5 GHz Bridges absolutely need to have a clear line of site.
With 2.4 GHz Bridges a clear line of site is still the absolute best, but it is a little more forgiving with line of site issues.
You may be able to get away with a few trees in the way, or a few power lines. 2.4 GHz may have more issues with outside interference from other devices that operate on the 2.4 GHz Frequency (Cordless Phone, Wireless Routers, Baby Monitors, etc.).
5 GHz operates on an unlicensed frequency spectrum and will be less likely to have problems with interference with other devices. Both 2.4 GHz and 5 GHz operate in the unlicensed frequency spectrum.
2.4GHz has more interference because there are a lot more devices out there that run on 2.4GHz, this makes the air waves more congested.
