- Less expensive to repair and upgrade
- Can be built in any terrain
- Any voltage can be placed overhead
Cons
- Susceptible to wind, ice, and snow
- More vulnerable to damage from trees and vegetation, which requires right of way trimming
- Vulnerable to blinks when animals and branches contact lines

Pros
Not vulnerable to damage from tree branches- Does not interfere with views
- No right of way (tree trimming required)
- Less susceptible to damage from vehicle collisions
- Not impacted by wind, snow, and ice
