Trustworthy free-standing pull-up bar (for ring rows)?

I’m trying to figure out my options for a free-standing pull-up bar for the home that can allow me to do body weight rows with rings (progressing to pull-ups). It’s an added consideration because I’m not just going straight up and down on the bar, but I’m pulling it towards the ground with the rows.

It kind of seems like my only two options are to get an expensive, super heavy squat rack, or to DIY one and put two wooden poles deep in the grass with cement, which I’m not super keen on doing. But I’m also not sure that either of those options can support ring rows. Any thoughts or suggestions?

For reference, I got a standard one that’s like an upside down T, and I weighed down one side with sandbags so I can do the rows, but i just don’t trust it. The tall part of the bar leans towards me when I row, and I don’t think adding any more sandbags is going to do anything. I feel like it’s only a matter of time before it breaks on me.
