Designing Homebrew Yagis is Easy

John Portune (W6NBC) gives the SNARS members a fantastic presentation on the theory and design of Yagi antennas. No need for online calculators, John shows us a few simple rules for Yagi design that yield amazing results.

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

interesting and useful info. I am surprised with the hairpin system as I thought it would short out the coax and hence transmission signal and blow the transmitter.

Excellent presentation! Thanks for sharing your knowledge.

Love this approach!
What impact does the different diameters most store-bought yagis use for reflector, radiator, and the parasitics?

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 !!.

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.

Thank you 😃👍

Thanks for sharing!

Thanks for the video!

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?

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....

[@tomstrum6259]

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 ??

[@Gabaab]

antennas work on radio frequency, not light. optics and mirrors. have nothing to do with this.

It's just as easy to drill PVC pipe as wood.

[@rtsamram]

It is harder to keep the elements centered in plane
