Ylijännitesuoja Televes USS4300 0–3000 MHz maadoitusliitännällä

Televes USS4300 0–3000 MHz with Ground Connection is a compact surge protector engineered for radio frequency (RF) coaxial systems. It covers the full 0–3000 MHz band to protect TV, satellite and broadband antenna feeds from transient overvoltages caused by lightning or switching events. The unit integrates a ground connection that allows safe discharge of induced surges to earth while maintaining signal integrity for connected equipment.

Advantages

The device provides broadband surge protection across a wide frequency range, ensuring compatibility with terrestrial television, satellite reception and wideband data signals. Its grounded design reduces the risk of equipment damage by diverting transients away from sensitive receivers and tuners. The compact form factor and straightforward coaxial connectors simplify inline installation in antenna distribution systems without requiring major changes to cabling.

Suitable for

• Terrestrial TV antenna installations
• Satellite LNB and dish feed protection
• Broadband and cable internet antenna feeds
• Residential and small commercial RF distribution systems

Key specifications

• Frequency range: 0–3000 MHz
• Connection type: coaxial in/out with ground terminal
• Function: overvoltage/surge protection for RF signals
• Installation position: inline on coaxial feed
• Typical applications: TV, satellite and broadband antenna feeds

How to use

Install the surge protector inline on the coaxial feed between the antenna or LNB and the receiver or distribution amplifier. Connect the coaxial input and output using the matching connectors and ensure the ground terminal is securely connected to a suitable earth point following local grounding standards. Verify continuity of the ground connection and test signal integrity after installation. Periodically inspect the unit and grounding connection for corrosion or mechanical damage.

Recommendations

Use this surge protector as part of a comprehensive lightning protection strategy: combine proper antenna grounding, surge protection at service entry points and regular inspection. Avoid installing the unit in locations exposed to standing water or extreme mechanical stress; place it where heat can dissipate and connections remain dry.
