תיאור
Stage and theatre applications often require receiving antennas for wireless microphones to be connected with the corresponding receiver over extremely long distances. (Please observe the technical specifications of your wireless transmission system with respect to maximum transmission distance). This is compounded by enormous potential for interference generated by power cables, transformers, electronic lighting control systems or mobile telephones. GA27FLEX can cope with them all. The copper wire of the inner conductor has an extra-large diameter of 2.7 mm and is enclosed in a physically foamed dielectric medium to ensure reflection-free signal transmission at ultra-low attenuation. A dual shield of Cu foil and bare braided copper provides reliable screening for the conductor from high and low-frequency electromagnetic interference. Despite the cable design featuring an extra-high-diameter inner conductor and Cu foil, this low-loss 50 ohms coaxial cable retains good flexibility.
