I have three aerials on my recently purchased trawler, along with a number of other electronic receivers/transmitters. I'm still working my way through the boat and have a few lingering questions:
- I understand a separate aerial is required for each VHF, which accounts for 2 aerials, so I assume the 3rd is for use as an FM radio antenna. There are 2 un-used coax cables in the boat (2nd photo) - one of those is definitely for the TV receiver (which we don't use). Does anyone know if the 2nd might be for the extra aerial? Do aerials typically have a coax connection? Would it be common practice to get an adapter from coax to stereo antenna?
- How would I test these connections to see which does what? It's a bit difficult to physically trace these - I could test by plugging into the antenna port for my stereo I suppose. Any other suggestions?
- There are 2 very small receivers on my radar arch - see photo. One at the very top and one lower. I believe at least one of these would be for the chart plotter GPS receiver, any ideas what the other one is for? AIS? Or possibly for the 2nd chart plotter, although that one is slaved to the first.
Thanks!
