At the moment I am using 2 aerials I bought from park my auto that are connected to my freeview box,dam good reception, and the cables come through next to the side pillar next to my door, I would like to remove the radio one on the roof, and fit a combined one, does anyone know if these are available, or is there anything on the market that I could utilize the rear screen demist and turn the rear screen into an Aeriel

TRY THIS

That will throw fault codes galore on the columbus.

You'll need an aerial with an amplified base, the columbus puts 12V down the antennas core and ignoring this could cause damage to the columbus along with the fault codes. The 12V aerial supply cannot be turned off and putting 12V into a standard aerial could have unpredictable results.

Thanks for that Mannyo, I had a look at the one in the link but it does not have the connectors required to run the TV aerial cable from the base of it to the freeview box

Have you seen one somewhere that will work??
