- My friend Tom VA3WBA takes this opportunity to show us his homebrew 15-meter J-pole vertical ham radio antenna, then gets on the air to see how it performs.

Wonderful video. Thank you for sharing. It was wonderful to see Tom make contacts with Poland and speak to them in their native language. Although I don't speak Polish I do have an affinity for the Polish as I lived in a Polish speaking household until the age of 9.
I love these ladder line j poles. They are soooo good. I made one for 10 and the bandwidth is huge. Completely worth the effort. Thanks for the video.
We were excited for Tom making contacts to his motherland!🎉❤
Kudos to Tom!!!! Thanks for sharing!
I can proof they are working as I use J-Pole‘s since years for portable and holiday style „expeditions“.
You can‘t do anything wrong, they just work. And when mounted vertical they are great DX antennas.
Thank‘s for the video!
73 and good DX, George AH6UN / OE4JHW
Thank you George and 73 from VE3TWM!
Hi Tracy,
First of all, I gotta say, that video was absolutely amazing! It gave me so much inspiration and more food for thought for Antenna building . And can we talk about Tom's excitement during his first contact? Loved it! I can totally relate to all the ham radio operators out there who enjoy getting hands-on with antenna building.
Thank you for your comment!
“pipeline to Poland” - love the joy in the face…
Yes yes and yes. I made one for 6m and the day I hung it up was the greatest day ever on 6m. I pulled it up into a tree-as I do most antennae.
I should re-hang it. I was portable that day. J-poles work just the same as an end-fed half-wave, if you look at the science. And I love my end-fed 1/2 waves too!
Love the adlib 002, better than 001 for sure 😂
I think I’m going to use 007 for any contest QSOs that I get dragged into.
Very Nice!
💥FANTASTIC. . . 💯👍
There you go.
Never thought of a J pole for HF bands! I work 15m just by a 40m dipole on third harmonic. Earlier I tried working 15m on an EFHW for 40 to 10m. Could not hear anything. Now I am able work a few stations on 15m, mostly during contest or special events. 73 de Jon, VU2JO

The J Pole is another name for the Zepp antenna. G7VFY.
Thank you for your helpful comment! According to an article on Owen Duffy.net, "The J Pole is a variation on the EFZ where the nominal half wave radiator is rotated to vertical to achieve vertical polarisation."
Nice antenna! Could you ask Tom for a drawing, please! 👍😊
I have posted the link but it is not showing up under here.
15m band antenna dimensions. I was not able to attach the link to the site with documentations.
1/2L insulated wire 6,66 m ( I cut it and then extended it good million times)
1/4 ladder line 3,15 m ( I cut it to 3,12m and it was too short)
22,5 cm from the connector to the feed point (once the antenna is tuned this can be probably changed as the last step to get near perfect 50 Ohms)
Is Tom Polish? he sounds like
Tak
