- Hello! In this video I show you my homebrew multiband vertical portable antenna :) Me and Paul OM0WT went to try it in the field how will this antenna perform. We were impressed! We had many QSO's and two special - India! This vertical worked also with 100W without any problem :) All european QSO's we was made with 20-50W max.
I plan to improve more my design and then show it again.
I hope you enjoy this video! 73 and please subscribe if you like ;)

Very nice build, Paul. I built something very similar about three months ago.
The technique of shorting out the unused part of the loading coil is a real "Q"- killer! You will probably get even better results if you attach the crocodile clip to the feedline inner conductor and tap UP the coil, leaving the unused part of the coil "floating" below the used section of the coil.
Yes, if we shorted turns on an ac power transformer, there would quickly be blown fuses or worse...certainly a lot of heat. Yet, I keep seeing this done with RF inductors and wonder why they just don't "select a tap", not short windings. I always leave the start end open, and select the proper tap.
Wow! The nature, the excellent quality of your video, the antenna performance, and your presentation as well...compliment each other, amazing!
Oh! Thank you so much for your very kind comment! It motivate me to make them more 😊
Thanks again! 🖐🙂
I'm proud to hear our district operators vu2wew KERALA operator
We thanks them for opportunity to have this beautiful QSO's! ;-) 73, Paul
OM0ET , could u explain me which is group. Keerthan said our district operator. Which type of this communication? & where to be used. Thank u for Yr Time.

Been building coil tap verticals since the early 80,s. Quarter wavelength at 80 meters. Cut it , wind it up and tap the band you want. I use a shunt coil at times as needed. 102 inch stainless whip on top. Usually works better close to the ground with a ground plane . It's the 1980,s version of a screwdriver antenna.
Excellent little vertical Paul!
I just tried to make something very similar: For the 40 meter band, a 6 meter telescopic fiberglass fishing rod with a tapped loading coil at the bottom and 8 pcs 6 meter long radials - mounted on top of a sturdy video tripod. I probably got too few turns on my coil and need to extend it to get my antenna to cooperate a bit better since I only got some JS8 contacts in central Europe on 10 watts. 🙄
Your surroundings are very similar to mine! ☺️

Thanks! I used two online calculators on the internet to get this numbers. But still I have to working on, because it doesn't work as I want :) Wish you good luck with your own vertical! 73, Paul.
Hey Paul, this was an impressive video indeed. Liked every bit of the experiment and yes, the awesome sceneries of Slovakia. When you improve this all band vertical portable antenna, please make a video and alert me. Have a great day ahead.

Вот это я понимаю мастер на все руки.
Very nice! Like your design and looking forward to more. New subscriber, hello from California.
Very much enjoyed your presentation on making and testing your homemade vertical antenna, and very nice scenery to boot! Thank you for sharing!
Looks similar to my antenna, which I call the WRC Clone. I have a video on my channel that shows my antenna. When I built mine, I had a 10 Meter Hamstick that I wasn't using, so I got some wire, PVC pipe, weed eater twine and connectors and started building. Since my original build I have changed a few things. My antenna doesn't use the clip like yours I have a collar I adjust up and down just like the WRC and I can turn from side to side to get the best SWR. I have since removed the Hamstick and went with a 102 inch telescopic whip. Great video! Juddie - WD8WV
Excellent video, Paul (and Paul)...great looking antenna! I really like the quick-disconnect ground radials; first time I have seen that. Certainly helpful when a storm is approaching! 😀 Anyway, great work Paul(s)...look forward to your next one. 73! de WX0V
Hello Scott! Thanks again for watching this! Yes I try to design this vertical for SOTA and portable operations, where is weight, dimensions and deploy time very important :) That's my goal! :-D There is still a lot of work on it... Have a nice day! 73, Paul.
good work!
The telescopic whip looked longer than 2.70m.
At least that's how it looks in the video. :)
73, Ingo
Congratulations. Thanks for the video.Glad to have worked you guys. Very happy to see the little killer you have home brewed there. Hope to work you again. 73 Jith ,VU2OY
Hello Jith! Nice to see you here :D Thank you for the nice DX contact with our small setup! ;) Hope to work you again! 73, Paul.
Hi Jith, thanks for the QSO, it's been my first India SSB QSO and I enjoyed it!
I love it! Very clean build!!
Hi Paul
Maybe you could increase the efficiency of your vertical on lower band by adding (with an alligator clip) some horizontal wire. It will look like an inverted L antenna.
You have many trees around.
Thanks for sharing your experience.
73, Med CN8YR
Hello Med, that's a good idea!! Thanks ;-)
looks absolutely beautiful there mate. GM2EDX
👏👏👏👏👏👏 Best regards from Malaga, Spain looks a very nice anthen!!😍😍😍😍😍😍
Muy interesante su antena y por lo que se ve trabaja bien... felisitaciones 73
Saludos desde Chile
¡Muchas gracias!
Well done lads
I like your builds very much. I like to try this myself. Gonna find out your measures for building it.
Paul,
Excellent portable antenna. How did it load on 75 Meters? What was the bandwith on 75 for each adjustment?
I use a similiar antenna on my truck, but it only works from 40 meters on up to 6 meters.

