Does Survey GNSS Multiband antenna (IP66) need a ground plane

I was wondering if it’s good practice to setup the GNSS Multiband antenna with a metal ground plane or is it not necessary for this antenna?

Necessary vs Desirable?
It is generally desirable to use a ground plane to block signals from below the plane of the antenna. How large that is depends usually on practicality. A car roof is ideal, something 14-16″ in diameter is about the limit of any measurable benefit, 7-8″ in diameter is about the smallest I’d suggest.

As a complement to clive’s message.   Unlike ANN-MB, the survey antenna is designed to be used without ground plane (there’s a good ground plane inside the antenna). Nevertheless when used on a car or building rooftop you will see a slight increase in performance.
