Product description
What you get
Two coaxial surge protectors, configured F-type female to F-type male, rated for 75 ohms and up to 1A maximum continuous current. Each unit is sized for standard F-connector coax runs and intended to be placed inline on the incoming cable feed.
Key performance and construction
These arrestors are engineered to tolerate surge discharge currents up to 100A and react extremely quickly — typical attack time is around 100 nanoseconds. When a large transient is detected the device will open the coaxial path almost instantly to prevent the surge from continuing down the line; after the event it reconnects automatically after approximately 10 seconds to resume normal signal flow. Materials and internal components are selected to provide a long operational life under normal conditions while sacrificing themselves when exposed to a damaging lightning-induced surge.
Where and how to use them
Designed for CATV, MATV, SATV and other coaxial communication systems, these protectors are installed inline at the cable entry or at other equipment access points (amplifiers, splitters, distribution amps). They are intended to shield TVs, cable boxes, satellite receivers, signal boosters and other downstream devices from surges transmitted via the coaxial cable. Correct grounding of the protector is required for maximum effectiveness; pairing an indoor entry protector with an outdoor grounded arrestor at the service point gives the best defense.
Installation and service
Installation is straightforward: screw the protector between coax segments using the F-type connections, and attach the ground according to local codes and grounding practices. The device is designed to not noticeably affect signal quality or broadband speeds when functioning normally. A two-year (24-month) warranty is included, and customer support is available for setup or troubleshooting questions.
Pros
- Fast response (≈100 ns) with 100A surge tolerance
- Simple inline F-type installation for 75Ω systems
- Auto-reconnect after event and 24-month warranty
Cons
- Sacrificial design means replacement after a major strike
- Effectiveness depends on proper external grounding
- Limited to F-type / 75Ω coax applications
VerdictThese two coaxial surge arrestors offer an affordable, easy-to-fit layer of defense for home theater and cable equipment. They respond in nanoseconds and can absorb high discharge currents, but they are sacrificial by design — expect to replace a unit after a direct hit. When properly grounded and installed at the cable entry, they reliably protect receivers, set-top boxes, modems, distribution am

Solid unit
Works well for my setup — very pleased with the product.

Interior entry protection
You still want a grounded outdoor protector at the meter, but these inline units belong at the house entrance. Very economical compared to repair bills after a strike.

Bought a second set
Good protection for the home; I liked them enough to buy another pair for other lines.

Quietly ready
Installed without trouble. I hope they never need to act, but they haven’t affected Wi‑Fi and provide peace of mind in a lightning-prone area.

Saved my router
The cable company’s spikes used to fry my modem and router. I now run two of these inline, each grounded separately. I’ve lost two protectors and a couple of modems, but my personal router has survived — worth the trade.

Did its job
Bought after a prior strike. During a storm I saw it flash and take the hit, and my mesh router lived. Definitely worthwhile.

Plug-and-protect
Straightforward add-on to the cable feed. Durability remains to be seen, but it’s a low-cost safeguard.

Simple setup
Easy to fit. Fingers crossed they shield my equipment from surges — only time will tell.
