Further to my last post I've attached a 50dbi powered internal aerial. I can get all Freeview channels with 100% clarity when antenna is vertical but not HD on ch21 474.2 MHz . Rotate it to horizontal and I get all HD channels but not all Freeview channels. Did the polarisation change in early December? When I lost the signals it was like someone had switched something off. Can anyone shed light on this please.
