Connected to my Raymarine
backbone among other things is a Raymarine RS150
. Its mounted up top of my radar arch
on a 5m spur cable, which is the long spur cable.
It had worked flawlessly for about a 1 year, then last weekend it sudddenly dropped offline as a source of data for the chart plotter. The LED on the GPS
was flashing red indicating it had power (which is also supplied through the spur cable).
I reseated all the cables
and even tried a different plug
into the backbone - no joy.
Roll forward to this weekend and it fired up just fine. Raymarine
say the failure rate on the RS150 is very low and to look at the cable, which makes sense.
I have just noticed that I don't have those clamp on RF chokes on the spur cable. I will put two on, one at either end - would this be typically how a RF interference
problem would present (intermittent data loss but still have power) and is the RF choke what would fix it?
The second RF choke will be exposed to the weather
- how do you waterproof them?
