Recently my girlfriend moved house and there was no TV aerial at the property. To save money i decided to fit one myself, it was a job i wasnt looking forward to as i had no knowledge whatsoever in this field.
After trawling the internet for information on the subject i stumbled upon a site that i feel would be of benefit to everyone who is having problems with their digital service.
The cost of my install was less than £100 and included the best quality parts - i now have five televisions on Freeview (with no amplifier) and have good signal on all.
Please check out this site http://www.aerialsandtv.com/digitaltv.html
The site explains everything from choosing the right aerial for your transmitter, wiring diagrams and do's and don'ts.
