LP140

The CompleTech LP140 Quarter Wave Lightning Protector (SKU: LP140) is a precision-engineered RF surge protection device designed for critical applications in the 126-154 MHz frequency range. This quarter-wave design provides superior transient suppression for lightning strikes and electrical surges, safeguarding sensitive RF equipment such as transmitters, receivers, and antennas in broadcast, radar, and telecommunications systems. The LP140 features a VSWR of less than 1.2 across its operating band, ensuring minimal signal reflection and maximum power transfer to connected equipment. This low VSWR is essential for maintaining signal integrity in high-stakes applications where even minor degradation can compromise system performance. Available with N-female/N-male or TNC-female/TNC-male connector configurations, the LP140 offers versatile compatibility with standard RF infrastructure components. The M8 mounting interface enables secure installation in harsh environments, including outdoor enclosures, antenna towers, and industrial control rooms. Key applications include broadcast transmission systems, radar installations, wireless communication networks, and any RF infrastructure where transient voltage protection is critical. The LP140’s quarter-wave design inherently provides broadband protection while maintaining low insertion loss, making it an ideal choice for mission-critical installations where reliability cannot be compromised.
