"Janine" was equipped with two transmitters. First a 10 kilowatt transmitter that had formerly belonged to Radio 270 and Capital Radio (the 1970 offshore pirate station of that name). By this time, however, the transmitter had been cannibalized for spare parts and had to be rebuilt. The second transmitter was a 1 kilowatt RCA transmitter that had been used ten years earlier by the Dutch offshore station Radio Noordzee from the REM-island. This became Radio Atlantis' primary transmitter. A new studio had to be built from scratch, and Atlantis commissioned a new antenna mast from a Dutch shipyard to replace the ship's existing T-aerial.
