A veteran installer told me my cable ties were too tight and it changed my whole approach
I used to crank those zip ties down as hard as I could until a guy with 25 years in the game pointed out I was crushing the jacket and causing signal loss. Now I leave them just snug enough to hold the bundle but with a little play. Anyone else learn a basic thing way later than you should have?
The tightness thing gets talked about but nobody mentions how overtightening makes future troubleshooting a nightmare. Had to cut a bundle once where some dipstick used industrial grade ties at maximum tension and nicked three cables in the process. Leave them a little loose and you can actually slide a new cable into the bundle later without redoing the whole mess.
