Is anyone having success using rootenna's for long distance point to point links? Not sure if they are directional enough for our application. I'd like to use the following for some 5-10km links and not sure if they even come close to a dish or grid.

That antenna is a lot directional, but it has many side lobes.
I think it can be useful for a 10km link.

I dont know about this one, but with a small radome with 25DB gain I get 20Km with no problem.
