Why is a aerial dog run cable? not just use a dog tie out cable and stake set?
First, you want something permanent, that you wouldn’t have to deal with removing every time the lawn guy comes to mow?
Secondly, you want your dog to have a lot of running room, a long thin space, not a circular space?
At last, are there many obstacles (e.g., outdoor tables and chairs, flowers or other plants.) in your yard, which make tie out stake unable to install in the ground?
