I think its a great piece. Very practical way of teaching. I do not know your targeted audience but I do think you touched so many things in a little time. I recommend that you make series of video on antenna basics for beginners who may be choked at a point with antenna terminologies used in this video.

I really liked this. I'd be interested in more technical content. Looking forward to more on antennas & radio.
Loving the curls... Nice explanation guys.
Hay Darren, I work a Cell Tower Tech I know a few things about cell towers, that was a grate shot of an LTE tower... there is a Diffrence between a 3G, 4G, and 4G LTE, there is one thing you should know thought if you're that close to a cell tower, your cell phone may not even be using that tower. There is a minimum and maximum distance that each cell site is setup for per the carrier .. For exsample: a cell site in the city, the antenna will most likely be angled to have less distance but a stronger signal becuse that carrier can have more of them but then you could be out on the Highway out in kansas (or Some country side) and be rolling up on a cell site and all of a sudden your call is droped and that would be becuse the antenna's are angled more for distance.. anyways i can talk all day about Cell sites and how they work
Awesome videos right before work! Thanks!
I keep hearing him say "Foreign Stints" then realizing he is trying to say "For Instance" - Love the info/show thanks!
The more elements you have in front of the driven element, the flatter the transmitted signal becomes, and provides the forward gain of that signal, but as you add more directors, you narrow the RF signal, meaning you must now be more accurate in antenna aiming if you are doing point to point systems, or to a distant receiver, such as a remote mountain site.
I could listen about antennas for hours and hours together!
I'll put in another vote for a days worth of radio/antenna/electromagnetic theory. Full understanding of underlying principles is after all the basis for almost all forms of hacking.
Awesome episode. Hit on some very good points!
Very informative discussion thankyou!
lol. This was cool because I'm an electrical engineering major. Right now we're going into Maxwell's Equations and stuff in physics, so its pretty neat to see some of the physical application of this stuff.

Is there any really good open source software for designing antennas?
Isn't 1/2 wave to 5/8th wave optimum for a dipole and a full wave is actually worse?
FM antenna theory, ' Fu**ing Magic'
Great Job. This is good information.
