I thought all of the legal Repeaters were only authorised to one provider, Ie only Telstra, Optus or Vodafone. Celfi Go or Celfi Pro for Telstra.
Telcoantennas are quick to point out some facts
I have installed a Celfi Go at work that changes signal from 1 bar to full anywhere in the 20M x 20M office block.
Hopefully you have a ACMA certified one that doesn't cause more issues for you or others.
