About the Avtex STH4000
From our tech experts at CEN
An Avtex mobile internet unit, giving a camper or motorhome a proper connection rather than relying on a phone on the dashboard.
Who it suits
Campers and touring caravans, where signal is less reliable than at home and a roof-mounted antenna makes a real difference over a handset indoors.
