Since 1994 an RF driven H{sup -} volume source has been operated in the DESY source test stand. In 1995 the source was operated successfully as injector for LINAC III and DESY III. The source is planned as a Cs free low emittance replacement of the magnetron. H{sup -} sources for HERA have to run for long uninterrupted periods (300 days) with a low duty factor (0.01%) and a high reliability. New Al{sub 2}O{sub 3} ceramic antenna constructions are presented in order to improve the antenna lifetime. Recent measurements have demonstrated H{sup -} currents of up to 80mA in our uncesiated volume source. This was possible due to a negative bias of the collar, a tantalum coating on the collar inside and an optimization of collar and extraction geometry.
