Fixed Wireless 101: Antennas without Maths or a whiteboard

- In this video, Jarrad explains antenna fundamentals without maths, relying on analogy and example alone :)
Whilst this series is aimed specifically at those interested in Fixed Wireless Broadband, this video should be of interest to anyone who has wondered how antennas worked, and especially those who have found typical engineering texts to be complicated to understand.
Jarrad cuts through all of the complexity, reducing Antenna theory to a few simple tenets that anyone can understand and apply to the study of antennas.
We hope you enjoy the video, and please let us know what you think in the comments; questions are welcomed! :)

I am researching changing from a slow dsl isp who provides only 5Mbs download to a fixed wireless through a cellular signal that reaches 10-25Mbs download speeds for almost the same price, and trying to really understand how the antenna they will put on my house and point towards the tower will work. I think your video is helpful, but I will most likely watch it a couple times to grasp how I believe ATT will provide this service and how it technically will work. I'm thinking not to do it in the winter and wait till the trees green-up to be sure the technician can get a strong signal, or I may get screwed by summertime. Thanks.
what would be the best setup for penetration of trees for fixed wireless internet?
Trees are your enemy full stop. 2.4GHz *may* go further than 5GHz but it may not depending on noise in your area, and it has a larger fresnel zone aka more potential for tree interference. The solution is height, period. Sorry, Jarrad VK3BL :)
no problem i keep hearing that, is a more expensive radio, better as well? or are the all the same as far as penetration, thanks for your input by the way
2 type of antennas.
Balanced antenna system. Examples" dipole, yagi, loop antenna.
Unbalanced antenna system:
Examples : monopole, co-linear, ...
Please correct me, if I am wrong.
Thanks for the informative video..

Dear Bahathir, mostly correct. :)
Collinear arrays are made of dipoles. That said, you bring up a good point in that I didn't specifically dwell on the concept of balance and how it affects feed lines. The reason I didn't was mostly because the video was made specifically for IT people interested in Fixed Wireless, and the radio system as a whole tends to be integrated (no feed lines etc).
Thanks for the comment as always, and I hope you and your family are well :)

Thanks for the correction. :)
BTW, I am also an IT guy. :)
Thenks for the greetings. Same to you too, Sir.
