Did this video help you?

Mark Ruhland: Very cool!!!

WD7N: I've made several "cantennas" over the years, The easiest way to solder the center conductor on a SO-239 is to tap it out of the connector then solder the wire in place. Once done just tap it back into place in the connector. That way you don't melt any of the insulating material around connector and have a better solder connection as well.

Andrew Polezhay: I wonder how to change the SWR if Bank of coffee will be slightly smaller:? 73! de UT1ZZ

Electronoob: brilliant :D

721NorthernAlberta: Amazes me on how you whip an antenna. Good going Dave.

Gary Harrison: I hope you are not using standard 60/30 solder. If so, you just put lead in your mouth.

Vienneau Marcel: could this be used for a outdoor scanner antenna ?

Bryan Miller: Bob Heil had it right in one of his books he said "every thing that exists is because someone tried it"

Lew Bloch: This guy has amazing soldering technique.

Vasile Pop: Very neat! 73 de VA6POP

TREE HUGGAH: now that is pretty cool.i put that one in my favorites list.great work sir. watch for a coffee can antenna in all the catalogs for the holidays,ya better get your patent together!!!! 73,KB3YJO

Jonathan Sawyer: I wouldn't hold leaded solder in my mouth. Who hasn't got that secret stash of "proper" solder?

N0rthwestRadio: This would be a great way to introduce the concept to others and what a great platform to do it with. After the experiment you have the delay lines to use to build a Quad or Yagi type design using the same principle. The next step would be set the cans in a three point triangle each having its own delay line to a control point. Using a switch setup to excite certain feed to change the patter without moving the cans. Am I being to hard on ya? Grin... Phasing is fun experimentation. Apply to HF!

Tianyi Xie: Dave you are wasting this coffee can. It can be made into a 2.4 GHZ cantenna.

purplemutantas: I just built this antenna today. It works better than my Ed Fong J pole! It's pretty amazing what a coffee can and coat hanger can do! We are going to be doing some simplex practice on our local new operator/tech net. I may have to stick my coffee can up on my mast and see how that works out. Thanks for the video Dave. 73

Adam Dickson: you could always just solder the wire into a pl259 no need for a coffee can then easier for handheld use

Brian Shriver: Very cool project. I have to get an analyzer like that.

Bernie Edwards: cool idea....I'm going to give it a try!

purplemutantas: Simple. It's just a quarter wavelength element. So just calculate the wavelength at your chosen frequency and divide by 4. It's pretty simple stuff. Stuff you really aught to know before you start building antennas. Dave has a great video on dipoles. Check that out. It will give you some antenna fundamentals.

humaxf1: Nice project. Try a metal dustbin next. A tip to prevent breakout on the other side of a hole, get a scrap piece of timber on the opposite side and press against the force of the drill. You'll have a burr free finish.

TREE HUGGAH: BRAVO!!!! what a great project,you should patent that idea. 73,KB3AUM

Celso Lina Da Silva: Please could send me by e mail all measures of antenna metal pot. even that was not clear to me the measure. Email: Matrixtwo@msn.com

slamdvw: A safety tip: put a wire nut in the end of the radiator to eliminate the sharp point... and make it easier to see.

FannyAckin: does it work better with decaff

Joel Tan: For instances, if i am using a 4 copper wire as a base support for the 4 holes in the SO239 socket, what is the differences of using a 4 copper wire or a coffee can as a base support? Does the base height matters if i am constructing a 433MHz antenna. I was about to ask about the same question as the comment below.

OneStudPuppy: Awesome. This project is one of the reasons I became a ham. I like to try off the walk ideas and share the try and see idea. 73

MarvinMcGill: What kind of bit did you call that gold 1? Will it work for making a hole in the top of the van roof for a MNO mount?

Bass Assassin: Would you email me what I need to make this I want to build one fdny3forty3@gmail.com

Nolan Rollo: I didn't see anyone comment on this about the filing but the first day I used a metal file in front of an electrician I got yelled at because I pulled the file back against the metal. If you push (cut) and lift up (instead of sliding back up on the edge of the metal) you won't flatten down the teeth on the file. :)

purplemutantas: I just had another thought about cans. Coffee cans are number 10 cans. Other things come in number 10 cans. Tomatoes for example.

VE2ZAZ: Some of the baby milk formula powders still ship in metal cans.

cougarhunter33: I think Best Choice still puts coffee in metal cans. I'll have a look when I'm at the store tomorrow. KB0MLR

vetham100: i am going to use a folgers can, i want my antenna to be strong :)

Dave Tadlock: That's a good idea. I left the insulation on and so don't have too much of a sharp tip but still a good idea. Thanks for watching and 73! :)

purplemutantas: The coffee I buy comes in metal cans! MJB still uses metal. I have a newly emptied coffee can. I am going to have to try making one of these. I will also have to take a look at the dual band coffee can antenna. It would be interesting to see how the coffee can antenna compares to my Ed Fong J pole

Nick Leijenhorst: Hey Dave, amazing channel you got here! I was just wondering... Why do you need impedance in an antenna? Or is it the impedance in the connector?

James Wood: My Maxwell house coffee cans are metal...

John Zenick: The round pizza sheets that you can buy could work too...

not2fast4u2c: NEAT Idea !!! Resterants use big cans for Vegetables That would be a source for a can

N0JRJ's Ham Stew: I was thinking you were gonna make a 2 meter CanTenna - using the inside of the can to make if directional. But hey, that is a great idea as well! Thanks for the vid

Alford Santee: Nice I followed these direction and made my own ! I used a 1 gallon paint can!!

WX9DX: Thanks for a cool project for emergencies.

bill ethier: Do you think your cable length had something to do with your element length? I have stuck a 19 inch piece of copper wire in my portables BNC connector and have hit repeaters 25 miles away or so. How about doing a video on portable antenna experiments/ projects... alot less simple than mine though Thanks, 73's KB1YDB Bill.

therealmylesracing: Dave great job on another project! Another happy follower. "Can" u guest amate how many watts it could handle? Thanks '73

purplemutantas: What would you be using for the ground plane?

Stefan Terblanche: i have done this using a coffee can but place the radiator on the inside and make it a 1/4 wave antenna for vhf and uhf and you have a directional antenna aim not done jet still doing some testing.

kernowrock555: Women say..us men can't "Multi-task" !....... But just look at the skills from a 3 handed solderer!! :)

TheLioncave: Any idea how to determine the length of the vertical element if i am to make a 433Mhz antenna using this idea?

gegarpa123: Could you indicate the size of the jar? in project description To the public is not English thanks

joksonu1: Just wanted to say thanks for what you do for the hobby with your projects and videos. I used your video for a guide for the 40/80 Meter Inverted V. Works just as well as my Alpha Delta DX-B sloper and the Inverted V has less noise on every band. I can't wait to try this one! Thanks again and 73. KC8YTP
