Thanks Mr. MuD for coming up with this idea! Mr. MuD is local to me and he loaned me this antenna for a ham radio presentation. It worked perfectly. The kids thought is was cool and one of the camadian forces signal techs that was present loved the idea as well!
Good idea. Its cool that you can adjust it too! Using these materials, you can make a window or door, pass through, for getting your coax to an outdoor antenna.
Aluminum tape is awesome. Every ham should have several rolls :D Copper is even better. I've never made a J pole. I was going to for 2m/70cm but I decided to go the flower pot antenna route. Might have to try it out for 6m since I don't have a 6m solution I particularly like.
Thanks for sharing this !! I don't have an antenna meter to measure SWR at the moment. 😢 What would be the lenths of the aluminium tape un the shorts and long part of the j pole and the optimum feed point to work with a frequency of approximately 140 MHZ .? What equipment are you using in this video to take the SWR measurements?
Total length is 59”. The short J part is 20.5”. Feed point at 4”. The best way to tune would be a Nanovna bit a swr meter would work. Or tune by the strongest receive signal. Have fun building
I don’t have a design per se but you can get close with this design to tune 70cm by adjusting the pick up point and rolling up the tip section of the antenna.
I was thinking 10m, 12m, even 20m. Maybe keep the bottom rolled up when it was too long for the band, roll up the bottom and top up with a moving shorting bar. There should be a good short point and length for every band, which should be markable with a sharpie. A 20 meter j pole would need to be, what, 45 feet up a tree?
They are great. I bought the cheapest one only to spend a week dialling it in to print a $2 part. 🤣. Don’t say I didn’t warn you. Honestly they are fun if you like to tinker.

No, thank you for sharing the antenna at your presentation. Hopefully a few of the kids get the Ham bug!
What's camadian forces? Do they ride on camels?
Good idea. Its cool that you can adjust it too!
Using these materials, you can make a window or door, pass through, for getting your coax to an outdoor antenna.
Funny you should mention that about the pass through. I’m currently testing a design using these materials. Thanks for watching.
Wes thanks for sharing this simple inexpensive adjustable rollup J-Pole!
Thanks for watching!
Nice club project. Thanks for presentation...73s
It’s a great project. Please message me if you would like a free live interactive video for your club on building it.
Nicely done, Wes. A perfect fit for your emergency go-kit. Aloha de Russ (KH6JRM).
Thanks Russell. Love your work and thanks for stopping by. Aloha from Saskatchewan.

I don’t leave home without the tape🤙🏻. A 6m J pole would be interesting, I just made a 10m one but still have to test it out. Thanks for watching.
"Mr. MuD's Antenna & Comedy hour!" 🤘📻⚡Love it Wes!! Brilliant! You gonna make a Moxon out of a spare chair too?? 🤔🍺
Thanks Tom! The chair is on my hot list.
HOME RUN! 👍
Appreciate the kind words. Thanks for watching.

I’ll dig it out and post some lengths. I used a Nano VNA to tune it. Thanks for watching
Thank you !!! 👍@@MrMudsHamRadioRadioTime

@@MrMudsHamRadioRadioTime Thanks again, for taking your time to send me this data. Have a nice day !! 🤗
Pls share a design for 2metet + 70 Cm combine J pole if possible.

Mud man this is awesome. 10m version next? :)
Funny you should mention that 🤣. I need to design a wide bracket to space the elements out. Should be doable.
Great video 👍🏽 73
Thanks! Won’t be the last on this wonder strap! 😎
@@MrMudsHamRadioRadioTime looking forward to seeing the outcome 👍🏽
What width of webbing and tri glides are you using also width of tape is it 2 or 3 inch
The webbing is 21/4”. Tri glides 21/8” and the tape is 17/8”. Thanks for the interest.
Wheres the 10 m rollable build video mate?
Still in production lol. Actually 10m dropped off the map over the last 4 months but I did see a blip on the scope yesterday. Fingers crossed 🤞

cool job
Thanks.
Dame, now I got to buy a 3d printer !!! lol VE1SK
