Yes. In years past we have done that with my kids and my family's kids. It's fun. This was a local project we did last year, but unfortunately couldn't make happen this year.

Its been goodm i haven't had a chance to make any new videos. Kids, work, life. Lol. I've been hoping to though I want to do an endfed half wave. Then put it up vertical. Might be a dx machine! Lol.

Which one? I have one on the website and one in the ham radio toolbox app.

@@kj7iaz Ham Radio Toolbox app, I guess, it doesn't matter. It calculates by numbers

@dogikata yeah the calculator displays both. Then the tuner just has you trim or add by the same as your original input length. So if you use meters, the adjustment is meters, if you use inches, adjustment is in inches. Thanks for supporting the channel!

Its definitely easier these days with the flood of information readily available to us. I try to simplify the concepts to encourage people to jump in and try. I like to say, antennas are an exact science that just have to be close to work. Thanks for watching and commenting!

Thanks for the comment . It's been great. 1 it depends on the antenna, I switch antennas alot so I use zipties, or electric tape. 2 it should work great for that. 3 yeah definitely need guys, 4 at 2 height should be good, since you are doing it more permanent, another set so 3 total (or more) would be better. 4 I have seen that. But minimally. I just tighten the cam Locks more and it's fine. You'll be able to tell if it slips, your guys will look loose. Then you can address it, if you don't mind the extra time and effort, the hose clamps are probably helpful.

Thanks!

I agree. Always find a bug or two in practice sessions like this. It's always fun to practice. I should do more of these types of events, but it definitely is hard to find the time some days.

Nice! Yeah it used to be called build a pi, check it out. It's basically a huge script to load a Linux distribution with ham software. Check it out.

Glad to hear!

Its designed to be a backup, quick solution. A digital version of a paper log.

Hey if you don't mind , email me at kj7iaz@gmail.com. maybe a screenshot or something too. I'll look into it.

Also I just uploaded a new app, and had to reconfirm my account, so maybe it has something to do with it.

@@kj7iaz Thanks anyway would have love to use the format/

It's a great option. Make sure your updated, if you email me I can help you better. Let me know.

@cliftonhead9665 i just realized, are you talking about the spreadsheet from the website? If so email me and I can send it as attachment.

I have a series on antennas. They hang from this, check them out.

It'll be pretty narrow, you might do a flatter lower inverted v for just 40, it'd be nvis, but most likely still usable with great success.

Thanks.

I didn't ground the mast. Or the antenna, my equipment is grounded though.kind of. Lol. I operate portable frequently and don't ground those set ups, so figure why do it at home.

Nice. Yeah it comes in different packages if I remember right. Let me know how it goes.

Its still working great. Check out my antenna Playlist, they all went on there. I know it's been a few months,hopefully it's still helpful. Did you get one?

It's been working great for. Check out the other video to see how easy it is to build. 10/10 recommend

Haha. Yes, but they can work temporarily.

I liked the idea of less weight in the air and more down low. Might be a fun experiment to compare both ways though.

Maybe temporarily. Its not a substitute for a tower. But you could use the bigger section and not go as high and it would probably work.

My pleasure

My pleasure

Thanks for the comment and sub.

Not sure, the manual might say. I'd have to measure it. But it is bigger than expected. Works great though.

@@kj7iaz Thanks for the Reply

I use for a variety of antennas. It's great for experiments and testing. Check out my antenna series.

Check out my antenna series.

You're welcome

Haha. Amature cameraman

Ain't that the truth

Just do it - or is that for shoes only?

Yeah it works very well that way.

The whole kit came from dxengineering.com

Thanks! I'm glad you did.

It's great. It's been up since the trap dipole video with no issues.

@kj7iaz nice after your review I have one in my DX engineering shopping cart

@vinnyboomba9948 haha yes. My dxengineering wish list is full. Maybe they will take note one of these days and send me some stuff to play with haha.

Thanks. I appreciate it.

Haha. Although the hardware would hang up.

Nice. They sure do move alot with out guys. Lol

It's been great. The first month or so, I adjusted a few clamps otherwise it's been perfect. Rain wind snow.

@@kj7iaz thanks! That’s great. Thanks for the video.

Thanks for watching

I'll be doing a video soon that will help with that!

This was k7mem.com

​@kj7iaz Unfortunately that website does not excist.

Weird. I just tried it again and it comes up.

Indeed!

Holy cow, that'll be up there. Show some pics to the Facebook page when you put it up.

Thanks

Thanks. I'm very glad I got it. Works perfect for my setup. And it's easy enough to experiment

In the video, I mention the website I used. In the calculations there is an effective length of the trap, just subtract that from the length you would cut for a dipole. As you move out, it adds up. So you'll have to keep track. It'll be close and fine tune by slowly trimming. Hope that helps. Feel free to email me if need be, I can maybe explain better.

Ok I got it, the webpage tool you pointed to suggests the effective length. "The Effective Length is the estimated amount that the next-lower-frequency leg of the trap antenna must be shortened to obtain resonance"

@@kj7iaz Am I wrong? After putting this down in a spread sheet it looks like I may not be able to use the 12m and 15m bands after the 10m band. The length of wire needed gets negative when the bands are too close together.

10 and 12 are delicate. 10 and 15 should be ok. You can play around with the diameter and length of trap. Find get a combination that has less effective length. Also. This is only one way to build a trap. Could try a different version. Or experiment on your own, a trap is simply an inductor and capacitor in parallel. You could also do a fan dipole, it might work better for the bands you are trying to use, or even a hybrid version. Use traps and fans.

I'm sure you meant so239.
