Products: CableFree Surge Arrester for RF 0-6GHz range
The CableFree Surge Arrester for RF cables (0-6GHz, including IF cables) uses high-quality components throughout the design, with stable performance, from over current to over-voltage all have made comprehensive protection. The internal structure includes surge protection for RF cable surges which can prevent your systems and equipment from surge damage caused by electrostatic discharge or lightning strike.
Due to its superior RF performance the unit is ideal for 5GHz Radio Links (IEEE 802.11a, 802.11n, 802.11ac) and other 5.2 – 5.8 GHz ISM and UNII applications, as well as 3.5GHz 4G/5G/LTE applications. Another feature of this surge protector is that it will pass DC power voltages including up to 48V DC, ensuring that it is suitable for applications where DC is carried through the coax cable such as remote radio heads, Microwave Outdoor Units (ODUs), remote amplifiers and LNAs. One specific application is Split Mount Microwave (IDU + ODU) where the power from IDU to ODU is carried up the IF (Intermediate Frequency) cable along with the IF signals.
The CableFree Surge Arrester for 0-6GHz RF signals is typically installed at an outdoor or indoor location next to the radio equipment to protect customer network equipment.

As with all commercial surge protectors, this product is intended to prevent damage due to power surges, ESD events and indirect lightning strikes but cannot guarantee full protection in every case especially direct lightning strikes. A direct strike can contain 5 billion joules, which over 10 microseconds is equal to 500 trillion watts. Ensure you carefully earth and ground all outdoor equipment in accordance with regulations.
Wireless Excellence does not accept responsibility for damage caused by direct strikes or 3rd party installations
