Belden Brilliance® 'Low Loss' 7731A Precision High Definition TV Video Cable As of October 10th 2011, Belden have increased the UK pricing for the Brilliance® range of SDI video cables. We have therefore had to pass this on to you, our customers. We would like to apologise for this, which is outside our control. There are a number of coaxial cables suitable for the delivery of digital High Definition signals. According to SMPTE 292M specifications RG 59, RG 6, RG 7 and RG 11 are suitable for HD-SDI interfaces running at 1.458 Gbs (Gigabits per second). RG 11 variants can deliver a Digital High Definition data stream over much greater distances without signal loss, compared to the thinner cable varieties. Belden's 7731A is designed for high performance and low signal loss over distances up to approximately 500 feet (150 meters).   Technical Specification Conductor 1.626mm bare copper wire Dielectric Gas-injected foam high density polyethylene Shield material trade name Duofoil® Inner screen Aluminium/polyester tape Outer screen TCW braid 95% coverage Impedance 75 Ohm Capacitance nominal 52.50 pF per metre Velocity of propagation 85% Nominal delay 3.97 ns per metre Resistance Inner conductor 8.202 Ohms/Km Outer conductor (screen) 4.922 Ohms/Km Jacket material PVC Overall diameter 10.16mm Max reel length 305 metres Weight 15.0Kg per 100m Attenuation @ 71.5 MHz 3.6 dB/100m 88.5 MHz 4.0 dB/100m 135.0 MHz 4.8 dB/100m 180.0 MHz 5.5 dB/100m 270.0 MHz 6.9 dB/100m 750.0 MHz 12.0 dB/100m 1500.0 MHz 18.0 dB/100m 2250.0 MHz 22.6 dB/100m 3000.0 MHz 26.9 dB/100m Supplied on 305 metre drums only.   Code Description      Metre: 100 500 1000 5000 7731APV 0D Belden 7731A HDTV cable Black (305M) £3.23 £2.95 £2.72 £2.52