Frank
Hey Frank! I am still working on it. This day wasn't tune on 75m. Only 20m 😊 It's just a prototype or startpoint for my next vertical 😉👍73
This is an interesting video. Did you have an auto tuner to adjust the see or just move the wire on the antenna to get the best SWR. Also would like to know what the SWR was. At no time did you say. Anyway a nice portable antenna. Looks like weight and might be able to do SOTA with it. Would like to know total weight of everything. 73 Clark KG7LOI.
Yes, sorry I totally forgott to show tuning and SWR in this video! :D The SWR from edge to edge of 20m band was 1,5 and in the middle was 1,1. Pretty good! The weight I don't know. I didn't weigh it because it's not yet finished antenna, but I guess it's completely without tripod about 1kg or less :) I design this antenna specially for SOTA to get max. frequency range, portability and quick setup on the place and still not too weight and small as possible. :) 73 and thanks for watching! Paul.
We didn't had deployed ATU. Was not necessary 😉
Great homebrew antenna...beautiful location too.
Hi, wondering how long are your radials that you will connect to it?
Do you have different lengths of radials for the bands or do you just use one length? 73 Jörg
Radials should be lower closer to the ground I think, nice setup, can't wait to see your improvements, 73s AA2BD
A very good antenna for outdoor radio adventure. I subscribe your YT Channel. 73!
Good video!
I use similar antennas working from an apartment in Akron, Ohio USA!
40 meters (General Class portion) seems dead lately, maybe because it's Summer. But your video is encouraging!

Thank you so much! 😊 We moved to the village already. I plan to made a new wire antenna now.
@@OM0ET You are very welcome! And may all of your endeavors result in success.

Beautiful location for portable operation. Antenna works great! WD0DUD
Thank you! 😊
Thanks for video. The antenna certainly works! One question I had please: where did you obtain or how did you make the metal connectors at each end of the PVC pipe? I think you said the top one had a 3/8" thread for the telescopic whip and I assume the bottom one has a standard tripod 1/4" thread?
Thanks Steve! I was made this mounting adapters of aluminium on the lathe. :) I use it also on my Magnetic loop antennas :) Thanks for watching and 73! Paul.
Can you make a video for wieving how attach the vertical pole to the screw of the easel?
Great video. Jared, KW4JLB, here in Georgia USA. Seems yoiur antenna performed very well for its first run. Can you list out what improvements you would like to make, and why? What were the challenges? I am sure you will make a follow up video on this but curious as to what that may potentially cover.
Good job!
Thanks!
Velmi pěkně provedená anténa. Gratuluji
Lev OK2PLL
Ďakujem. To je len prototyp, ale pracujem už na vylepšenej verzii :) Snad sa mi podari onedlho aj videjko :)
Paul buenos dias..saludos desde colombia. hk8 rkf..una pregunta..me podrias informar en que posicion de la bobina va la toma para cada banda que tu hayas trabajado...gracias por la informacion y un video muy didáctico. 73,s JAVIER
What is the difference between tight wire reels and spaced wire spools?
Hello sir, how long wire that you need for build that multiband loading coil? and how many band (40m, 20m, 11m) it's work?
It is my friend VU2WEW ADERSH, DE VU2TAH
Good luck Paul with your project. Keep us updated on your progress.

Hello my friend! Yes I will. There is still a lot of work on this project... I will try to keep you informed ;) 73 and thanks for watching! 73, Paul.
Very cool. What sort of SWR were you getting on various bands? Just curious to know if you used an antenna tuner at all during your testing. I didn't see anything connected to the radio. For a compromised antenna it performed wuite well.
Tuner is not required on this antenna 😊
Well done and thankyou for sharing. You have some good projects.
Is better an N connector or if possible a SMA connector, not a BNC connector
Thanks for the video. I think this is what I need and should make this one. Bravooo... 73! 😃

