How to transmit signal trough relay?

[RickyOri]

I'm playing a game with no extra ground stations, I set 3 relays on geostationary orbits, with 2.00 G Antennas, which should do it, but when I launch vessels (with 2.00 G antennas too), I still cannot communicate with the Space Center.

Just to be sure, the 2G antennas you have on the relays are relay antennas, not direct antennas?  For stock KSP, that is the RA-2 relay antenna that looks like a small dish.  The DTS-M1 folding antenna is 2G also, but it is a direct antenna only.

And to expand on @Cavscout74's answer; if the antenna is a relay antenna then it automatically routes signals through it. You don't have to do anything as long as it and other antenna are within range.

Antennas come in 3 forms:

 

Built in: The ones that come with drone probes, capsules and the such. VERY short range, and unrealiable beyond a low orbit. For all purposes work as direct antennas.

Direct: This are usually compact and lightweight, but can only comunicate to the Space Center or Relay Antennas. Come in many forms and transmition power.

Relay: This are the ones you are looking for. They can connect with other relays, direct antennas and Centers. Satellites must, almost always, be fitted with this type.
