Light, a mirror and magnifying glass; driven element, reflector and director element(s). Genius. Magnificent explanation from one of, if not the best communicator in amateur radio. Congratulations Jim - you’ve done it again!
Again, a very nice visual demonstration of how one of these antennas work. Well done! Love the lightbulb/magnifying glass illustration. Very well done.
Two phased 20m antennas, that sounds amazing. Thank you for presenting this information. You made it easy to visualize that which is normally printed in a book.
Funny this big lego mockup. Or are sometimes really these big tubes used for the actual antenna? Maybe for another video, whats the use of two yaggis? I just guess, double power, maybe more directionality for a twin setup?? by having phase control it also works out somewhat when they are rotated??
Thanks Jim for a simple, easy to remember the workings of a yagi. Also, thanks for the Hexbeam comparison. I have the K4KIO and I do see a marked difference from the Cushcraft Tribander I use to have. Love my Hex! Now, only if you could give a simple explanation as to what makes a Triband yagi, a 3 band antenna, if we stay with the fact that the driven dipole element is cut a specific frequency. 73 Bob ka9bhd
Hi Jim, Nice concise video. Great job. I have the T2X rotator and seven element triband yagi that uses full length dipoles as the radiators on a 24 ft. boom. 73 WB3BJU
Perhaps it is like two magnifying glasses. You can focus them to a really narrow point by positioning. Keep in mind, a boom can be too long and the gain & f/bsuffers. 73, JIm
I always enjoy your videos, great information for helping out all other operators! That's why I do it and that's what this hobby is all about.. Ke0mje 73
Interesting video Jim and thanks for the breakdown of the simple simplicity of the famed Yagi. May its use in amateur radio continue to be demystified. I'm very curious, could you please explain, how you go about using 2 separate in concert with each other. Please go into detail about the wiring. Does each Yagi have its own individual run back to your radio room? Thanks Jim for what you do, de KE0RfZ
A helical element is not going to be as efficient. How much less, I don't know. I bought two long coils and will try something soon. My seat of the pants guess is that if the helical element is, let's say, 50% shorter that the efficiency is much better than 50%....maybe 75% depending on construction, Q, placement, etc. 73, Jim
Nice explanation, did not know much about the Yagi. Living in a condo looks like i'll have to stick with my G5RV and End Fed. Great informative video! Thanks Jim!

This was a brilliantly simple explanation of the yagis, hex, and other directional antennas. ❤
Best analogy for how a Yagi works I have heard

Hey Jim, Thanks for this video, and others I've watched. Self studying for my Technician License, and your videos are appreciated.
Another great and informative video Jim, thanks for uploading it. 73 DE W4IPC
Great video as always. I was tuning around today and heard you in a Qso on 14.220. 73 KC3KOP

Great video I always look forward to your material. Jim! Keep'm coming! 73's. David, KM5AT
Enjoyed the video, Jim, well done.

Perfect video Jim. Can you explain why boom length is so important. Longer the boom the better....hope we talk soon. KB8YBG JIM

Jim can u explain how my mosely 3 element works on 3 bands...its a little confusing...tnx AGAIN...KB8YBG Jim
Hi Jim you look like you're getting younger! HI, Also large Resident radiant coils on a Yaggie helps With signal strength.

Great job jim
Love your videos hope you are still doing good 73s kn4kbn
Great video! I’m fascinated by the brackets on your mock-up beam. What antenna are they from?
From my pile of aluminum antenna parts in the yard. Thanks Dick for watching. 73, Jim
Thankyou Sir
Any scientific comparison you can make with helical antennas with Yagi ?
A helical element is not going to be as efficient. How much less, I don't know. I bought two long coils and will try something soon. My seat of the pants guess is that if the helical element is, let's say, 50% shorter that the efficiency is much better than 50%....maybe 75% depending on construction, Q, placement, etc. 73, Jim
