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.

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.

I used coax as per the instructions I used. A trap is a tuned circuit with inductor and capacitor. So I think with coax it's giving it more of both. Sorry I can't be more exact haha

Thanks, and thanks for watching

I have not had any issues aside from tightening one of the lower sections a bit. I've had several wire antennas including the fan dipole and trapped from my videos. No issues with the mast, very positive towards it. Lots of wind and cold weather up here too. Nothing but good things to say.

Yes I have one. I had to put screw clamps on all the sections to keep it from collapsing in the wind. And even then it appears to have shrunk about a foot. I have a 2/440 antenna on top along with a small crossbar and inv vees for 80-30 hanging up there. As well as wire for an inv L for 160. If it shrinks any more between now and summer I will probably drill holes thru each section and use a bolt/cotter pin to keep it up in the air.

@@Hank_W6IR put a hose clamp inserted through rubber hose above the clamps. See the dx commander for reference. Probably better than holes, atleast worth a try.

@@kj7iaz that's what I've got already.

Weird I'd think that'd solve it. It's been rattling around in my brain as a backup plan incase of slippage.

Glad you liked it!

Hahaha it's a lighting thing. Lol. I have aspirations to organize the garage enough so I can have a clean wall behind me, but.... life... lol

Yeah, I definitely wouldn't recommend this for a portable mast. It works great as a semi permanent mast though.

Great idea. Lol. Remember the holiday hole from several years ago? I see potential. Lol

Typically horizontal. Although technically it will work either way. There are better ways to make it vertical. I am in the process of putting a vertical video together.

I would have to find the docs that came with it. If I remember right it says specifically not to paint it (maybe to sell another one sooner lol) and it was coated, painting would keep it from operating correctly because of the tight tolerances.

Haha. Me too. I might do a 40. I can for sure do 20. Planning a vertical video then I could do a full loop when it warms up a bit.

It came in two boxes, the sections are long and heavy, I'd call dxengineering to get specifics on it. The hardware comes in a reasonable package.

@@kj7iaz thank you!

Thanks. I hope you share your project on here or on my Facebook page. Have fun!

Haha. Funny.