Good luck Born with your own antenna project! 😉👍
Hi Paul, I heard you today on the IOTA contest :-)... could you tell me if the telescopic antenna is always full streched an all adjusting is to do with the coil or is there any adjustment to do in the telescopic part?
73
Martin (DG4BAD)
Paul thank you for sharing the video really nice antenna maybe you should Market it and sell it the different amateur radio locations thanks again
Thanks Joe! Yes I plan it but when it will be finished and fully functional :) Thanks for the nice comment and 73!
Very good! It reminds me of a outback mobile antenna (but with a longer driven element). I have a couple 5m and 3m fiberglass poles so I can make and do the same. However I also have a DX Commander which I recommend you have a look at too just for ideas and inspiration maybe. :) The DX Commander is a very good multiband but, your antenna is much quicker to deploy.
Thanks! I design this antenna for SOTA and portable so quick deploy, light weight and multiband is my priority ;-) Thanks for the nice comment! :) 73
Can you recommend a good video,article,book or website that teaches about antennas. From basic idiot guide all the way up to pro showing TV, sim networks, etc functionality.
succes full paul
Hi Paul,
I am new to amateur radio and very much interested in your home made multi band vertical. I would like to make one for. If you have made any improvements, please give me the details too. Thanks
Спасибо! Отличное видео!
You ere the best
Paráda Chlapci, také niečo by sa mi teraz zišlo do 9A, ale už to asi nestíham urobiť. 73 nech sa darí. Jano om8jp
Šťastnú cestu a ešte šťastnejší návrat Jano!
Greatful so much friend.congrat.
Thank you! 😉👍
Bom dia amigo gostaria de saber as mediadas desta antena para eu construir uma
Nice video. I see you've used insulated (coated) wire for coil. With your coil assembly (soldering?), are you sure you are not getting any shorts between turns?
73 de SP7PSD
Yes Pawel, I abraded gently only a small upper part of the each rounded wire of each turn in the coil. The isolation remained on the sides and bottom part of the wire, so the wire do not touch each other electrically :) Thanks for comment! 73
Very nice video. One question for you. Is your callsign OM0ET or OM0WT? I thought it is OM0ET, but you keep saying Whiskey Tango in the video. Thanks.
😁 I am OM0ET but in the video you can mostly see of OM0WT - my friend also Paul 😄 I was a cameraman, hi hi... Thanks for comment 😉👍
OM0ET Ah, mystery solved. Thank you. Your home-brew antenna is awesome!
@@Openwrt2023 Thank you but it's just a prototype. I work on it 😉👍

Hard to say :) at least is this vertical capable more power. I was today in Humenne, it's only 25km away from my city :) 73, Paul.
Super antenna easy to construct happy to hear that u are able to contact vu2 I want to know the running length of RG58 cable whether I can use 10 meter so that I can put it in the first floor and to operate my icom 718 73s vu2rpc prem kovilpatti tamilnadu india.
Thank you Prem! :) You can use 10m long coax too. My coax was about 5m long, but I don't know exactly. ;) 73, Paul.
Nice video 😀👏👏
Thanks!

bravo
Hi Paul nice one again keep up the good work ,de Mm0aup 👍
Thanks Peter! 😃 How is your Loop working? 😉
OM0ET hi Paul not been out and about with your loop since last summer ,but just got cirro mazzoni baby loop put up two weeks ago at my home qth,but they forgot the 24 v power supply for the tuner so can’t use it yet ,it’s got to come from Italy so don’t know when it will arrive ha ha ,hope your staying safe ,and working some good dx,de Mm0aup peter.

Hey, Paul. I built a similar antenna, and I wanted to ask you, how long are the radials you put in? HJ1HMV from Colombia
Hello Hernan. I have used 3pieces 5m long radials. 73, Paul.
Ótimo trabalho gualidade total bazuka Foz do Iguaçu pr Brasil caminhonista também
Excellent video thanks. (If I lived near remote woodlands, I'd be there before the sun came up to record the dawn chorus in wonderful stereo.)
Oh yes, that would be great! I can imagine that how it would sounds like :) Maybe once, because I live in the city and forest is far away from me :) Thanks for watching! 73, Paul.
That tray-table built into the van seat the most interesting. I have not seen that in the United States.
73 DX!
Now I am interested in what were the bugs and what improvement(s) if any did you already conduct? 🙂
Thanks for vedios and qso demo but where did you adjust the antenna for swr and how that part is missing on vedio.
Yes I know :D sorry about that! But I plan made another videos about improving this vertical so I am sure that measurment will be included already :D Btw. the SWR on 20m band between edge to edge was 1.5 and in the middle 1.1 that's pretty good! 73, Paul.
@@OM0ET welcome, we will be looking forward to it.
Clever design and great built. Congratulations. I wish had your skills (and toolshed probably) to build this. I don't, so I've bought the JPC-12 instead, which is close in design to this, but yours is better with the longer coil.
Does the 2.7m tripod give a real advantage vs. radials on the ground? I had been told that radials like yours, going 45 degrees, not on the ground, had to be tuned to 1/4 wave.
I will try to make your atenna design brother my callsign DV3CAL where didn't you buy your expandable antenna whips expand 2.7m
Very good job. Please make the plans available when you're happy with it - for a price, of course.
Thank you 😉👍 It's still just a draft 😊
Buenas tardes, desde Cali, Colombia, te saludo. Hay posibilidad de comprar una unidad de esa maravilla de antena.
Apply for the antenna patent immediately and i'am sure you will make a lots of money. Do it or i'll do it. 🤣🤣🤣
Excelent anyway. BRAVO !!!!!
