Radar Extension Cables

[dkritter]

Hello,

I currently have a Pathfinder radar system installed.

I just purchased and plan on installing a RD424HD radome on my sailboat. The HD424 came with a 10 m cable which runs from the HD424 to the base of the mast. The cable has a data connection and power/ground pigtail on the end at the base of the mast.

I purchased a E55080D extension cable to get me from the base of the mast to the back of the E125 unit at the nav station. So far makes sense.

Now the E55080D seems to be just a data cable and does not have the power/ground pigtail.

My question is, do I also have to run a seperate power line from the base of the mast to the breaker at the nav station to supply power to the radome?

Thanks
