I am going to be buying an external 3G antennae to mount on my van roof. To get the best possible speed I am choosing a directional one. The problem with this is I will need to know what direction the mast is from my van.
After much googling I found the Ofcom site this seems to be the only place that has a database of Mast locations. Its not easy to use as you have to zoom in as far as possible before clicking on the blue triangle to get the information on the mast. If it isn’t a 3G mast you have to zoom out and then zoom back in on another mast.
However it is better than nothing….
