Product Description

Product Description

Receive crystal clear pictures on every channel with the Zenith ZHDTV1 HDTV indoor antenna. Truly the only HDTV antenna, this highly directional UHF antenna features a narrow acceptance angle and high front-to-back ratios to reject unwanted multipath sign

From the Manufacturer

NOTE: Please note that the newest version of this antenna is the Philips PHDTV1 Digital HDTV-UHF Indoor Antenna.

  • Highly Directional--High front-to-back ratio helps reject unwanted multi-path signal corruption. This ensures densely populated urban areas receive clear HDTV and data broadcasting signals.
  • Even Response--A flat forward gain slope delivers balanced reception throughout UHF. Ensures all channels are received to the same quality.
  • Proven in the Field--This antennea has proven itself in front of the FCC, and is now the "reference antenna" for data broadcasting.
  • Easy to install
  • 75 Ohm, gold-plated "F" connector for antenna inputs
  • Note: When using the enclosed antenna, you will only receive UHF channels. To receive VHF channels (Channels numbered 1 thru 13), you must also connect a VHF antenna to the TV. You can install a device referred to as a "antenna combiner" which will combine the two antenna output signals into one 75 ohms for a single connection.
  • Dimensions (H x W x D): 9.5" x 13" x 13.5"

I live in a historic brick building, which means I cannot get cable or install a satellite TV antenna outside. As a result, my reception has been horrible, which is a pity considering my nice HDTV. I have been using a Terk TV55 indoors with limited success (I constantly have to reorient it in order to find the "sweet spot" to receive digital and hdtv channels).
This antenna is a dream come true. Small, light, easily moved, the reception of this small un-amplified antenna is FAR better than that of the Terk one I upgraded from (and a fraction of the cost, I might add). Considering the poor reception I had before, I am greatly impressed with the ability of this small antenna to overcome the thick brick walls in my building without the constant loss of signal that the Terk antenna had.
Fantastic! This is the third HDTV antenna I've tried and so far, it is the best I've ever seen. I should reiterate that this antenna is un-amplified, which means that unlike other HDTV antennas, you don't have to plug it into an outlet.
One caveat though: the antenna is not exactly rugged. One of my friend dropped it on the floor and it broke the connection to the back, requiring me to order a new one.

This is an excellent indoor antenna, I haven't found better! Great picture quality, very low multipath, high gain for long range. If you wish to use an indoor antenna for whatever reason (in my case, I don't feel like the hassle or expense of installing an outdoor antenna yet, I probably will one of these days). There are a few things any potential buyer should note:
1. This antenna is marketed as an HDTV antenna. And, yes, it will receive ATSC (American HDTV) signals. No, a special antenna isn't necessary to do this. This antenna is actually made by a British company (Antiference) where they have a totally different digital TV system (DVB-T, which is debatably significantly better in terms of reception ease). I'm sure this is a great indoor antenna for HDTV - but the same characteristics of a great UHF antenna, make it a great antenna for any UHF signal, be it ATSC (American HDTV), NTSC (American analog), PAL, or DVB-T. No special antenna required. Though ATSC is so hard to receive with multipath, a GOOD antenna is important (which this is for an indoor).
2. Even the best indoor antenna simply will not compete with even a decent outdoor antenna. Outdoor antennas are able to use bigger, more effective designs and even more importantly they have a clear line of sight. An good outdoor antenna is best, this is merely a good 2nd place.
3. This antenna is UHF only. In case you're not aware, that means this antenna will not recieve channels 1-13 (VHF-Lo, and VHF-Hi). Well, actually, it will, but VERY poorly. This isn't a problem with this antenna. It's a UHF log-periodic design. It's a wonderful UHF design. It simply isn't made to pickup VHF.

After many attempts to find an antenna that would provide a consistent signal for my 5 local HDTV over-the-air broadcasts...the search is over! This is the one!
I live about 40-50 miles away from the broadcast towers in the middle of the woods (4 acres). Previously I purchased a Channel Master 4-bay UHF antenna. This was big, bulky and very ugly...not to mention dangerous to handle due to all the sharp wire ends. The [costly] Channel Master 4-bay antenna picked up less (inside my house) than a pair of rabbit ears with an adjustable UHF loop...which at least picked up 3 channels (1000 kw power stations) without much problem. The rabbit ears and loop needed to be constantly adjusted to keep the signals in over the course of several hours. This ZHDTV1 instantly gave me 5 channels and held the signal strength for many hours without needing to be adjusted. Once it is pointed...IT WORKS!
I also love the simple design. It took 5 seconds to put the pieces together. The coax cable attached to it is removable...which means I have the option to upgrade the cable to a higher-quality one and/or a different color that better matches my decor.
My only beef is that it is too light and thus can be easily tipped over or knocked off whatever it is resting on. A weighted base would be a welcome design improvement. A small piece of Velcro on the bottom of the base might work.

One last note, I do have it connected to a small external amplifier.
Believe the reviews...this antenna is sweet. Watching Jay Leno on the Tonight Show in 1080i HD is something that just can't be have to experience it for yourself.

If you read the reviews, some people pan this, and say it won't even get what rabbit ears get. They are correct. Others rave about how well it brings in signals compared to even expensive antennas. They are correct too.

What you need to keep in mind is that some HDTV signals are on UHF and others are on VHF. The manufacturer calls this an HDTV-UHF antenna, not an HDTV/UHF as Amazon had it listed when many of the reviews, including this one, were originally written.

Rabbit ears work on VHF and not UHF, so it's not surprising that they get some channels better than this -- it's not designed for VHF. On the other hand, this antenna does a great job on UHF, so HDTV signals there will come in clearly.

Before you get it, check to see where your stations really are on the spectrum. Keep in mind that they may move once analog goes away, and that they may have an alias. (i.e. what appears to be channel 7 might really be 52.1 even though your TV says 7.1, and they may plan to move back to channel 7 in the future when the analog channel 7 is gone.)

Keep in mind that most HDTV channels are on UHF, so in some parts of the country this will work perfectly. But if you get some channels great and others not at all, you might be missing those stations that are really on channel 13 or below.

Other similarly designed antennas will have the same problem, so go by what the manufacturer says, not necessarily what the listing says.

I give it 3 stars in terms of being an HDTV antenna and 5 stars as a UHF only HDTV antenna.
