I hear Ape's voice in my head saying, "Now don't get it twisted, son." Seriously though, this was a great build video. It's helpful seeing the common mistakes that can be made.

If I had a nickle for every time I forgot to put the heat shrink on first I could buy a Flex 6600 and have change. Thanks for keeping it real, Jeem. It truly helps.

Nicely done Jim, well except for those small mishaps... lol! I would assume this antenna is made to be used 6-40. Looks like it works fine, congrats on another great product.

That a great antenna. love that winder base. I wound a lot of toroid's and so so at it. Chuck and Ape got me beat . I did stack of 2 and 3 T-240 toroid's with 10 AWG solod MAG wire . 49:1 for QRO end fed half wave. my fingers hurt 2 days. but doing 500 watt FT8 on 10/12 meters was fun. I ran 1/2 wave cut for 12 and fold back for 11 and 10 meters. bunch of ground elements like the DX commander antenna. ran up DX commander 10 meter pole. ran veritable like the Poseidon one but mono band cut 1/2 wave with 49:1 stack toroid core that one has the 100 PF 3 KV cap. ferrite stayed cool ! love the testing Ape and Chuck did. they did post some video's showing that ! for a small easy to deploy antenna this is all some. great POTA SOTA antenna . love that antenna wire. I buy it in larger AWG . I used DX commander wire on my mono band 1/2 wave veritable build . the half wave mono band DX commander antenna I made. that a fun kit you 4 made. 73's

Robert - I've been thrilled with the performance. I've been using it all weekend on FT8, and some phone, and it's absolutely tearing up Europe, SA, and Africa. Thanks for the support and thanks for watching!

I want a pre-made one by Mr Ape, cause Jeem buggered up the toe-roid... Ape is the toe-roid specialist. If Ape builds me a special one on video, I will buy one.😁👌

That was a good and informative review! One small correction, though: MultiJet Fusion is HP's brand of 3D printer. Distinguishing them is like saying "this isn't a pickup, it's an F150." Like you implied, though, MJF is a high-quality commercial-grade printer, and it uses nylon instead of PLA, both good things for the quality of this antenna. Thanks for the great video!
@FEPLabsRadio

Thanks for watching! FWIW - MJF is also an additive printing methodology - "Multi Jet Fusion (MJF) Similar to SLS, Multi Jet Fusion also builds functional parts from nylon powder. Rather than using a laser to sinter the powder, MJF uses an inkjet array to apply fusing agents to the bed of nylon powder. Then a heating element passes over the bed to fuse each layer. This results in more consistent mechanical properties compared to SLS as well as improved surface finish. Another benefit of the MJF process is the accelerated build time, which leads to lower production costs."

Have you tried one without close spacing the wires? I don't think the extra inter-winding capacitance is useful. You could also use one piece of wire twice as long, wrap the first 8 turns, sand off some enamel for the tap, and lay the final 8 turns roughly between the first 8. I believe that's easier than managing winding two wires at once. Then I'd use stranded wire to connect the tap to the BNC center pin (some of the left over BNTECHGO wire should be fine, and you don't need to keep the insulation) will help avoid stress breaks due to vibration or getting nudged in the go bag. (Don't let the solder crawl up into the body of the stranded lead, the point is for it to remain flexible.) If you leave the stranded tap connection long enough, you could also try the adjacent tap points, just to see what it does to the SWR curve. And speaking of the SWR curve, it would be interesting to see the real and imaginary parts of the reflection coefficient (or, equivalently, a Smith chart showing just the ham bands, labeled, or each on its own separate chart). That point out whether the addition of a capacitor, or moving the tap, possibly on a per band basis, might help. (Though it's still not going to be an efficient antenna on 80m.) (Maybe I'll snag a type 52 toroid and play.) Nice mechanicals, and nice video.

Thanks for the comments! This is the current kit CaHR is selling, so I put it together as designed. You're correct, there's a lot of different ways you can slice this loaf. Another guy I saw went down the path you mentioned, he built a multi-tapped setup.

I would not brag about an antenna that is above 2:1 for most bands. I use type 43 toroids for mine and they are under 1.5 to 1 for the HF bands.
