£59 cost for a diagnostic check and £240 to install a signal booster. The work undertaken did not work and there is still a weak/poor picture on the Freeview Television. I have asked to return the signal booster as it is not fit for purpose and Aerial Force want to charge £69 to disconnect the Box and £69 to collect it, so £138 to collect equipment that is not doing what it is meant to. I am currently in the process of saying I can disconnect and return the box myself by Royal Mail Secure delivery and save £138. Please be aware of this company which has high costs. A google search will find a Signal Booster for £20 so be very very careful before using this company.
