Sender Pfänder, Radio transmission tower in Lochau, Austria

Sender Pfänder is a broadcasting facility on the Pfänder mountain in Vorarlberg, consisting of a steel tube mast with a surrounding lattice structure. The installation distributes radio and television signals across the border region between Austria and Germany.

The steel tube mast was erected between 1955 and 1957 and stands at 1049.5 m above sea level, surrounded by a 43.5 m lattice structure with three platforms for directional radio antennas. The old GfK cylinder in use since 1968 was replaced on 14 November 2012 by a new one of the same 10 m height, allowing an additional DVB-T multiplex and a DVB-T2 multiplex. On 28 May 2019 the national DAB+ multiplex on channel 5B and the German federal multiplex on 5C went on air, bringing over 20 new digital radio programmes to the Bodensee region.

The transmitter's internal name is BREGENZ1. Its overspill carries Austrian, German and Swiss radio and TV programmes far into Baden-Württemberg, including Lindau, Friedrichshafen, Ravensburg and Konstanz, and even into high parts of the Black Forest. Swiss broadcasters also use the site to reach the Lake Constance shore and the Rhine valley.

The mast stands at 1049.5 m above sea level on the Pfänder ridge, with the lattice section's three directional-radio platforms at 21.6, 29.6 and 36.3 m. Because reception needs a line of sight to the relay stations at Feldkirch, the Ulmer Hütte via the passive Valluga relay and the Säntis in Switzerland, the site is best viewed from the open ridge paths near the summit.

In 2012, the tower underwent modernization with the replacement of its GFK cylinder, enabling additional DVB-T multiplexes for enhanced broadcasting capabilities.
