thx man

does it work in Australia? our frequencies here are 65-550 Mhz?

I would like this so much more, it would be so much more helpful if the video were LIT well. It’s so difficult to see the work you’ve done with such poor lighting. Also, when you took apart the UHF/VHF antenna, you didn’t say whether or not it is amplified (it seems to be since there is a blue light on)…

Great job. Looks good.

kzolady August 1, 2010 at 12:28 am

Could be wrong, but it should work

kzolady August 1, 2010 at 12:54 am

Thanks for this solution. I tried 4 purchase antennas, and the original coathanger antenna,and was unable to receive VHF. With your version I am able to receive VHF and had a use for my old amplified antenna. Works great. Kudos

OK the idea ! ( and nice the quick final comment ).

does it work for an analog tv with a converter box? i live in cali, nd cant even watch fox 11 my tv doesnt picks it up at all. or channel 13, or 7 wich should be local, nd have the best shows. i cant afford a new tv.. please help? i haven’t watched my simpsons 4 way too long.!!!

god bless u man

abdolali77 August 1, 2010 at 3:07 am

nice tatoo man

BennyBeezyMoney August 1, 2010 at 3:34 am

Again man, I love you. You have a talent in explaining things …..I listened to both of these videos intensely ……. then you said watch Desperate Housewives in HD & I crapped my pants laughing. Whatever Great Video …God Bless

If you splice rabbit ears onto the UHF coat hanger antenna, (A) connect them at the transformer connection point, and (B) make sure they’re treated as separate antennas and not an enlargement of the UHF antenna. This is done by connecting them with a shielded wire (like cable) or a coil (curly spiral wire). Just connecting them anywhere on the UHF antenna throws it out of tune.

beeper43 August 1, 2010 at 4:18 am

Thanks for making this video. I stupidly threw out many antennas over the years, even one last week.

DJoCoeur August 1, 2010 at 5:13 am

Thanks for giving more details
i just got the ANT-585 so i can try this

mx0069 August 1, 2010 at 5:49 am

Nice work dude!! Keep it krafty!!

edmmman August 1, 2010 at 5:54 am

What if I only have the rabbit ears? Can’t I just use the end of the two wires and screw them against the coat hangers?

jkeelsnc August 1, 2010 at 6:31 am

Good job. I like clever things built from common materials.

jkeelsnc August 1, 2010 at 6:33 am

these kind of projects are always interesting. I may very well build one of these using coathangers and wire at some point. For the moment I am using a 4 bay antenna built using a wooden dowel as a support with 4 Radio Shack Bowtie antennas snapped onto the dowel. Actually I have the wires crossing over from the top and bottom bowties and then of course a transformer in the middle between the bottom and top pairs. I can tell you that it works very well as I receive long distance TV stations.

kireum August 1, 2010 at 7:10 am

copper always better and don’t need any amplified rabbit years just attach any rabbit ear antenna and have a signal adapter that can receive two sources of signals.

jeremyschevy August 1, 2010 at 7:45 am

great video but do you have to have an amplified antenna or does it have to be plugged in to work?

gyoungsta15 August 1, 2010 at 8:32 am

please make a video to show how much channels you recieve and rescan so i can see how many channels u recieve

ATLien174 August 1, 2010 at 8:35 am

Cool, but could a regular powered VHF antenna be used instead of the “HD” one?

starbucks246 August 1, 2010 at 8:42 am

hi coooooooooooooooooooooooooooooooooooooooooooooooooool

HonestCharlie210 August 1, 2010 at 9:18 am

Thanks. I really need PBS here in San Antonio. come by tattoo shop at Zarzamora & Fred. rd maybe you can help with crap reception we get

eddytsp August 1, 2010 at 9:47 am

[1/2] Nice on integrating a VHF solution into one of the popular designs. It seems many are not paying attention to their local markets or have an incomplete understanding of where their local channels will end up on the radio spectrum. I’ve seen comments claiming all DTV will be on UHF, which is false, so thanks for bringing that to light, however, I have to disagree about the use of the RCA guts on your antenna…

henriqueumeoka August 1, 2010 at 10:26 am

It will not work probably !… A dipole antenna must have each sides diffentes according to the frenquency. PU5HLU.

submarineboat August 1, 2010 at 10:58 am

That’s what were looking for. Thanks for the feedback Cory.

Corynick86 August 1, 2010 at 11:47 am

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 connector.

Corynick86 August 1, 2010 at 12:00 pm

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.

submarineboat August 1, 2010 at 1:00 pm

So enlighten us on the proper method.

Corynick86 August 1, 2010 at 1:45 pm

Didn’t say anything about not working, and it’s probably not too bad. BUT your ground doesn’t have a good connection and over time the dissimilar metals will tarnish and voila! burned out radio finals :) Especially for a marine type antenna that will be exposed to the elements.

submarineboat August 1, 2010 at 1:53 pm

Sucks when you do it wrong and it works anyway. :)

Corynick86 August 1, 2010 at 2:20 pm

You didn’t install the PL-259 connector properly

submarineboat August 1, 2010 at 2:59 pm

Copy that Uncle Dougger, thanks for the correction.

TheUncleDougger August 1, 2010 at 3:06 pm

The conector on the radio is an SO-239. The PL-259 is the one that goes on the coax cable.

KC8YOQ August 1, 2010 at 3:56 pm

@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

submarineboat August 1, 2010 at 4:15 pm

Right, and no, we have not tested it for range. I doubt it breaks any records. :)

KC8YOQ August 1, 2010 at 4:24 pm

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!!!!

KC8YOQ August 1, 2010 at 4:53 pm

@submarineboat OOPS You are correct! i need to watch this again because i missed something! Great Idea BTW

submarineboat August 1, 2010 at 5:50 pm

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.

KC8YOQ August 1, 2010 at 6:12 pm

@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?

submarineboat August 1, 2010 at 6:23 pm

I did what? Speak English. :)

KC8YOQ August 1, 2010 at 6:51 pm

What did I miss/ You made a dipole then taped it together? /

njllllljon August 1, 2010 at 7:44 pm

Grrrrrrrreat Video!
