NKP-TEL-4C-T
Antennas are susceptible to direct lightning strikes and induced surges from nearby strikes. Even if an external lightning protection system exists is present the discharge secondary effects can still affect TV or RF signals. For this the revolutionary NKP-TEL-4C-T Coaxial Surge Protective Devices should be used. It can protect coaxial signal against transients of cable TV and antenna, by taking the induced as well as conducted surges to the ground. The systematic use of MOV, gas discharge tube and fast clamping diodes, provides a large discharge current capacity and low attenuation, ensuring reliable communication.
NKP-TEL-4C-T sports various designs and connection methods available for every application, such as N, BNC, F, L16, SL16, etc. connectors are optional.

*Installation Notes
- Must disconnect power before installation, no hot-line operation is allowed, and better to under the guidance of professional electrician.
- For best performance, mount protector in serial with the equipment it is protecting as close as possible, and better to install one protector at each end of the data line.
- The ground wire on the product (if included) must be attached directly to the metal chassis of the equipment to be protected. The length of the grounded wire is not to exceed 11 inches.
- No special maintenance is needed, however regular inspection is needed, especially during storm seasons.
