Got a lot of WOW!s. Even from the seasoned hams! We built up the beam using the light bulb antenna, and it was very spectacular watching the light dim as we brought the reflector near, or brighten as we brought the director closer. Very informative. This one is definitely in my teaching bag. Dan,

I am planning on having my student replicate this later this semester. I would love to see a video of your experiment as well. Thanks for posting power and specs on the bulb. This is just the type of "manageable" hands-on stuff that kids (and adults) need to see. I see wayyyyy too much talk, and not near enough action in showing/demonstrating how things can be built in electronics/radio. I tend to get the "that is so easy, we could do it in no time," which translates to it will never get done. Keep up the good work at the Museum. 73, Ronny, KC5EES Austin, Texas (I forgot to put in the password characters, now WordPress thinks I'm spamming duplicates..Uggg!) This is a great video.

The reason I'm using it is that somewhere along the way, I acquired a whole box of them. I was using 10W output, and the bulb I’m using is a GE222, which is nominally a .25A, 2.25V incandescent bulb.
