Antenne Radio GmbH & Co KG
Antenne Radio GmbH & Co. KG is a German limited partnership (Kommanditgesellschaft) registered in the commercial register of the Amtsgericht Stuttgart under HRA 12050. Its registered office is at Plieninger Straße 150, 70567 Stuttgart, Baden-Württemberg. The company was entered in the register on 19 May 1993, and the Handelsregister currently lists its status as active.
The company operates the private commercial radio station marketed as “Hitradio antenne 1” (also referred to as “antenne 1”), one of the largest private FM broadcasters in Baden-Württemberg. Its programming reaches most of the state and is produced from studios in Stuttgart together with regional bureaus in Heilbronn, Pforzheim and Reutlingen. The company’s principal business activity is the production and broadcasting of commercial radio programming, financed through the sale of local, regional and national advertising airtime, together with associated digital audio and online offerings marketed under the same brand.
Radio distribution in the region has, since 2015, relied in part on shared FM transmission-network infrastructure that antenne 1 operates jointly with several other Baden-Württemberg private broadcasters, replacing a network previously operated by Media Broadcast.

Shareholders of Antenne Radio GmbH & Co. KG
Antenne Radio GmbH & Co. KG is a Kommanditgesellschaft (limited partnership) with two disclosed limited partners (Kommanditisten), per commercial-register data verified as of 4 September 2026: Stuttgart Regional Hörfunk GmbH & Co. KG, holding a 65% capital interest (nominal capital share of €1,105,000), and Radio RT 4 Programm- und Lizenzgesellschaft – Regionaler Hörfunk – GmbH & Co. OHG, holding a 35% capital interest (nominal capital share of €595,000). Both interests are direct holdings recorded as ordinary capital shares (Kommanditeinlagen) rather than listed equity. The company’s personally liable general partner (Komplementärin), which under German partnership practice typically holds no capital share in the KG, is Antenne Radio-Verwaltungsgesellschaft mbH, registered separately in Stuttgart under HRB 15690.
Stuttgart Regional Hörfunk GmbH & Co. KG is itself positioned within a wider group of Stuttgart-registered radio holding entities connected to Stuttgarter Presse Funk GmbH (HRB 11973), a multi-shareholder holding vehicle whose stated corporate purpose is to hold direct or indirect stakes in private radio broadcasters on behalf of regional press publishers. Further detail on this layer is provided in the group-structure section of this profile.
Ultimate beneficial ownership
No individual ultimate beneficial owner could be reliably identified for Antenne Radio GmbH & Co. KG. Its capital is held entirely through corporate limited partnerships (Stuttgart Regional Hörfunk GmbH & Co. KG and Radio RT 4 Programm- und Lizenzgesellschaft – Regionaler Hörfunk – GmbH & Co. OHG), and tracing the chain to natural-person UBOs would require ownership data on Stuttgarter Presse Funk GmbH’s roughly sixteen disclosed shareholders, which was not fully accessible in the sources reviewed.
Data availability
Germany publishes partnership capital shares in the Handelsregister, so disclosure for Antenne Radio GmbH & Co. KG is Full at the immediate (Kommanditist) level, but Partial to Not public for the further layers of the ownership chain, where complete shareholder lists were not accessible without a paid register extract.

Directors and officers of Antenne Radio GmbH & Co. KG
As a Kommanditgesellschaft, Antenne Radio GmbH & Co. KG is legally represented by its general partner, Antenne Radio-Verwaltungsgesellschaft mbH, rather than by directors appointed to the KG itself.

He succeeded Achim Voeske, who had served as Geschäftsführer since 2001 and left the company on 31 December 2023 on retirement.

Nationality was not officially disclosed in any source reviewed. The underlying appointment information reflects commercial-register and trade-press reporting current to April 2024, cross-checked against register data retrieved in September 2026.
