Dish & indoor

Ok So My ISP totally screwed me over, they did the Installation and they stuck my router up on a tower 25M from ground, so now everytime we get bad weather my router gets fried by lightning :frowning: , So I was thinking of sticking something like a Dish on the tower with my router in the house with me, Will this work and if so what dish or antenna should I be looking at, Also Will I be able to do the installation myself?

I recently changed ISP’s who stuck on a loan router as they suspect something wrong with my MikroTik, Will I be able to reconfigure my Router with their settings myself or should they do it?

Please help, I am offline and still paying.

Thanks
