I used a short length of pipe to secure the tape in the T. Beveled the edges a bit to make it easier to start.

Is this a straight enough beam element? Or should I use hose clamps. Thinking about turning it in my lathe to remove the pipe stop ridges inside to create a clear path.

		+	What fun! I took it out for my fist hunt Saturday 9/5/2015. I'm amazed at the directional capabilities of the tape measure yagi antenna. I do want to build an attenuator for it. The slight bow of the elements mentioned earlier didn't appear to be a problem. The hair pin fit inside the tube.
