SMA male to female RF surge protector


SMA male to female RF Lightning arrester - up to 3GHz

-SMA Female to SMA Male connectors

- Protect your antenna and device from dangerous electrical surges.

Telsto series of DC pass RF lightning and surge protection products with an extended frequency operating band from DC to 3000MHz. Male to Female arresters are designed for installation in-line between an antenna and feeder cable. By installing at the tower-top position, this arrester helps protect not only the end user equipment, but the cabling itself.

More info

RF surge protector (also known as lightning arrester) CBT.763.249 from is manufactured to precise radio frequency component standards for protection from electrical surges. This RF surge protector component in a coaxial in-line design is manufactured with SMA connectors and they are 50 Ohm.

Our surge arrestors and components feature low return loss, low insertion loss and low passive intermodulation (PIM). Have replaceable gas discharge tubes (GDT) and a ground lug terminal to provide superior grounding.
The surge protector are available with GDT of 90, 145, 230, 350, 470 ± 20% volts.

RF surge protectors / RF lightning arrestors from are commonly used on antenna installations to protect sensitive equipment and are specially designed to pass the desired frequency while suppressing lightning surges.

Radiocommunication systems which are connected to an antenna are especially exposed to lightning strikes. The maximum risk is a direct strike on the antenna pole. Equipment such as GSM/UMTS or TETRA base stations must be protected from this risk in order to ensure service continuity.

These surge arrestors are available in a wide range of types and configurations, including designs that support applications like 2G, 3G, 4G, LTE, Wifi, WiMAX, FM, AM, VHF and UHF broadcast.
