Triax TV 4+1 proteção contra sobretensão para cabos coaxiais e ligação à terra 389056

Unlike basic power strips that only guard electrical outlets, the Triax TV 4+1 focuses on the often-overlooked vulnerability of coaxial signal paths. It shields up to four independent F-type lines—terrestrial TV, satellite IF, or a mix—plus a dedicated ground connection, making it a specialized defender for your entire reception setup.

Highlights

• Protects 4 coaxial lines (F-type female) and 1 ground terminal
• Wide frequency range 5–2400 MHz, ideal for TV and SAT IF
• High surge capacity: 20 kA nominal discharge current per line
• Low insertion loss (< 0.5 dB) preserves signal quality
• Die-cast metal housing with wall-mount option

In daily use

Install the unit close to your antenna or satellite dish entry point. Connect the incoming coaxial cables to the F-type ports, and secure the ground wire to the screw terminal (up to 16 mm²). During a lightning strike or surge event, the protector diverts excess energy to ground, preventing damage to receivers, TVs, and other connected equipment. Its robust metal enclosure withstands harsh environments, and the wide operating temperature range (-40 to +85 °C) ensures reliable performance in attics, basements, or outdoor enclosures.
