DEHN DGA FF5 TV scaricatore di sovratensione coassiale per impianti antenna e satellite 909706

The DEHN DGA FF5 TV is a coaxial surge arrester engineered specifically for antenna, satellite, and multimedia coaxial systems. Unlike generic surge protectors, it combines a gas discharge tube and varistor to provide hybrid protection for both core-shield and shield-ground paths, ensuring reliable safeguarding of sensitive receivers and distribution equipment.

Highlights

• Hybrid protection technology (gas discharge tube + varistor) for robust transient suppression
• Wide frequency range up to 2400 MHz, suitable for SAT and terrestrial TV signals
• Low insertion loss (≤ 0.5 dB) and high return loss (≥ 18 dB) maintain signal integrity
• Nickel-plated brass housing for durability and corrosion resistance
• Inline F-connector design (female to male) for easy integration into existing coaxial runs

In daily use

Installed directly in the coaxial line between the antenna and the distribution amplifier or receiver, the DGA FF5 TV diverts surge currents to ground without interrupting the signal. Its compact inline form factor and standard F-connectors make it a straightforward retrofit for residential and commercial installations. With a nominal discharge current of 2.5 kA and a maximum of 5 kA, it handles typical lightning-induced surges while maintaining a voltage protection level of ≤ 600 V.
