SECO 2133-03 Radio Antenna Bracket

Overview

The SECO Radio Antenna Bracket is a convenient mounting solution for attaching external radio antennas to GNSS rover poles and survey poles. Designed for professional RTK surveying, the bracket securely mounts to poles ranging from 1 to 1.25 inches (25.4–31.8 mm) in outside diameter, allowing operators to position an external radio antenna above the receiver for improved radio communication and reduced cable clutter.

The open clamp design makes installation quick and tool-free, while the removable 5/8"-11 brass captive stud provides the flexibility to mount compatible radio antennas directly to the bracket or use additional adapters. An included non-slip Velcro® cable strap helps secure the radio cable to the pole, creating a cleaner, more organized field setup.

Fast, Secure Pole Installation

The open clamp attachment allows the bracket to be installed or removed in seconds without disassembling the survey pole. Once mounted, it provides a stable platform for positioning an external radio antenna while keeping the antenna clear of the receiver and operator.

This design helps simplify equipment setup and improves efficiency when moving between jobsites or changing field configurations.

Flexible Antenna Mounting

The included 5/8"-11 brass captive stud can be easily removed when needed, allowing compatible radio antennas to attach directly to the mounting bar. This flexibility accommodates a variety of antenna mounting styles and radio configurations used in modern GNSS surveying.

For antennas that use a 1-1/8"-18 thread, the bracket is compatible with the:

• SECO 2133-00 Radio Antenna Adapter (sold separately)

The 2133-00 adapts 1-1/8"-18 radio antennas to a standard 5/8"-11 threaded mount, expanding compatibility with many professional radio antenna systems.

Organized Cable Management

To help prevent cable snags and improve overall field organization, the bracket includes a non-slip Velcro® cable strap. This keeps the radio cable secured to the survey pole, reducing movement during transport and data collection while protecting the cable from unnecessary wear.
