Diamond MGC50 Through-Window Flat Coax CableThe Diamond MGC50 is a flat through-window coaxial cable that routes coax into your vehicle or building through a window gap — no drilling or permanent modification required. Despite its slim profile, it covers DC to 1500MHz with low insertion loss and tiered power ratings across HF, VHF, UHF, and microwave, making it a practical solution for amateur radio, scanner, and communication installations where a clean, discreet cable run is needed.Key Features Flat coax design routes through window gaps — no drilling required Covers DC to 1500MHz — HF through microwave Low insertion loss: 0.3dB at 144MHz, 0.6dB at 440MHz, 1.6dB at 1200MHz SO-239 connectors at both ends ~50cm (19.6") length — suitable for most vehicle and window installations Ideal for vehicles, apartments, and temporary or portable setups Technical Specifications Frequency Range: DC–1500MHz Connectors: SO-239 (both ends) Length: ~50cm (19.6") Impedance: 50Ω Max Power: 150W PEP HF / 50W CW / 40W FM VHF / 30W FM UHF / 10W FM (900MHz–1.3GHz) VSWR:
