I HEARD SOME GUYS ON HAMRADIO TALKING ABOUT A ANTENNA CALLED A DIAPOLE. ANY IDEA WHAT ONE COST AND WHERE I CAN PICK ONE UP? GUY SAID IT WAS A GREAT ANTENNA.
THANKS CHUCK CALL SIGN WPA1RIDE

It's made from stringing two used DIApers to a central insulator. Tie nylon line to the ends and put the feedline right into the middle. That way you can always catch the really interesting QSOs on the band. And don't worry about your meters. The dont work with diapoles.
Damn Skippy...that bunch done you right...Its is fine one. But you gots to tweak it a bit cause one side is for listenin and one side is for talkin'. Now if you listen more than you talk you gotta cut one side a little bit longer for better listening but if you talk more cut the other side a bit longer. I think you can figure on that. I heard people saying they spent near 200 dollars for a good talking diapole...and had for 'em years...sheot thats some damn fine business IMHO.
You can even get these damn listenin/talkin tweakers that you can put right there near your pillbox, you know sometimes you wanna go to and fro. But hell there's a bunch of things you can do, bout 10 million things and I think my wife just broke water so I gotta run.
Looks like a boy from here..damn somebody always wanting me to do something.
Good luck...gotta go.

It is VERY important that the diapers be USED.

Be sure that you insert the pin carefully through the center of the coax and to ensure your linear is working properly, have someone key the microphone and whistle as loudly as they can while you hold the antenna securely between your teeth. If you can feel your friend whistling, you will know that your have a perfect SWR match, if not touch your tongue to it just to be sure the next time he keys up and whistles.

WAIT IM JUST NOT GETTING THIS. ONE MAN SAID PUT A PIN THROUGH YOUR COAX BUT MY BUDDY SAID THATS A BAD IDEA AND PROBLY A PRANK. DO YOU MEAN PUT A PIN ALL THE WAY THROUGH THE COAX?? IS IT OKAY TO CUT INTO IT LIKE THAT? ALSO IM NOT SURE YOU UNDERSTAND MY FIRST QUESTION. ITS A ANTENNA CALLED A DIAPOLE. WHAT DO YOU FIGURE IT COST AND WHERE CAN I GET ONE? YOU GUYS WERE TALKING ABOUT DIAPERS AND I DONT GET WHAT THAT HAS TO DO WITH A ANTENNA. IS THIS A ANTENNA FOR TALKING OUT OR HEARING? WHAT I NEED IS A ANTENNA GOOD FOR SKIP WORKING ON HAMRADIO. I CAN HEAR THE SKIP BUT IM NOT SURE IF THEY HEAR ME NOW. WOULD A DIAPOLE HELP WITH THAT? THANKS CHUCK WPA1RIDE HAMRADIO CALL SIGN

A nail is even more effective, and lasts longer.

MAN ARE YOU SURE ABOUT ALL THAT?? YOUR TALKING ABOUT HITTING A NAIL THROUGH THE ANTENNA WIRE THE RGU8. ISNT THAT GOING TO BUST IT?? ARE YOU JOKEING AROUND WITH ME??
Come on Skipster...nobody here wants you left with busted RGU8. It would personally break my heart and then life would be so meaningless.
But iffen you did bust it you could get some more on ebar or whatever the hell that site it....cheap as all get out. Just click on Paybuddy...that's pretty cool cause you can just give 'em your socal celebrity number and you don't have to pay for it. It's like free, but the mailman wants a buck or two cause it really screws him(or her) up.
You gopher it.

HA MAN I GOT NO IDEA WHAT YOUR SAYING! ARE YOU MAKING A JOKE? MAN THATS PRETTY FUNNY.
As novice in the San Fernando Valley in the early 70's I would see Quad antennas everywhere. They just looked, more, Ham Radio, then a Yagi.
A place I pick up reefer loads, on Bandini Blvd, Vernon has a tri-band Quad on a high tower made of a telephone line pole made me decide that when I move into my new QTH up north some years from now, I intend to build one.

Quad danged it.
The problem with quads is that they are usually harder to keep in the air. In many parts of the country, they will break break much faster than Yagi's in an ice storm. Then there is the issue of how you feed them. Whether they are emitting a vertical or horizontal. Mileage will vary in the way you feed the quad, whether it is at the bottom, side corner, or side.
I still see some quads. People who own them will cuss them out though.

Yeah man that was just a joke...you know trying to kick back a bit...sometimes it hacks people up a bit, sometimes it don't...can't figure on it....
But hey back to that diapole...I think you meant dipole or just made a spelling error...I do that also...once again some people get bent out of shape about that to...what hey what can you do.
You ask alot of questions and that's good, but sometimes you need to do a little reading else where and hell you can figure most of these thing out on your own. Sometimes you can't and then you gotta ask but now I'm going around in circles.
Now you see you can get one of these books...an antenna handbook..and it has a buttload of stuff about antennas. The dipole is a real simple one. Well there is one simpler called an Isotropic raditior, but it just a pretend one sort of a benchmarking type thingy. But you read up on that pretend one and that dipole and you get where it just starts clicking.
Hell you don't even need a call sign to do that.
But sooner or later your gonna wanna use that thing and you need to do it right..Take on of them test and figure out where you can and can not holler...FCC will give you a thing with you call on it...and use the whole call not just the last two.
You do that and we'll all be right proud of ya.
Now get off my damn frequency, I got a net to call.
(That wa s a joke too, just FYI)

I got a quad story...
Back when I was a young punk ham in the early 70's, a bunch of us would do tower jobs for each other. There were 4-5 of us and we got quite good at it. One of the guys built a huge 4-element quad in his back yard -- had it up on a set of 8' A-frame supports for tuning and he was working the world with it just sitting in the back yard. 30' boom as I recall and the boom to mast clamp was welded steel plate -- weighed over 100 lbs by itself.
The day finally came to put it up on his tower; a 70' American tower. This was a lot like Rohn 25, but with welded tubular cross pieces. We had to drop the East set of guys so that the antenna could make it to the top. Tied a pulley to the top of the tower and started to raise the antenna with everyone still on the ground. The idea was to get the antenna to the top, tie it off and then have two people climb up and secure it to the mast. At the 60' level, the rope holding the pulley snapped and the whole thing came crashing down. It made quite a mess, but didn't hurt anything but our pride. Of course, the antenna itself was a complete loss -- pieces of fiberglass spreader all over the place. It landed with one element hanging over the fence in the neighbor's yard. We retired to the shack to cry in our beers.
But the rest of the story (as Paul Harvey would say)...
About 10 minutes later, a huge gust of wind came up. So great was this gust that we were actually glad the rope broke. Had the rope held, two of us would have been "up top" with 200 lbs of unsecured wind load. The neighbor had one of those 8x8' metal sheds in her back yard and this gust of wind picked the shed up and flattened it against her back fence. Never seen anything like it, before or since. Shortly after that, the neighbor lady came home and got a look at the back yard. She was PISSED! It took us 20 minutes to calm her down and convince her that her flattened shed had nothing to do with all the antenna debris.
True story. ;)

Pot, Kettle, Black.
Thank you for that story. It is colorful and I can see the whole thing happen.
The only interesting antenna story I can tell is that I put up a rhombic with W0RT one time for field day. Like 1978 or so. At least the 0RT was the same.
Well, the rhombic held and we made a few contacts.
