Rigid line is the collective name for those components needed to connect transmitters to combiners. Our extensive rigid line range is produced using only the highest quality materials, to ensure long-term and reliable performance for both indoor and outdoor use. Low-loss copper alloys ensure high conductivity. Tubes are connected with silver-plated copper sleeves and tightened with hose clamps, while inner conductors are connected using silver-plated brass bullets. Available in a variety of sizes for VHF/UHF television and medium to high power FM applications. Our rigid line systems have minimum VSWR.
