It's a Dish? It's an antenna? No, it's Dishtenna....

The Green Dish is truly an eco-friendly product. It is not only changing the way the masses watch TV in the 21st century, it's helping the environment by being made from recycled materials.
See More Here: Revolutionary Dishtenna, DTV Green Dish, Goes Nationwide to Provide Quality Free Digital TV

The website offers no tangable information on the performance of the Dishtenna, but I have to say that I admire the entrepreneurial spirit. Up to 80 mile range?!? I believe that, even my 5" diameter copper tube antenna has that. Does it perform equally well on UHF and VHF? I doubt it! Can you always guarantee all of the local channels? Is a rotor included in istallation? What's the beam angle? What's the gain? Questions, questions, and more questions!!!

Having personally built and installed antennas for various services including television for decades, this antenna looks like a real turkey to me. Caveat Emptor.

The DTV Green Dish is unaffected by weather conditions. In fact during rain storms you might receive more channels due to the atmosphere condition.
Can anyone detect a condradiction within those two sentences?

Hey, I can tell you Dan from South Florida likes the Green Dish even better'n than his Radio Shack directional HDTV dish antenna! He gets 70 channels, and says you should pop down to Ace Hardware and see it in action!

[edit: Dang! Just noticed the first name of Green Dish CEO is also Dan, and he lives in Florida too! Just a little co-ink-ee-dense, I'm sure.]

OK, seriously dumb question: If a parabolic dish is the best reflector for satellite, why isn't it more common for OTA antennas?

Actually, A dish is excellent for UHF - If the dish is about 7 FEET in diameter, and assuming you can even find a UHF dish.

The CM 4251 is (was) a 7 foot diameter parabolic UHF TV antenna that is widely accepted as the most powerful production consumer UHF TV antenna ever manufactured.

Details here: Channel Master 4251 Tribute Page

I would say that this "thing" -

I bet it's no better than your run-of-the-mill $20 2 bay antenna. Reminds me of those "rabbit ears" they used to sell by mail order in the Sunday paper supplements with the UHF loop made to look like a satellite dish.

The elements definitely have a unique shape. I wonder if that is the part he got the patent on?!? Otherwise the dish is just acting like a refector like would be made of mesh or bars on a normal antenna. (Higher than normal wind loading baby!!!)

Anyone want to donate the $200 to be able to put this thing to the test? ;)

The dish is acting like a normal reflector, by the looks of that pic it doesnt even have a focal point. As MrPogi said, true UHF parabolic antennas are much larger. If you want to DIY one Ive heard people use a bowtie at the focal point of a C-band satellite dish. Of course unless all your channels come from one site (Most of Australia, but few places in the USA/Canada), then there is no point trying that as it is -VERY- highly directional (and has some awesome gain figures too)

The Channel Master 4251 is a real antenna that provides awesome signal level gain, but 'the green machine' will always be a turkey, AKA junk.

Have google will travel ...

Welp, at least we know Dan has been doing this for almost 4 years. Dang hard to find any reviews on 'em though. This guy must be related to Dan ...

HTGUYS reviewing Green Dish soon

I heard the HTGUYS podcast #533 is getting to samples to try in Irvine California stay tuned for their reviews! If this thing works Im dumping my old channel master and gettin a Greendish!

Ah ... I don't think you're listening. The pros are saying this is a HUGE GREEN SCAM.

Yes, I heard the htguys. They have no expertise in this area.

(Here's the podcast, HDTV and Home Theater Podcast - Podcasts - Podcast #533: Amazon, Dishtenna and Google Chromebox
Skip in to about 39:00.)


For $299, I will install a custom antenna system that will get anything this magic antenna gets, and probably more. Most of the installs I've done cost far less.

At least they don't alter physics too much, they claim (up to!) 80 miles but also say it will drive 8 TV sets. 80 miles is about the limit for any antenna without tropo, and I'm sure they could hook 8 sets to this antenna and get signal on all of them - if the transmitter is very close and strong.

And what about those (like me, and most of America) whose channels don't all lie in one direction? Every location and installation is different, and requires a different solution. What about VHF? Where's the specs on this "magic antenna"?

There is no such thing as a "One size fits all" solution, there is no "Magic antenna". Period.

You'll be working for him soon!

Didn't you read what the guy in the hangar said? 180 degree beam angle! Most you'd ever need is two disharoonies.

Every location and installation is different, and requires a different solution. What about VHF?
I know I read SOMEwhere 35 mile range for VHF. Can't recall exact wording.

Where's the specs on this "magic antenna"?
Well, I think one of you guys should write to Dan and get a free trial dish to test. Even if he refuses, that would be an indication, since he acceded to the htguys. ("Home Theatre guys," I think.) I'm not the guy. Don't have the equipment.

There is no such thing as a "One size fits all" solution, there is no "Magic antenna". Period.
Wehhhhhhhhhhhhhhhl! Not until NOW! :flame: :flamewar: :flame:

Vhf question answer for Pogi

Hi Pogi thanks for your interest. Actually, it is very superior with vhf in fact it will get fm, lovhf,hivhf,uhf,and shf. Its dedigned that way because we plan on bringing future premium content in the shf frequencies encrypted for a price similar to on demand net COs.

:welcome: DTV Green Dish!

Are you the CEO/inventor, Dan Rivera? Can you speak for the company?

This is a very impressive media blitz, and the head guy in charge here would very much like to know the patent number for this invention! I tried looking for it, so far without success.

Also, do you have any objective data on this antenna system? For instance, Antennas Direct claims for its new DB4e antenna, a peak gain of 14.5 dBi, a front to back ratio greater than 18 dBi, and a 60˚ beam-width. Can you provide similar data, and the test conditions you used to obtain the data?

You've been working with this system for a long time. Have you done any shootouts versus well known antennas from established manufacturers? Please share the results!

Thanks In Advance,
Rick

Guest,

What is "shf"? Super-High-Frequencies that are NOT used for HDTV in North America? You say you plan to bring "Premium Content" as well? May I assume that means stealing Cable signals?

If you are so certain your current creation has merit in the 'real world' I suggest you offer copies to us for testing and our review. If you sent one to me, I would NOT do a side-by-side comparison, I would do a same-place (location) compared to known working antennas: directly compared.

I am not the only Member here who does extensive antenna testing and antenna building. If yours is a Turkey, we will say so, BUT if it works, most of us would very likely buy our own green dishes and promote them!

None of us on this Forum have a dog in this fight, but if you are going to claim your antenna is a 'revolution' in receiving FREE OTA I would think you would be interested in (free) independent testing and IF your antenna proves to be fantastic, our positive reviews here would go a long, long way toward your antenna sales.

For now, the math (size) does not work for any of us. Please advise if you want us to consider testing for you. TRUTH OR DARE.

No kidding! This looks like it's straight out of the ad pages of popular science. Remember that "dish" antenna?
