Most likely,

I made mine out of brass strip with a piece of 4mm brass tubing, angled in the correct position.
I made a cardboard template first.

The pick-up can also be a simple bent brass tube like the one in the picture, it all depends on how far it has to extend from the transom without flexing under the pressure from the spray.
My appologies for the poor quality of some pics, it's hard to see the pick-up in some, but the pics were not shot with a pick-up in mind...
Hope you get the idea.
