Proxicast 5-in-1 Low-Profile 2x2 MIMO Vehicle Antenna - Durable

In this review the Proxicast 5-in-1 Pro-Grade low-profile vehicle antenna is examined for fleet, telematics and mobile broadband use. The bottom line: it is for users who need combined cellular, Wi-Fi and GPS reception in a single vandal-resistant dome and want straightforward compatibility with multi-radio routers. The single biggest reason to buy is the integrated 2x2 MIMO support for 4G/5G and dual-band Wi-Fi inside a compact IP67-rated housing that simplifies installations on buses, trucks and service vehicles.

Key Features

• 5-in-1 Integration: Combines two 4G/5G antennas, two Wi-Fi antennas and one GPS/GNSS antenna in a single enclosure to reduce roof clutter and wiring complexity.
• 2x2 MIMO for Cellular: Provides 2x2 MIMO capability for 4G and 5G bands, improving throughput and reliability on networks including FirstNet and CBRS.
• Dual-Band Wi-Fi: Supports dual band Wi-Fi including 2.4, 5.8 and extended bands around 6/7 GHz so it can serve both client and backhaul roles.
• Low Profile Rugged Design: A 3 in high IP67-rated dome that is vandal resistant and suited to transportation, kiosks and remote monitoring installations.
• Wide Router Compatibility: Works with multi-radio routers and modems from Cradlepoint, Digi, Peplink, Sierra Wireless and similar devices for easy integration.
• Long Coax Leads: Supplied with extra long coax leads to reach equipment in large vehicles like buses, RVs and mobile command trailers.

Who It's For

The antenna is aimed at fleet managers, telematics integrators and installers who need a compact, weatherproof antenna that supports simultaneous cellular, Wi-Fi and GPS on a single mount. It is particularly useful for large vehicles where long internal cable runs and multiple radio inputs are required.

Those who should look elsewhere include users who need a permanent rooftop mast with taller clearance for directional antennas, or hobbyists who require antenna models tuned to a single narrow band-this product favors multi-band, multi-radio convenience over single-band tuning precision.

Pros & Cons

Pros

• Combines multiple radios into one low-profile dome, reducing installation time and roof clutter.
• Supports 2x2 MIMO on 4G/5G and dual-band Wi-Fi to improve throughput and connection stability.
• Rugged IP67 enclosure suited to transportation and remote monitoring environments.
• Long coax leads make it practical for large vehicles and varied mounting locations.

Cons

• Performance can vary by environment; some customers report mixed connectivity results in challenging RF conditions.
• Integrated design means you cannot separately position cellular and Wi-Fi antennas for optimal isolation if that is required.
