A few thoughts on installs that you might want to address.
Never extend past 150ft without power injection (stock SL router cannot handle it and neither can the braided cable)
Starlink is not standard POE pinout.
Gen 1 round and gen 2 squareish have different power requirements.
Gen 1 needs close to 180w peak 56v. I have only run gen 1 stock power injector by putting 110 at the bottom in an enclosure and extended 150ft up with cat6 23awg. splicing into the dishy plug a few feet from the dishy.
Gen 2 is more common and lower power. listed the power brick below.
Run one cable spliced from SL router to the tree data port with a plastic jack. Run one from the power brick to the injector +- input. half the pairs for positive (center cable), half for negative (outer wire on reolinks bricks snipped and stripped plug wire). (crimp these well with a proper size inline wire splice) (shield your crimps with electrical tape)
You can use the stock 150 cable for the vertical rather than splicing in cat that will be up above but either can work just be sure to keep your foil shielding and drip wire linked at the splice and touching and also grounded with metal jack on the injector end. google how to ground a network jack if you dont know.
Dont ground loop.
The SL router is grounded so you should make sure the cable coming from the house to the base of the tree or tower is not grounded at the end with the dishy or you are creating a ground loop that could damage your dishy or router even with a near strike. so use grounded network jacks on the tree side and ground your injector at the base of the tree and use ungrounded on the house to injector side.
3d printed pipe adapters make for a cleaner mount or you can just wipe out the Trex tape.
use cat6 shielded outdoor direct burial cable.

Use basic electrical tape for your spliced pairs and a few sealing half lapped then Scotch Mastic Tape 2228 half lapped past your previous then followed by another half lap of basic electrical. Take your time on these and make your laps clean.
You can finger twist tight your splices if you are good at it or use these.

Make a loop and tape it flat to take any tension off your splices.
Here is the power brick

Here are the injection port options. Both have been difficult to find reliably in stock.
https://www.mccowntech.com/product/outdoor-gige-ethernet-poe-injector/ (needs proper pinout) 1 in upper left, one upper right, one lower left, one lower right. the 4 prongs in the middle leave empty.
Put the brick line positive in the left power input and the negative in the right. (dont clamp jacket and dont leave copper sticking out, be flush)

If the cable is in a place a dog or landscaper is likely to cut it, use electrical conduit up to the poe port. a J in the ground and some straight to the box with a few wall clamps.
