Key Product Benefits

- Ideally suited to protect Broadband CATV subscriber’s “COSTLY” HDTV receivers, DVRs, cable modems, home networking components and interfaces from potentially damaging surges.
- Will reduce “out of warranty” repair expense caused by surge lightning damage. Reduce service outages by protecting against induced high-voltage surges that may appear on the center conductor of a coaxial drop cable.
- Unique In-Line® design is impedance matched to 75 ohms and is virtually transparent to all analog or digital bi-directional signals transmitted from DC to 1.0 GHz.
- tii’s patented proprietary coaxial gas tube surge protector is equipped with an integral failshort mechanism for a powercross condition which shunts both the coaxial cable’s center conductor and sheath for a common path to ground. The DC breakdown voltage of the protector provides superior protection against transient surges, yet is compatible with network powered applications.
- The protection element is designed to reset after each over voltage event.
- Metallic housing of the tii In-Line® Coaxial Lightning Surge Protector provides necessary EMI shielding.
- When properly connected the protector is environmentally sealed (15 psi) to prevent ingress of moisture and humidity encountered in broadband pedestals, vaults, NIDs and stand alone applications.
- Full 360° “F” port connectors provide superior RF performance and tighter connections.

Industry Standards
- Listed to UL 497 & CSA Certified.
- Meets and exceeds Telcordia GR2908-CORE.
- Complies with 1999 National Electric Code.

TII makes the only UL listed protectors I've ever found. When I worked for the phone company, we installed TII's telephone protectors. The ONLY time I ever saw surge damage was when they weren't grounded properly.
it seems well made

Feels rugged and looks corrosion resistant. I dont detect any insertion loss. The screw lug easily accepts 8AWG stranded wire. I dont think the antenna has been hit by lightening yet so theres not much to say. If I see a hit and the TV still works Ill update this review.
