Its a great concept. But trapped beams or even an LPA are still kings of reliability. And when these go down in an ice storm or high winds ouch ! But for the guys with fat IRA’S I guess they keep StepIR in the green.

Thank you for the demo. We do not have anything on the TS890s or the TS990 on CQ Blind Hams. Would you consider doing something for us some time?

can you give the model and the manufacturer of the erection mechanism?

More money than sense 🙄🤦

Thats soooo cool!

very nice

well done im just seeing this and wow crazy cool

Can this antenna be ajusted manually to any freq? or is it only operational on ham bands even for recieve only.

Where do you get the mounting device of Folds the antenna down I’d like to get that where would you get that? I only found another one that only did a pill I need one that does 3 pounds thanks I’m very appreciative if you could tell me where you can buy that contraption

@KB3WFV Hello Brian I can't contact you via qrz that's why I'm trying it here. I'm from the Netherlands by the way so my English isn't perfect. I want to build the same antenna on my RV but please can you tell me something about the mechanism which retracting the antenna ? Did you build it yourself of can I buy it somewhere? Many many thanks.

Wow. Amazing!

Nice!. After a 3 month wait (labor shortages) I'm finally getting my little tarheel 2 antenna. It's going on my 4runner.

very cool install.....k6ipf..

ANY FEEDBACK?? How the electric motors perform on serious COLD WEATHER ❓❓🥶

What's the length of it? I live in a condo so i need to stay within the 40 foot width of the building

ALL MY GOD AND WHAT HASPPENS WHEN THOSE MOTORS STOP WORKING NO THANKS

Great video. I’d like to use this on my TH-cam channel that helps to teach ham radio. This will be for a show for new hams do you understand the value of first purchasing a great antenna rather than the fancy shiny radio. I’ll make sure and credit your channel as well as a link to it in the description of the show. This is a very well done video with the tape measures… Thank you! All the best to you and your family and thank you for helping to grow ham radio. Larry

fantastic antenna 73 from kb2uew

Amazing.

When has lowest swr been or equals resonance? It’s like trimming a dipole for best swr, it won’t be resonant, if it was it won’t be 50 ohm . This is the problem with step Ir owners! Very little idea of what a resonant antenna is, It is not a step ir. It adjust length for best swr not resonance or best efficiency which is resonance and some form of impedance matching to get back to 50 ohms. On a real yagi you set the driven element so it’s a resonant then you adjust the gama match or matching net work to get 20 odd ohms back to 50 ohms, A step ir just trims the antenna length , using reactance and a non resonant length to get a low swr. High performance antenna builders don’t build these things, these things are built for appliance operators with very little antenna knowledge, And those who know how a yagi works don’t buy these motorised antennas and the poor reliability . I guess gullible hams get sucked in all the time and the sharks only too willing to sell snake oil . I have a high performance antenna cause it cost me thousands of dollars! No you don’t! You have a expensive compromise that sort of works some ham bands , when the antenna works that is . Show how far the hobby has degraded, to the point hams fall for marketing hype over knowledge.

Great job

It can if you add an external bfo

Great video. Thanks!

This is such an excellent overview of the crane and the job that you do Jack. Thanks to both you guys are putting this video together.

Good stuff!

Antennas should never have moving parts, I've heard of too many guys with motor issues. Every antenna has tradeoffs and this one is expensive. I get it, limited space, easy of use, I would rather use a hexbeam and a vertical for 40m. 6m yagis are small and light weight. This antenna violates the KISS rule. I hope it works well for you.

I own the BigIR vertical and the steppir motors in both the EHU and the 80m coil unit sound exactly the same. It is normal as stepping motors work in literaly steps rather than lineal rolling motion. Hard to explain. Steppir are very technical but exceptional performers. Hard to find something that will work better to be honest.

Are you saying that you get that noise when you are tuning the antenna? And why were you and USB mode instead of LSB? Just curious. To the person asking if you had connected to controller ground to the antenna ground, aren't you supposed to connect all elements to the same ground potential?

Great video and antenna design

Hi Brian, Did you install the ground cable on the controller. If you did, i hope its not connected to the same wiring as your transceiver. Do get that controller a clean(other) ground. It did works fine for me. 73s Sascha PD9Z....proud urban user ;)

Nice video! How high do you have it? Was thinking on getting the DB18E with the 3 loops. I hope there worth it. Many tell me that they are very complex and when they break-down, are very expensive getting them repaired.

Good stuff buddy! Looking forward to it!

This is EPIC! LOL

don't forget to lower it. :)

Wow...this is really nice.... very innovative! Thank you for the video!

thanks very much nice job 73 from kb2uew

That was a good short video.

Seems akin to the Urban Sombrero from Seinfeld

What is the endurance of this set of antennas in FT-8?

Brilliant.

Why the inset of bent foil @ 0:37? Is there a story there? KL7IS

Nice

Could tell by your accent that your Eastern Shore Md, lol

Hi

On an existing roof would you place the steel mesh on top, then after attaching mount to the roof on top of mesh, coat with with Dicor roof paint? Would that hinder the ground plane? Last did you bond the ground plane to the trailer in any other way? ie ground straps down to the frame? I am considering the 400 for its reach on the 160 band why the 200? power?? 73's Thx k2bkr

Next time use stucco mesh.

Any link for that lift n lay please , as that’s just what I’m looking for

Ok my high standard in everything just got reset. Such a great job.

Damn man, very impressive. be sure to see my channel for radio art and fun.

Brian, amazing setup you got there!.. Would you mind sharing what kind/brand of motorized lifter did you use?... I would like to replicate for my home (HOA)... Thanks de XE1XZQ
