cable booster

At my rec property I have cablevision TV wired into the cabin. It works perfectly for the rainy days but I tried to run a long wire (125') out to a guest trailer in the yard and have it there too. Seems like that run in too long for it to work properly.

Is there a way to boost the signal to the trailer through this long extension? Would the booster go in the trailer to pull the signal or in the cabin to push it?

Thanks.
