tom7601: The cable plug a PL-259. The mating socket is an SO-239... :)
Shannon Duffy: Hi there it be interesting on learning to build a uhf antenna with simular
stuff. How would i be able to do it?
lppessotto: hi mate how are you wat was the SWR like on the antenna ????
henrique umeoka: It will not work probably !... A dipole antenna must have each sides
diffentes according to the frenquency. PU5HLU.
SV Seeker: Good for you! I wondered who would ever not have a pieces of PVC pipe
stashed away in the rafters or under the house. :)
SV Seeker: @boatingisfunUK Wish I could help but I don't know anything about radios.
In fact, that antenna is the first thing I ever did for a radio other than
kick it when it was not working. As for the coast guard my experience has
been that it's best to not talk to them. :)
LCmusicBlog: What would be the outcome if I used rg-59? would it not work at all? is
there a way to use rg-59 and change the ohms, by adding something else? all
I have is rg-59..
Jonathan Endersby: I built this and it worked about better than my handheld's antenna.
SV Seeker: It will not be as good as a high dollar antenna but it will likely do. And
yes, you be able to hear the harbor traffic within at least 7 miles of you,
maybe 20 on a good day. Post back and let us know how it works out for you.
SV Seeker: No sorry, it worked great. You must be an engineer. I learned long ago that
most engineers are only good for getting that last 10% of performance and
generating 90% of the information that just muddies the water for the rest
of us. Check out our videos of Argonaut Jr and you will see it in action.
Donald Heathcock: Email firstname.lastname@example.org and email@example.com so feel free to email
TheUncleDougger: The conector on the radio is an SO-239. The PL-259 is the one that goes on
the coax cable.
Radionut R: @submarineboat you made a dipole antenna! That is an antenna with both side
the same length! Look it up on Google! BUT then you taped the two sides
together to make it one wire! !! Why?
SV Seeker: I wanted the wire glued to the end of the pipe. Did you just pinch the wire
Emiro Veronese: I build my boat antenna following this man instructions: it works good!!
Yes the connector is suppose to be assembled in a different way, but how
shown in the video can work too. Thanks buddy!! Only suggestion I have to
make: use a longer pvc pipe so the signal can reach a longer distance.
LikeToMakeTools: That should work OK for receiving, but as others have pointed out it is not
very good for transmitting. An antenna not properly matched to the
transceiver will limit it's range and may even blow out the transmitter
stage. The length of RG58U should be cut at multiples of the desired
transmitting wavelength. I would also use the type of RG58U coax with the
copper braid, which can be soldered to the PL259 connector body. The
antenna should be calibrated (adjusted length) for minimum "SWR".
SV Seeker: Sorry. I have no idea.
SV Seeker: So enlighten us on the proper method.
SV Seeker: Right, both ends are the same length but that are not taped together. The
core goes up, and the exposed braid goes down. Now the braid does go down
along side the coax and it's taped to that. That is not the recommended
arraignment but it works.
Tviki007: How many decibels in the antenna?
T Mann: Less then $10? The coax (50feet) has to be more then $10. The pl259 coupler
is about $2. The GOOP glue is about $5. The PVC pipe is about $4. Add the
soldier, black tape and the time: Cheaper to buy a new one. And you can
safely transmit with a new one!
SV Seeker: I did what? Speak English. :)
kd4adv: SO-239 is the name of the connector on the radio that accepts the PL-259
muddymuddymuddmann: pl259 is the male part of the connection. so-238 is the female counterpart
of the pl-259 conmnection. nice antenna and video. thanks. MUDDy
Donald Heathcock: Ok here is to all you people I'm Donald heathrooster I live in caruthersville
Missouri I work on all cb radios and handhelds I also sell real antennas
cheap and I work on antennas and make antennas and I made this one cuz I
talk on marine radios and all other radios and I hooked this one up just
like he showed and I reached 35 miles over land I operate over land on base
radio for boat or house either one pluss I talk on my handhelds even tho
your not really suppose to but everyone does..
