Thank you for all your replies. My plan is to make sure I know what I have and what I need. A photo of the top of the mizzen is attached, this shows what is labelled as 1. Emergency VHF on top,
2. DSC, curved and horizontal, 3. TV,
From the Forum sounds like the Curved horizontal aerial labelled DSC is not required or possibly wrongly labelled. The Emergency could be replaced with one that came with the AIS, which could be used for the radio if needed.
Have I missed anything? Thanks again.
