Omnidirectional VHF high band collinear antenna, PIM rated, white, 140-174 MHz, specify 3%, 250W, N-type female, PIM <120dBc, 4.5 dBd - 4.5m

The ZCG Scalar G25 is a premium omnidirectional VHF high band collinear antenna engineered for reliable performance across the 140?174 MHz frequency range. Designed for commercial paging networks, trunked radio systems and general communication infrastructure, it delivers a strong 4.5 dBd gain with consistent 360-degree coverage for maximum field strength and signal reach. Built with low-PIM construction rated at < -120 dBc and supporting up to 250 watts of input power, the G25 ensures clean transmission quality in high-density RF environments where passive intermodulation can compromise system efficiency. Featuring a durable white radome for visual discretion and long-term weather protection, the G25 is suited for permanent installation on towers, masts or building structures. Its integrated N-type female termination provides secure connectivity to standard 50 Ohm coaxial feeder cables, allowing for straightforward integration into existing sites. With an overall length of 4.5 metres, the antenna?s extended aperture enhances elevation pattern control for improved coverage footprint over large service areas. For optimal performance, ZCG recommends mounting the G25 as high as possible on the supporting structure using UAM180L parallel clamps or UAM90L right-angle clamps. Whether deployed for emergency services, commercial dispatch, telemetry or broadcast relay applications, the G25 offers dependable wide-area communication capability with the resilience expected from mission-critical hardware.
