Overview
The CompleTech CA390Q is a sleeve-fed quarter-wave whip antenna engineered for reliable operation within the 380-400 MHz frequency range. This antenna delivers a consistent 2 dBi gain and vertical polarization, ensuring effective signal transmission and reception for critical industrial and commercial communication systems. Constructed with a durable PE radome and a high-conductivity copper radiator, the CA390Q is built for longevity and consistent performance. Its low VSWR of less than 1.5 minimizes signal reflection and loss, contributing to overall system efficiency.
Versatility is a key feature of the CA390Q, offering a choice of BNC, N-type, SMA, or TNC male connectors for straightforward integration into existing infrastructure. This adaptability makes it suitable for a broad spectrum of applications requiring robust RF connectivity.
The antenna's design prioritizes resilience, with a construction that can withstand outdoor deployment. While specific mounting diameter and wind load specifications are not detailed in the provided catalog excerpts for this specific SKU, the general construction of CompleTech antennas suggests suitability for pole mounting in various environmental conditions. The CA390Q is an ideal choice for applications demanding dependable performance in the 380-400 MHz band, supported by CompleTech's commitment to quality RF components.
