your router from what I can tell uses SMA. Look very closely at the connector and pictures on the internet to be 100% sure. It is more common to need RP-SMA. Look at the photo you will be able to tell what type of connector will connect to your router.
Then last you need the microwave cable. Most the stuff you would be looking at will be called stuff like LMR400 or lmr600 etc. The larger the number the less signal loss you get but the higher the price. You do not want to buy much extra cable since every extra foot drops your signal.
You will likely have to have to order a custom cable with the type of cable you want with the connect ends on the cable to match your antenna and the router. It takes high skill to put the ends on the cable without causing more signal loss so it is well worth paying someone to build the cable rather than you try to solder them yourself.

i did a fast search and found this. would that suit my needs as i can recieve low 4g conncetion in my attic? i guess i cant aim for the 18km city but atleast i can triple my speeds if not more with the nearby tower. thank you for your time.

Not sure what happened and now the photo won't come up on the site I was going to link.
You are correct the long ones are yaggi and the dish one are parabolic. There are some strange combination ones that have parts of both.
It really doesn't matter a lot. The main difference is the shape of the radio beam they put out. In your case it likely makes no difference since you have no control over the other end. Pretty much all that matters is the DB gain not the shape of the antenna. As long as the manufacture of the antenna is reputable the numbers they quote will be valid. Just stay away from something that is way out of line price wise with every other device.
