A few years go I made a Cantenna Dummy load. I filled it with mineral oil left over from some woodworking projects and it;s worked great for a long time. Takes a 200W or more just to get it warm…

I decided to 3D print a mount for a wattmeter on top… Had to make a base while I was at it…

 

And I made an RF power meter tap too….

Now to decide if I go Analog or TFT Display digital…. Or maybe a combo…. I do have some nice meters I got recently at a surplus store….
