The Sennheiser GZL RG 58 - 0.25m (article 700158) is a short 25 cm coaxial antenna cable with a BNC connector on each end, made for connecting remote antennas and RF accessories in Sennheiser wireless microphone and in-ear monitor systems. Its typical job is linking receivers, antenna splitters, boosters and combiners inside a rack, where a short jumper keeps cabling neat and signal losses minimal. The cable uses standard 50 ohm RG 58 coax, rated by Sennheiser for frequencies up to 1,000 MHz, with an attenuation of 34.8 dB per 100 m at 400 MHz (well under 0.1 dB over this length), a capacitance of 101 pF/m and a conductor resistance of 3.54 ohms per 100 m. The cable diameter is 6.15 mm and it operates from -40 to 85 degrees C. It weighs about 83 g including packaging. For longer runs to remote antennas Sennheiser offers the same cable in 0.5 m, 1 m, 5 m and 10 m lengths, and the lower-loss GZL RG 8x for long distances. Covered by Sennheiser's two-year warranty.
