Restrictions of the waveplan of Geneva required a minimum of radiation in direction Northeast, in order to reduce interferences of the transmitter Saint Petersburg, Russia, on the same frequency, if transmission power is 600 kilowatts at night. Therefore, in 1978 a 71-metre-high guyed steel-framework mast, which is insulated against ground, was built near the mast upper mentioned. Because a power reduction toward Northeast is not necessary with a transmission power of 100 kilowatts, this mast is now obsolete, but it is still there.
