Looks like they intermingled parts from another antenna. There are 4, 1" ish U-bolts included that obviously aren't part of the antenna. Being stainless, I'll add them to my junkbox. It is a drag. I was going to install it tomorrow. I could get what I need from the local hardware, but I just haven't been going anywhere. I specified exactly what I needed. Just need to wait until they ship.
I have dry fitted everything together. Still deciding on measurements. I'm not going to cut anything. I might take a couple extra days and experiment with different chart lengths. For what this is and the price, I think it was a good buy. Looks like a decently made antenna. The sagging is nice. At least they aren't Cushcraft with rough edges and full of burrs.
