Why are Americans allergic to aerial cable runs? Fiber and Ethernet are low/no voltage and don't need to be buried to comply with the electrical code.
#1 - I don't really want an aerial cable running through my back yard, plus it'd have to be pretty high to give enough clearance for the septic pumping truck.
#2 - running cable between the 10th and 13th floor of buildings across the street from each other would require permission from both building owners, and maybe a permit from the city too. While a wifi link just sits in the windows on each side.
I still have fiber above ground running through my yard. ATT doesn't bury it, they just run it above ground and wait for a 3rd party contractor to come by and bury it later. Mines been above ground for 6 months now
