This may have been asked before, but how much should I be looking to pay for a new aerial to be installed? I've seen £117.50 here - http://www.dgmdigitalaerialinstallers.co.uk/ The one we currently have seems very old and has poor freeview reception. My postcode is DE22 if that helps at all. I know there is site which recommends what kind of aerial you need. Does anyone recommend a particular installer in Derby? I'm also interested in having one or two extra aerial points installed upstairs.