Corynick86: The proper way is to put braid and all up through the reducer, then fold it
down over the reducer. Then thread the two parts together. you should now
be able to see the braid through the four holes. Use the holes to feed in
the solder to bond the braid, connector, and reducer together. Then go
ahead and solder the centre pin, trim if need be then thread the sleeve
over the lot.
Radionut R: What did I miss/ You made a dipole then taped it together? /
Radionut R: @submarineboat Well you might be surprised! Try it BUT don't forget you
need to be on the water in your boat when you do! (ha ha ha) I am going to
build me one today Thanks for the great how to video
Michael Marzec: I'm sure someone has mentioned it already, but your UHF connecter was
installed incorrectly. For receiving it may not cause a problem but if you
plan on transmitting it could cause issues. The braid of the coax should
have been folded back over the reducer not folded over inside of it. JS
smokinghull: Good video, simple solutions usually work! BTW, this antenna is called a
SV Seeker: Sucks when you do it wrong and it works anyway. :)
CKJEntertainmentServ: why wouldnt you have used REAL PVC caps rather than using the goop? a 10'
stick of 1/2 PVC pipe is LESS than $2 a piece, 2 caps, ( instead of goop )
is less than $1, and i just paid $15 for 25' of rg-58 cable, and $3 for the
pl-259 and the reducer. CHEAPER than a new one.
Mike Abraham: Godd, Great, and best and priceless DIY Instruction ! I build right now and
works great for my Stabo Magnum M. Thanks
Mark Mcnutt: The PL-259 is the male, the female UHF connector is a SO-239. Ironically,
the "UHF" connector is less than ideal for UHF. The PL-259/SO239 is better
suited for HF bands. Breast vidz. What was the VSWR like?
SpectreOZ: Voilà... and there you have a "quick and dirty" VHF coaxial dipole antenna,
thanks for going to the trouble of uploading your build process. If you
like that style of construction then maybe you would be interested in the
VK2ZOI "flower pot" antenna designs as well albeit a little more involved.
BTW the braid in this antenna type is actually the counterpoise not the
gooza77: It is nice that you show all steps to your viewers but you reduce the
quality and range of that antenna by doing what you did with the braid. You
should slowly push it back so it widens and roll it over the rest of the
coax (in the direction of the connector end). Once it is rolled over just
pull the braid so it tightens and secure it with some tape. I also fold
back the aluminum foil over the braid since I get better results compared
to the antenna I made without the foil (I cut it off).
Shannon Duffy: thats cool i got a 1 meter 10cm pvc pipe a 15mm and some coax cable will
try and let you know how i went
LCmusicBlog: Im going to build mine for free tonight. Total cost = $0.00 I have
everything I need, from "junk" as people call it. just have to clear an
area and get to work on it.
SV Seeker: Copy that Uncle Dougger, thanks for the correction.
Radionut R: O i see what i missed! You folded it back (the shield) along the coax in
the PVC and you made a folded dipole! Have you tried it on transmit? thanks
for the video!!!!
SV Seeker: Thanks for the tips.
Corynick86: Now you have a nice electrically and mechanically sound connection. In a
marine environment it wouldn't hurt to fill the connector with some white
di-electric grease and put some goop around where the coax jacket meets
SV Seeker: Sorry, no idea. We only used to the talk a short distance from a submarine
SV Seeker: The PVC pipe does not matter at all. You just can't change the length of
the exposed wires without knowing what you are doing, and I do not know
what I am doing. :)
lppessotto: thanks mate just that we had a guy come in the other day and he is using
the same design and we had it On our SWR meter and the lowest the the
reflected power we could get was 7 watts reflected cheers mate ...
SV Seeker: You must work for Radio Shack. I spent less than $10. I also enjoy building
things and apparently living dangerously.
SV Seeker: Thanks. Glade it worked for you too.
Philiphfisch: Good job boy !!
JWalkind3: Thank you very much for this video! I'm gonna try this as soon as possible
to replace my small antenna on my old radio scanner.
SV Seeker: Ha. Also no idea. If you want to talk antenna's your're going to need to
find another source. This is just a quick cheap VHF antenna that worked
great for me.
Chef de NYC: Thanks! I'm more info ultrasound type of work. I learn most of the stuff myself online. Just only recently start looking for a school to make things "official". Hehe
