I installed directv for a while and I was able to get signal from 95 percent of my installs in Buffalo and upstate New York even with trees around.
The reason I mention New York is as you travel south it gets easier to obtain a signal since the dish needs to be aimed higher to accommodate the position of the satellite in orbit.
By the time you get to Texas the things are practically aimed straight up making trees a non issue unless it's under a canopy.
All I ever really needed was a handheld tool to find the azimuth of the satellite and then check the elevation for clearance. I needed 35 degrees for elevation to hit three different satellites on the directv dish. I did a quick search on starlink and it says it needs 40 degrees for users but didn't state where on earth that applies.
Point being, you can snipe reception through gaps in trees if it really becomes an issue.
