3dBi Magnetic Base (Sucker) Antenna 800-2500MHz

Description

The 3dBi Magnetic Base Antenna is a wideband omni-directional solution designed to bridge the gap between various wireless standards. With a frequency response spanning 800MHz to 2500MHz, it effectively supports major cellular bands (GSM, UMTS, LTE) and the lower WiFi/ISM 2.4GHz band. The antenna features a heavy-duty magnetic “sucker” base that provides a secure, non-invasive attachment to any flat ferrous metal surface, such as vehicle roofs, metal equipment racks, or control cabinets.

The antenna utilizes a compact whip element designed for durability and flexibility. To achieve its rated 3dBi gain and optimal signal integrity, the magnetic base leverages the metallic mounting surface as a ground plane, which stabilizes the radiation pattern and improves VSWR performance across the wide frequency spectrum. Terminated with a low-loss coaxial cable (typically RG-174) and a standard connector like SMA Male, this antenna is a “workhorse” for mobile workstations, vending machine telemetry, and improving indoor cellular reception for routers and modems.

Key Technical Advantages

• Multi-Band Versatility: A single antenna solution for 800MHz (LTE/GSM), 1800/1900MHz (PCS/DCS), 2100MHz (3G), and 2400MHz (WiFi) applications.

• Instant Magnetic Mounting: The powerful magnetic base allows for immediate positioning on any metal surface without the need for tools or permanent modifications to the mounting area.

• Compact Low-Profile Design: Its small footprint and height make it ideal for installations with limited overhead space or where a discrete profile is preferred.

• Omni-Directional Coverage: Provides 360-degree signal reception, ensuring a reliable link to cellular towers or access points from any direction.

• Optimized Ground Plane Design: Specifically engineered to work in conjunction with metal surfaces to maximize efficiency and signal propagation.
