SitePro 09-100S-FY GPS Antenna Tripod with 3-Position Center Staff

Purpose-Built GPS Tripod for RTK Base Stations and Static Surveying

The SitePro 09-100S-FY is a professional-grade GPS antenna tripod engineered specifically for the demands of modern surveying and machine control workflows. Unlike general-purpose instrument tripods adapted for GPS use, this tripod is built from the ground up with reinforced aluminum legs, a wide-stance footprint, and a 3-position adjustable center staff that accommodates a range of antenna mounting heights. When your base station has to stay planted through wind, uneven terrain, and long observation windows, the 09-100S-FY delivers the rigidity and stability your data depends on.

Overview and Jobsite Applications

Whether you're setting a base over a benchmark for an all-day static session, deploying an RTK base for a machine control spread, or establishing control for a boundary survey, the SitePro 09-100S-FY handles it. The bright yellow finish makes it easy to spot across an active jobsite, reducing the risk of equipment contact from heavy machinery. The wide-stance aluminum legs drive firmly into soft ground and lock without flex, keeping your antenna phase center consistent from setup to breakdown. This tripod is a reliable choice for land surveyors, construction layout crews, and GIS field teams who need a dependable antenna platform day in and day out.

Job Applications

RTK Base Station Setup: Set the 09-100S-FY over a known control point and lock in your base antenna height using the 3-position center staff. The wide-stance legs hold firm while rovers work across the site, keeping your correction stream clean and consistent throughout the day.

Static GPS Observations: For control densification, boundary surveys, or geodetic work requiring extended observation windows, this tripod's positive-lock leg clamps and stable footprint keep antenna phase center displacement to a minimum over hours-long sessions.

Machine Control Base Deployment: When you're running grading or paving operations and need a base station that won't get bumped out of position, the reinforced legs and wide footprint of the 09-100S-FY hold their ground on active construction sites with heavy equipment nearby.

GIS Data Collection: Field GIS crews benefit from the easy height adjustability and high-visibility finish, making this tripod a practical platform for sub-meter and survey-grade antenna setups in both urban and remote environments.

Frequently Asked Questions

What thread size is the center staff on the SitePro 09-100S-FY?

The center staff uses a standard 5/8-11 thread, which is compatible with the vast majority of GPS and GNSS antennas, tribrachs, and survey mounting accessories currently on the market.

Can I use this tripod for optical instruments like a total station or level?

The 09-100S-FY is designed and optimized as a GPS antenna tripod. While the 5/8-11 thread is common across survey equipment, the flat-top head and center staff configuration are intended for antenna use. For optical instruments, a dedicated instrument tripod is recommended.

How does the 3-position center staff work?

The center staff can be set at three distinct height positions without adjusting the tripod legs, giving you a quick and repeatable way to vary your antenna height for different setups or to clear obstructions. Each position locks securely to prevent movement during observation.

Is the fluorescent yellow finish just cosmetic, or does it serve a purpose on the jobsite?

The high-visibility yellow finish is a practical safety feature. On active construction sites with heavy equipment operating nearby, a brightly colored tripod is significantly easier for operators and crew to spot, reducing the risk of accidental contact with your base station setup.
