Thoroughly enjoyed the demo. Years ago before becoming a ham radio operator, I would hear Yagi antenna operators say "they picked up the transmission off the back side." Your demo reminded me of this as I watched the meter. Very informative. Thank you!!
Nice example. I had seen an older example where they lite a small bulb with a directional antenna. That was impressive too. Then they walked around the beam antenna holding the bulb and it would lite only where the field was strong enough so when recorded with a long expose camera the bulb created a visual map of the field strength in 3D space.
Hope you are doing well Larry. Noticed you haven't posted much as of late. Miss seeing all your videos. You are the person who made me get into ham radio. Now have my General, just passed yesterday. Studying for my Extra now. Hope all is well. Please give us an update soon. de NØTTI
That is great to hear and congratulations! I hope you are having fun with it all. I am still around and hope to post some videos very soon again. Got busy with other things in life for a while and outdoor things in the summer and not much time in the shack here. I am still active however. Thanks for your post and good luck with the extra class also! 73....Larry
Larry, Just wanted to let you know I really appreciate your videos. I share them with seasoned and beginner hams in our club. Keep up the good work. Terry, WA0DTH
Very nice video, i will be showing this in my circle. I like how simple yet technical you explained it, specially using examples of the flashlight,etc....love the video, thank you.
Nice demonstration, about you hams showed useful tips on field strength. Keep up the good work a fellow cb user with an interest in polarized antennas . also try building a moxon antenna for vhf good results a few bits and bobs .
thank you for a nice, simple demo; however, the meter was so illuminated that I couldn't see the needle at all; you might try putting it in shade or something so one can see the display better.
I have seen some dual-band directional antennas similar to yours that have both the 2m and 70cm elements on the same plane (i.e. both horizontal). Is there an advantage to having the elements for each band perpendicular to each other?
I do not but thanks so much for giving me a new idea for a new video, I might be able to do one on that meter, never thought about it before but I think that might be a good idea! I will see what I can do in the next week or two, kind of busy right now with outdoor activities but if I do I will give you credit for mentioning it and asking me about that! The meter was a home brew dyi by me so maybe I can show how I made it.
Good video Larry, the field strength meter looks a handy bit of kit to have, was it easy to calibrate?. I've never seen that tape measure antenna, what a great idea, must be a bit cumbersome for a 6m yagi though :)
colin campbell Yes, the tape measure might not work for 6 meters hi hi. The field strength meter is just a relative indicator so I don't have it calibrated to anything but just set it so the meter is in a range I can use to compare as long as I leave it in the same position in comparison to the transmit antennas.
I sure have a lot to learn, never knew it mattered the receive antenna had to match the transmitter antenna angle. ( both vertical or horizontal ) I like your style as far as a newbie can understand what your saying. Most videos I watch i get lost in the words and what the terms mean.
Great Vid! Plans available for that Yagi? (Same bands) Would love to build one, my poor little Baofeng HT's need all the help they can get! 73's, KI7QAB (newbie)
Hello. question: what is the minimum size of the iron pipe 12 meters for lifting the yaghi fm antenna Dimensions antenna gauge L*W*H: 5500*900*1760 MM Weight: 5 KG? thank you!
Hi Larry. Yet again, a very useful video that helps my understanding. I know this vid is a bit older and Ive watched before but lately, Ive been searching for a strong, yet sturdy and economical camera tripod for a similiar Sat Yagi but all I find is junk. Can you tell me what brand, and where I might find the tripod your using? It appears very strong, yet it turns fluidly. Any help is appreciated! Thx again... Josh N8TIP
Hi Josh, yes, that is a well made tripod I was using there, unfortunately they are no longer available, it was made back in the 1950's when they still made high quality stuff, ha. It used to be my dads camera tripod for his photography hobby back then. I have a couple other tripods around here, one I use for my Ipad for my video camera etc but it will break one of these days probably, not as good. So I have not done any searching lately to really know what it out there I guess. Sorry I can't be of more help on that. 73...Larry
I had a feeling it was from a different era. Maybe one day in the future that quality craftsmanship will come back full force in our USA. I can dream, right! Hey, thanks anyway Larry. You have a good one

Nicely done - good visual view of what the radiation pattern looks like.
Excellent demo to understood the difference between omni & yagi antenna.
Thanks for this. For being "not very scientific", it is the best Yagi demo I have seen on youtube.
Nice example. I had seen an older example where they lite a small bulb with a directional antenna. That was impressive too. Then they walked around the beam antenna holding the bulb and it would lite only where the field was strong enough so when recorded with a long expose camera the bulb created a visual map of the field strength in 3D space.
Yes, I remember seeing that video also with a light bulb, that was very good.
great demonstration. Not only can you see directionality but you can also get a sense of beam width. Thanks. KC3MBK

@@RadioHamGuy thanks Larry! Hope to work you sometime on the air! Would be quite good fun! All the best and 73s Larry!
Very good demo! Keep this up and you will give Randy, K6AGE some competition!
Very good demo. It was interesting to me to see some weak side lobes on the first antenna you tested.
Larry, Just wanted to let you know I really appreciate your videos. I share them with seasoned and beginner hams in our club.
Keep up the good work. Terry, WA0DTH
Thank you very much, I appreciate hearing that and am glad they are of help! 73...Larry

Thanks Larry...Very helpful and very educational. I really appreciate your videos...Keep up to great work you do for the amateur radio community!
Thank you very much Michael. As you can tell, I really enjoy the hobby and it is always great to help others when I can.
excellent explanation of the yagi beam pattern.
Simple but effective demo.
I like the vid and am glad for this level of explanation. I am much clearer now on some aspects that were a mystery. Thanks,
larry Good Job...
Great video. I can only imagine these people 200 miles away,
“Was that a UV5R Roger beep???”
🤣🤣🤣
It very well could have been, been a long time since that video! Thanks, glad you enjoyed.
holy poop you can make a antenna out of a tape measure that cool as hell man
Thanks for sharing. Very informative. Can you share your yagi construction details?
great demo!
Thanks for the fantastic demo.
Can you demo polarization ,vertikal end horozontal
Nice demonstration, about you hams showed useful tips on field strength. Keep up the good work a fellow cb user with an interest in polarized antennas . also try building a moxon antenna for vhf good results a few bits and bobs .

Hey Larry very well presented video, very professional and well explained. Thanks for sharing. Best wishes from north east England 73 M0DAD.

That is a very good demonstration!!

do you have a video of the make of the field strength meter?? or a circuit diagram?
I do not but thanks so much for giving me a new idea for a new video, I might be able to do one on that meter, never thought about it before but I think that might be a good idea!
