But the point is we dont want the equipment to update, as there is nothing new to add, but the update will pick up the wrong signals from other transmitters during the process.
On the other hand, leaving the function Off all the time means you dont automatically get actual changes to the Freeview service.
We are a bit lucky where we live, as the all the wrong channels are at the start of the tuning band, with the ones we want all at the top. So for now, I am triggering auto scans using the menu when I know there is a real change happening, and keeping the aerial cord unplugged until the progress bar is half way along the screen, then quickly plug in. But we still have to keep the auto channel scan service off otherwise the passive scan be it in the background or at night will find those channels are the begining of the tuning scale which were not there when I did the manual scan. The software would think a new service had been added.
For the future, I am considering switching the Wideband aerial for a Group C/D one, so it doesnt pick up the unwanted channels in the Group A scale, and should improve the reception of the channels we do want. I hope this will result in a smaller aerial too, as this is a very windy area and wind loading is still a concern.
For some area's a Grouped aerial is not an option, eg if the channels are spread over a very wide frequency range. In such situations I would opt for a Log period aerial, as although they are designed for all channels, they have a narrow signal acceptance angle - they should only pick up the transmitter in front, and none to the sides.
