Sunspot Cycle 25: The Path to Solar Max
Thanks So Much for your Wonderful 'Simplistic' Approach .... I 'Sucked Up' Every Word .....Just could not get enough ..... :-) :-) :-) Very Best to You, Yours and All from ChCh, NZ
Great video. I love your presentation style. Great Job!!!
Well you guys say it's easy, you say it not me, can I have the specification for the 2,3,4,5 element yagi flat side antenna for 11 meter, please an thanks watching from Jamaica west Indies !!.
At 32 min, the very important part, he is cut short. Come on. Very frustrating.
Hmm, I always set my spacing to give a 12.5 ohm impedance where the 12.5 ohms was transformed to 50 ohms by using as the driven element a folded dipole with a wire spacing that multiplied the 12.5 by 4. This turned out to be common speaker wire. As far as being flimsy wire, it was taped to dowels similar to the fiberglass rods. Any method you know that works is good enough and I do like the simplicity of the method shown here.
2:31 😂 This didn’t age well 💉
March 2016 page 37 in QST
Thank you 😃👍
excellent explanation.
Excellent presentation! Thanks for sharing your knowledge.
It's just as easy to drill PVC pipe as wood.
It is harder to keep the elements centered in plane
Thank you, do you need to consider the width of beam when deciding on the element lengths? I.e.. is it simply the amount exposed or includes material passing thru the beam?
Thanks for sharing!
I still Don't completely Understand exactly How the 3 Element yagi works....Would a 3 Element Optical Equivalent using a Mirror reflector, 360° light bulb Source & Convex Lens produce an Easier to understand & Improve 3 Element yagi antenna ??
antennas work on radio frequency, not light. optics and mirrors. have nothing to do with this.
My accurately Calculated & precision Built/Cut & feed Match 10 element Vhf & Uhf yagi antennas Based on your Recommended model Performs only 75--85% as good as Commercially available 10 Element yagis.....What's wrong & how can I Recover the Lost 15--25% Gain potential ??.....Thx for all your Helpful info....
Hentenna = portmanteau of hen (変な) and the English antenna meaning "strange antenna" in Japanese. Really interesting video thanks!
Super video, thanks for posting.
Thanks for the video!
I am a new Ham (paid the fee today). My first radio ( bought before i should have) is a HT analog. My house is like a farady cage . I will need an antenna outside and getting it inside has to meet my wifes approval. I am thinking this is a good first step? It can get my on the air and if spend the time and and effort can then get a outside antenna or even base unit. Does this make sense?
Thanks for all of the great information 👍
THANK you for this. As a newly licensed and VERY urban ham, this gives me hope I can build a compact, portable antenna for balcony use. 73
Maybe you should research microphones a little more. Your voice sounds like it’s through a soup can and a string before you’ve transmitted it anywhere.
Specifically the introduction, not the bulk of the lecture
Also, a ClearZero can do ethernet by adding a $7 usb-ethernet adapter. Just remember to get one w/the micro USB connector...
I think Clearnode would better be described as 'turnkey', rather than 'commercialized', though it is certainly that too.
Iv had a CN for 4 yrs and it is truly awesome.
Awesome video guys!
Does Dr. McIntosh have an updated prediction on the strength and timing of the peak?
working on my first. good video!!
I like to Make if these for My SDR Play RSP DX Receiver!
I've run resonant (no tuner) Hentenna / Skeleton Slot galvanised fencing wire antennas on 160,80,40,20,10,6,2,70cm and 23cm for ten years, and there's a lot you've said that I'd disagree with. I agree though, the Slot is a remarkable antenna with big performance. I did the cube antenna, but formed in a circle instead - this does go very well. The biggest lesson I learned was the antenna is nothing if it's not resonant - attach a tuner to a non-resonant at your peril - an ordinary half-wave dipole outperformed it if I did. The 160/80/40 slots can be built inside each other and fed with one feedpoint for a jaw-dropper of an antenna - I mount mine with all four corners equal height above the ground, a cloud warmer as you put it, but it seriously outperformed any other DX wire antenna fullstop, as well wound any NVIS local stations' S-meter right off the end of the meter and caused many a disbelieving moment, especially with full legal into it.. Strongly encourage anyone to try this antenna - practice first with a six meter Hentenna since it is only the size of the hood of your car, and once you have the hang of it then progress on to a 40m slot, and then to 80 and 160, and watch the insanity... A word of warning, the Hentenna / Skeleton Slot is going to teach you how to use your analyser, this is a hard task master, as you will see. Rules of thumb - narrower slot is lower impedance, longer antenna is lower frequency, height above ground should be about the same as a yagi reflector distance.
Would love to see some of your antennas. Got a link?
@@dougtaylor7724 If you want to see one, then build it.
The vhf/uhf slot antennas mentioned as being on the concorde at 4:24 were in fact HF notch antennas. Also used on the DC-10.
How about a slot antenna for 80mts
Ever cool and educational. Thank you
Great video….thanks++++++++++
You've convinced me to make a "Slim Jim" rather than a colinear. I have some 300 ohm twinlead left from my days repairing TVs and installing TV antennas. Under 50W, I'm thinking this should work.
I have always found a Slim Jim to be the best performing antenna. Colinears are not that useful.
Also You can Make a Biquad Slot Antenna, It's two diamond Quads cut on a Piece of Metal,
The slot antenna, if you really look at it as a folded dipole! The RF current is traveling in the inside, using the skin effect of RF,
Great presentation, as a user of Allstar for almost six years, I feel one important feature was left out. Allstar is a duplex system and although the clearnode and SHARI devices don't take advantage of that feature, duplex opens up a lot of capabilities with nodes connecting repeaters and other devices.

Hi. I live in NYC. Everyone knows we have a lot of buildings here. I buy the Ed Fong GMRS J-Pole Antenna. My communication are way much better that before and I have 100 ft of cable, that not good, but this Antenna Work Prefect.
hi mate, thanks for sharing !!!
The shots are now proven to be snake oil, untested, unproven and cost many people their lives and refusal to take them cost millions their careers. Hopefully we will never fall victim to the greed of these pharmaceutical companies or government fools seeking power over the people. I wonder how this will be covered in the history books in 50 years when the dust clears. The damage to the economy is incalculable. We will never be the same.
Clearnode has dvswitch software installed that allows the analog to connect to digital. Clearnode runs hamvoip software for the Allstar connections.

I got a clear note recently and need some help how do you connect to a new contact also I have not seen these yellow or blue stripes when I use it on the previous connections that were done and testing before it was mailed out to me so I'm just a little bit hazy on these two processes if you could please clarify
Nice video, Tom. Great tp see my old podcast buddy is still playing with radios, 73, Barry K1BJF
Thanks for the presentation. It was a great overview. I’ve been on DMR for about 3 years. It looks like Allstar is link an analog hotspot. 73’s de KC1NE.
you can make a home base uhf collinear 3dbi or 6dbi or 8dbi or 10dbi or 12bdi or dbd. short one,s are more use in hilly terrain the longer the antenna are used for flat terrain.
are you guys trying to make a 477mhz uhf cb antenna
477MHz is Australian UHF CB. They also have conventional 27Meg CB .
