Hi, I'm sorry I no longer have the plans, however, the long leg is 19.25 inch from curve to tip. The short leg is 6.25 inch. The space between the 2 legs is about 1.5 inches. Rods can be made from aluminium, stainless or wire coat hangers. Adjust for swr as shown in video. Regards Paul
Pure genius. I'm thinking a single band 2 meter antenna would fit completely in the pvc pipe and work better for me. Putting a pvc tee close to the end nearest the antenna would provide a place to attach the mast without putting as much stress on the pvc pipe because of the weight of the antenna. Nice design... Bravo.
I'd have gone for Jacques Loussier's jazzy Air on the G String, though it may have caused an outbreak of cigar smoking, or made the viewer think the antenna wouldn't work, or something.
Simplicity is the genius of this design! excuse my ignorance (I'm a new ham) but how does it work on 2 bands? do you have to disconnect something to go from 2m to 70 cm? or will the swr adjustment cover this?
Hi Paul, great build on this antenna. I would like a copy of the plans please. Is there any way to receive them without posting my email address here publicly? Thank you.
cool build. i like the concept however you are using the wrong coax cable for vh/.uhf frequencies. i highly reccomend you use lmr400uf . that rg58 loss rate at the vhf/uhf i so high if you put in 5watts from a ht, you be lucky to get like 1/4watt to the elements... so invest in some quality LMR400UF you will be happy you did when your log book starts to fill up rather quickly on contest/field day. 73's k7sce
Depends on the length of the run. Based on what I saw, he has no more than 50' of cable, if that, bringing the loss down to 3.1 which equates to about half an S-unit. If it's truly portable, I would think it would be impractical to be carrying around more that 30'. Just throwing it out there for those who will set it up and transmit from several feet away. If you're going to stick it in your backyard and then make a run to the house, that's more of a permanent installation as far as the cable goes. In which case you could plant RG-8 or as you said, LMR400 with a disconnect for when you want to take it with you.
Agreed. The music is not a good addition. Your video is great otherwise. I passed my foundation exam a week ago and in interested in making antenna so great video. Keep posting and teaching people about this interesting hobby which unfortunately is loosing hobbyists. Lets all try and keep it alive for everyone to enjoy for years to come Thanks again 👍
Thank you for the video Paul! I really like your design, and the one I make for field use will be very similar. I see all the comments requesting "plans" and have to smile a little. Where have all the craftsmen with thinking/researching ability gone these days? 73 Rob
I was thinking the same thing.. Its pretty obvious how its built simply from the video, he explains everything about the antenna. The video should be used for an idea of what to build, but people shouldn't need instructions that say drill two holes in a T joint; if they do then DIY might not be a good idea.
Technician just beginning here. Thanks for this design. Since my HOA frowns upon almost everything, I'm considering your design not for field work, but just to avoid confrontation with them. 73 de HJ4JPG.
That looks fantastic! Thanks so much! I’ll sketch out what it seems but out of curiosity, did you build for the telescopic pole or the reverse? Never worked with one before, just curious! All the best! 73 de KJ5DVL
A nifty design, but no balun? As I understand, you might well have great swr, but radiating signal down the coax, putting less out if the antenna. New amateur here so constructive criticism welcome.
I'm going to build one of these. However, of all the DIY videos I have watched nobody talks about the minimum and/or maximum distance the curved sides of the rods can be from one another. This is baffling! If you place the two mounting points for the rods too close together isn't it possible you won't be able to adjust the SWR? The two ends will simply collide with each other. So how far apart should the mounting holes be from one another? Thank you! K9JPT
If you construct it for 2 M operation that will also work on the UK UHF 70 cm band as 2 x 3/4 waves. Also a very important point is the 1/2 wave dipole coaxial cable connection must have the centre core as the top vertical rod and the braid connected to the bottom rod. Great design and video report, 73's
Hi Paul , really good antenna and ideal for taking away in my caravan. Please could you send me the Dimensions and plan it would be most appreciated. Many thanks Darren
Hi Paul. Almost finished my portable aerial. Different design to yours as used material laying around in garage. Scrap stuff. 4 Part video. Cheers from old George.
Hi PaulThat's a great build. Can I be cheeky and ask you for the plans for this antenna? Happy for you to reply on here or share on email if you prefer.73s Tim
Thank you so much sir,,, it s a great presentation,,, i love d idea that it can used in a quick installation and almost anywhere,,, and m planning to build 1, however in my case, would it b better if 2 or more stacked dipole b phased together?
i am not a ham but very interested but one thing i thought i read is that you would need a ballun when building a dipole fed by coax as it is unbalanced?
Looks like a great design I will be making one soon. You could modify the pvc length from the pole and add a reflector element that's 5% longer then the long element and velcro it to the and it would about double the gain making it a 2 element yagi that's directional in a broad way and will help your 70 cm also. I make one similar for 70 cm that's portable from 3/4 square tube works greaty
This is a brilliant bit of do it yourself. I have been looking for a good portable dipole for my emergency kit, and this is it! I would very much appreciate it if you were to help me locate the plans. Thanks in advance!
