How to make an Amazing 3 element Moxon Antenna for the 10m band, PART-1. 

We used to have a 3 Ele 20M wire moxon hanging between trees.. fantastic towards one single direction from low height ( 8 mtrs. ) . It was modelled with 4nec2 and worked perfect.

When I've worked with braided kevlar I will mark the line where I want to cut then lightly coat both sides of the mark with rubber cement type adhesive. Allow it to dry and then cut. It gives a non fray end like on shoe laces, no need to buy crimpers. You pretty much need to glue before you cut to prevent fraying.

Tons of great information in this video, great job Chuck 👍

@KK6USYHamRadioAdventures A handy tip for working with kevlar braid (and similar heat resistant cordage) is run a few dabs of superglue/ca along the cord where you want to cut it (so your cut point lands in the middle of the glue line), give it a quick squirt of activator and then cut the line in the middle of the now hard glue run. It bonds the fibres tight so your freshly snipped end doesn't fray, making it much easier to thread into the heatshrink/ferrule or any holes you want to thread it through. I find the thinner types of superglue work best as they wick in immediately and don't add bulk to the diameter of the cord. If you specifically want to add bulk to the cord ends however, you can sprinkle the wet glue with sodium bicarbonate from the baking supplies instead of using spray activator. Hope this helps, enjoy your videos across the pond here in the UK! 73's, David MW7KAX

Thanks Chuck. Always great to learn a new build!

Another way to get that loop to go through the ferrule is to use a short piece of light mono. Make your loop in the rope, and loop the mono through the loop in the rope. The ends of the mono are much easier to thread through the ferrule, and act similarly to a cable snake. Once both ends of the mono are through, pull the ends until the rope loop comes through the ferrule.

The dimensions between bare copper and PVC isolated wire antennas are expected to change a bit as the isolated wire has a velocity factor of ~0.95

Great build Chuck. Can't wait to see how this is finished and how it works on the air.

I like your attention to the details in this video Chuck. I am deck envious, you have a sail loft, antennas do take up some room.

Really helpful Chuck. This is similar to the links I have on the Hex using the 2mm Mastrant cord I have here. I need to get some of those crimps and a crimper. Look forward to the finished article 👍

Great attention to detail on the build mate impressive

Waiting for part 2!!

Perhaps try a drop of glue where the cord is cut? Possibly super glue. Let it dry for a few minutes before cutting. Should keep the ends from fraying. 73 N4MJR

Chuck you always have good videos about antennas, Thanks. You might try a piece of tape where you want to make a cut on that cord.

Chick Norris of antennas!!!!

very cool - never seen a moxon w a director before, good stuff!

Very interesting video Chuck. Thanks

Awesome Chuck. Nicely produced video. ;)

Based on my NEC modeling of a Moxon, adding a third element is probably not worth the effort or cost. A Moxon has approximately 12dB of directional gain. Adding a third element might add another 1-2 dB at best. The point: check your simulations and decide if the incremental addition is worth it for you. The advantage of a two element Moxon is it's simplicity for the gain you get.

Thanks for all your informative videos. We should get together for coffee sometime or have a QSO. You are practically a neighbor at only 5.7 miles away. Earl WB6JAF

I dip the end in candle wax and then make it into a point.

Love the attention to detail of fabricating the cords and elements Chuck. 73 - KF6IF

why not use a lighter to burn through the rope. Wet your finger before you touch it. Then you don't need superglue.

Looks interesting. Can't wait to see part 2. Link for the kevlar string?

I realize it's very unlikely this is going to be permanently installed, nor make much use of the 400lb test nature of that kevlar cord.... but in case anyone is thinking about leaving their kevlar cord outside for a long time. Kevlar is UV sensitive. It starts out that yellow color, and turns brown in the Sun. Once it's turned brown it's lost over 1/2 it's strength. Looking forward to the build details on this one. I'll likely build one! Looking at the archived website, I noticed this: "Tf cable 2x 6.79m, 75 ohm with v.f. 0,66. '. Is this to be fed with 75 ohm coax, or is that the phasing for the stack of two of them? 73 de w8tam

Chuck, do you have a link for the silicone wire?

Good morning
