Freeview and Australian Digital broadcasts work with less problems when decent quality antenna/rf leads are used. These are of the highest quality. They are in fact of the quality used by the professionals in the indust.
Bad reception/snowy pictures/digital breakup/pixelation on freeview or digital tv channels frequently comes down to a poor, under-performing or faulty premade/molded cheap white and nasty chinese made flylead/antenna cord. They have limited life at best and often are a problem straight out of the packet. I have seen too many times these leads under-perform on the signal meter for digital quality straight out of the packet! They really are a waste of money!
The flylead is as important as then antenna itself. These RF antenna cords are important as the quality of the cable coming down from your antenna, your wallplate, splitter and terminations when it comes to trouble free digital tv reception.
