In reflecting on 2021 and the crazy start to the 2020's we felt it was an opportunity to reflect a bit. The topics covered are nothing new, and the same conversation can probably be held over-and-over again. Although the way it's presented the contents is not overly formal, the content is still true and often quite amusing to discuss. Here's our Top 5 antenna related experiences of the last 24 months.
First does my antenna need a power supply - no, previously the simple answer was NO, it does not. But things have gotten more complicated and there are new solutions out there that do. For example the Poynting https://poynting.tech/antennas/epnt-2/ .
Second: Can I use a splitter to create MIMO - no, you cannot. It does not work that way. A splitter just splits signal and you get a much worse outcome. Using a splitter-cable, where you jam two cables into one connector is an even worse idea. It may break your MIMO.
Three: Can I reuse old coaxial for 4G/5G - also not a good idea. Especially if it is an old RG6, you definitely need a 50 ohm cable for any 4G/5G applications (so thats LMR195/240/400). Also if you don't exactly know how the cable has been used, it may be a problem. It may have moisture damage/corrosion, or it may have kinks in it, that ruin the cable.
Four: Does 5G cause Covid-19 - No, it absolutely does not.
Five: Any old aerial will be just fine - sadly, no. It may be ok in a city with strong signal, but as soon as you go to a low signal area, you will have failures. You will not be able to connect.

![Why I Love the Yagi Antenna
- So, why do I love the Yagi antenna? Its all about physics and fundamentals, really.
The Yagi–Uda antenna was invented in 1926 by Shintaro Uda of Tohoku Imperial University,[5] Sendai, Japan, with the collaboration of Hidetsugu Yagi, also of Tohoku Imperial University.[6] Yagi and Uda published their first report on the wave projector directional antenna. Yagi demonstrated a proof of concept, but the engineering problems proved to be more onerous than conventional systems. (https://en.wikipedia.org/wiki/Yagi%E2%80%93Uda_antenna#cite_note-Brown138-15 )
So its almost no coincidence that Im here at the Golden Gate Bridge. I am on my way to Denver for the IMS 2022, and I just wanted to take a moment here to almost celebrate the ingenuity and engineering of the 1934 opening of the Golden Gate Bridge, which, only eight years earlier, the patent for Yagi antenna was registered by Yagi and Uda.
Im also just thinking Im still pretty tired after a 14 hour trip from Adelaide to San Francisco, so the whole history of avionics in 1904 really comes to mind for me today. So I just wanna basically spend a moment to celebrate the real fundamentals, cause in avionics, in the civil industry, and also in the antenna industry, Yagis have been established almost a hundred years ago. Its still one of our fundamental building blocks.
Im gonna spend a lot of time going forward on this channel, and just with RFShop in general to work on the principles, Also Black Art Technologies, just work on the principles, cause the principles are the things that never change, cause physics is physics. Yagi antenna is a absolutely phenomenal example of how things can be done.
