I have a bachelors degree in EE and this is incredibly helpful. This sort of teaching is absent in formal education these days. Thank you.

Thank you so very much! You're that patient teacher I always wished I had when I was a kid with a hunger for learning such things. Now decades later I've finally found my teacher and I feel like I'm re-igniting some long forgotten fascination with this world of things---forgotten and left behind in frustration.

As always, Dave has a way of explaining the complex to a guy like me so that I can understand. Thanks, Dave! I'm taking on the Extra exam and using the ARRL study guide as my text. But, I always come running to this channel to get the classroom version which makes it all clearer.

I really appreciate the way the topic is presented and superbly explained.. Thanks a lot Mr. Casler.!

I sure do wish I had these videos when I studied for my licenses!  What a great refresher!

Superb David, I taught the RAE here in the UK using many of the tips of explanation found in your video series. 73 de John Allsopp G4YDM Washington, (Ancestral Home George Washington) North East England. Stay safe and well in the U.S.A.

OMG I love this guy!!! I wish I would have had him as a teacher when I was in school, I'd probably be an engineer rather than an SUBSCRIBED

[jonathanokocha]

I would like to design my own antenna for a Radar receiver!. Outstanding Lecture!!! My first introduction to Antenna Design. I started reading a textbook on Antenna. This video is superb and really summarized with all details. Thank you, sir!

[MarkRose]

This is by far the best explanation of antennas I have ever come across. I've learned more from this video than in countless hours of browsing the web. Thank you!!

May I suggest adding the topics covered to the video description to help others find this amazing video?

[nedwardj]

Thanks for having both thorough knowledge, and rock-solid presentation skills. You rock!

[emailshafihusain]

Very informative. And it is so rare to hear someone so articulate. Thanks! 73 from India. This is VU3BQY.

There are myriad ways to screw up the use of "myriad"....kudos to you, David, for knowing how to use the word correctly. Oh, and BTW, just an exceptional video on a very difficult (for me) topic. Thanks!

[RAndrewNeal]

I subscribed after watching one video. You're up there with w2aew when it comes to explaining this sort of stuff. It's also so much that I can't learn it all from watching a single video a single time.

[jedihakan]

Thank you sir, I wish I had courses thought by people like you.

[lydiafrancis]

Thank you from the bottom of my heart for this video. You made the pages in my manual come to life!

[harrisonfamily]

Dave, you do an amazing job explaining all this stuff. Spent many hours listening to you. THANK YOU.

[carmelpule]

Excellent contents and a gentleman as a presenter. There is  many hours of preparation for such a video. The priority points are mentioned and his experience does admit that practical performances are not always as theory stated, His best statement concluded from his experience is, " Everything can affect the performance of the antenna."  My congratulations on your presentation and experience.

[VanishingNomad]

Improve your antenna before investing in an amplifier = WRONG!!

The correct way is to invest in whichever one presents the sweet deal first. Get the other one later.

Great video btw!! I learned a lot from this one!

My old TV's antenna is a piece of electric wire hanging from it... It may not be the best, but man this things are easy to make... Great video by the way! Very informative.
