Here is the link to the Antenna specs for all the models. You can analyze as much as you dersire.


The vhf hi gain is red zone (3-5 db) much less than the ya1713

uhf gains are in the ball park for the higher gain uhf antennas in the market.

GAIN for the extreme fringe 66"
db over reference dipole/front to back ratio
CH-7 3db/13.1
CH-10 3.4db/9.6
CH-13 4.8/6.8
CH-14 10.4/25
CH-27 12.2/22
CH-39 14.5/21.5
CH-51 12.9/20

These are the mfg's measurements...measurements from a test range are coming according to the pdf.

average gain for comparison
this one
vhf hi 4.1 db
uhf 12.5 db

vhf hi 11.5 db
uhf 13.275 db

come on people...wouldn't you think a reputable company would publish test range figures first instead of their own????

Send me one so I can test it and make up some numbers for ya all.

While I agree it is noble to want to support American manufacturing, this seems like a similar situation to the auto industry: The Japanese made (make) a superior product for the same or less money - it's really a no-brainer. (As Rick0275's data establishes.)

The truth is it's a combination of corporate greed and union strong-arming that's been the downfall of American manufacturing, nothing more.

And the proof is in the fact that the Japanese mfgr's now have plants located here, and are still able to hold the price line while maintaining the same quality mark.

And lets not argue the point that "They're only assembled here" - when I looked at the 1st generation Ford Fusion it had 88% foreign content! (Mostly from Mexico)

Bottom line is, if you produce a superior product you can charge the same, or more than your competitors - and expect to be successful.

It's called free enterprise...

OK. Rick0725 already posted most of the relevant specs, but here's some more info taken directly from the patent application.

Their own numbers (Table 1) clearly show that these antennas are NOT good for VHF. Out of all their antennas (DUV-U, -UC, -M, -MC, and -F), their VHF gain numbers range from -8.52 to 0 dB. This means that almost all of their antennas perform worse than a simple dipole at VHF frequencies. I would NOT classify these antennas as UHF/VHF combo antennas.

The same table shows UHF gain in the range of 5.5 to 11.57 dB, so these DO have some UHF gain, but they are average performing antennas, which is about what you'd expect from antennas this size. For deep fringe situations, you would probably want to go with a larger antenna with even higher gain (like 13-16 dB).

Table 2 shows gain (average of VHF-Hi and UHF gain in dB) divided by weight (in kg), which is a rather meaningless benchmark. Some antennas in the comparison include plastic housing to give them better durability (protection from wind, snow, sun, etc.), yet none of that gets reflected in this made-up benchmark.

To really shine at this, all you would need is two very basic Yagi antennas (one for VHF and one for UHF) and a UVSJ to combine them. This would give you medium gain in an ultra lightweight setup that would blow away any of the antennas in this comparison.

This table is somewhat related to some important issues, but does not directly address things like:

- Wind resistance (how much strain is put on the mounting system)
- Snow/ice loading (some structures do better than others)
- Shipping/installation dimensions and weight (weight matters, but it is not the only thing)
- Sturdiness/quality of construction/longevity
- Aesthetics (something with a small visual cross-section might be desirable)

Given the information in the table, there's no way to tell if the Digitenna products will fare better or worse than the other products in any of these areas.

It's also interesting to note that all the antennas selected for comparison had no VHF performance to speak of. The complete list of antennas compared include:

Winegard "Square Shooter" SS-1000 (short range UHF antenna)
Antennacraft HDX1000 (short range amplified antenna)
Winegard PR9018 (a UHF-only Yagi)
Channel Master 4221 (UHF-only 4-bay bowtie)
Channel Master 4228 (UHF-only 8-bay bowtie)

Notably missing from the list are any of the true UHF/VHF combo antennas (with positive VHF gain figures) from Winegard, Channel Master, Antennacraft, Radio Shack, or anyone else.

It's sad to see our patent system abused with this kind of marketing crap.

[/QUOTE] You only referred to antenna area and the narrow band efficiency, not the broadband efficiency of reception for that antenna area.

Please review and comment on the broadband efficiency from the objective measurements cited.[/QUOTE]

What the HELL are you talking about? The stuff is STILL vastly overpriced. I wouldn't pay more for a Buick than a Lexus because the Buick was made here and the Lexus wasn't. I don't mind paying for quality, but I absolutely refuse to pay through the nose for hyperbole.

I have 2 Digitenna the duv-fringe and the duv-deep fringe I payed to have them installed within 3 months the rear elements blew off . They are very cheeply made, way over priced at 190.00 and 220.00 and do not do what they claim they will. And if you call the company direct they blow you off and will not talk to you because your not a dealer. I'm now removing them after 10 months and replacing them with Channel Master like I had before.

XG 91 - lifetime warranty.

Winegard 8200U - lifetime warranty. It breaks, call them and unless you blow out the transformer - they will give you what ever you need to get it up and running again.

Very nice people to deal with.

Default Digitenna Max

I have heard it is back in stock. Is it worth buying this kind of things?

It depends upon what channels you want to receive at your particular location.
