Distance is not an issue, however I live in the Appalachian Mountains and often times run into interference from trees'/mountain tops. Yeah I could probably drive to the closest mountain top and take off from there but I like flying from home. Hell 5 mile radius 360 degree is pretty dang good but i'm looking for an extra edge. Signal that will penetrate lightly dense tree cover and things like that. ideally I want to take off from the valley I am in fly over the mountain and DOWN into the next valley and be able to land (never happen but sounds cool as ****)
