Step 10: Tophat NAROD Holder

I designed my antenna with a straight NAROD, but built in provision for trying out the several shapes and sizes of tophat NARODs. The photo shows how a 90-degree standard elbow can be drilled through to make an adjustable holder. It can be slid up and down and back and forth, then cemented in place to accommodate any tophat. A modified pipe cap confines the tophat, simulated in the photo by a short length of copper tubing.
