The power for directional radio was quite small in comparison to the Uetliberg TV-tower: 10W at the maximum for a connection from Felsenegg to Chasseral of about 110 kilometres (68 mi).

[5] As the old tower neared the end of its lifespan, it was assessed as both in need of refurbishment, as well as oversized for modern usage.

[6] However, the old tower was put under cantonal cultural heritage protection in 2017, preventing major changes to the site.

[1] Contrary to its predecessor, it features no interior, since it does not need to be staffed and since all technical installations were shrunk to fit underground.

[1][8] The new tower acts as a relay transmitter for frequencies of the types VHF, DAB+, microwave, airband as well as LPWA for the Internet of things and telehousing.
