I´ve looked at How to Set Up an IR Remote and Receiver on an Arduino - Circuit Basics and I have concluded that the reciever doesnt have enough range for the purpouse I intend to use it for. I want at least 50m range. Could I add an antenna to increase the range or should I bet my money on other hardware?
Could someone in that case give me a link to something you recommend?
Thanks 
How does one add an antenna to an ir receiver?

What do you mean by "the receiver", you need to specify an actual transmitter and receiver pair. If you want to increased range then you need a more powerful transmitter and/or a more sensitive receiver. Given that you are wanting a range of 50m I guess this is for outdoor use? There is going to be lots of background "noise" which modulation may help you get round. A strong, i.e. "bright", transmitter may be your best bet. Also don't forget that IR is essentially for point to point communications, it cannot get round obstacles
The typical method to increase the range of an IR system is to use more IR on the transmitter side.
Here is an example from a micro radio control plane with an IR receiver. The transmitter has multiple IR emitters.
Could you use a length of optical fibre?
Say, about 50 metres of it?
As vinceherman says, use more power in the transmitter. Creating an IR reflecting reflector at the transmitter focusing the beam could be a possible way to go. What is the specified range for Your IR set?
