On good gravel roads if I’m not paying attention and find myself going over 100km/h quite regularly. Depends on the county/MD. Some are better at maintains roads than others.
Yeah, I've done that on good gravel roads here in the south west USA.
Usually the noise of the road drowns out the antenna noise, so I tend to not realize it.
Back on topic, I can understand the need for a good external antenna, I know out in the sticks cell coverage is spotty. Jobs that are dangerous like that where lives can depend on getting help makes it important. I'm sure getting better data throughput is important, too.
Still not sure the butt-ugly antenna is necessary. I bet there's some marketing behind it, making it large, stand out and complex looking probably adds to sales.
I used to have a BDA in one of my old trucks. We had an area we often camped in where my cell phone would not work. Adding the good external antenna and BDA in the truck would get me acceptable service. I kind of miss it and have though about adding another one, but most of them are so cheesy looking that my pride gets in the way. Also, I'd much rather have a phone with an antenna port. The re-radiated signal inside a metal cage isn't my idea of a good approach, although I know it works well enough.
