Rabbit Ears To Stage a Comeback Thanks To DTV

Jeffrey Breen writes "Like Monty Python's Killer Rabbit, cheap indoor antennas seem harmless to satellite and cable providers. But with the digital TV transition in the US, rabbit ears can suddenly provide digital-perfect pictures, many more channels, and even on-screen program guides. Already feeling pressure as suddenly budget-conscious consumers shed premium channels, providers must now get creative to protect their low-end as well."

    Rabbit ears don't pick up UHF signals; they are for VHF which is going away. It's the "loop" part of current antennas which will receive UHF.

      Bunny ears worked for my converter box. 11 channels, all with excellent quality. Frankly I was astonished, you NEVER got quality like that with analog VHF/UHF, and I wasn't expecting much. I just bought the converter box recently as a 'just in case' measure. We have Comcast here, and ever since they laid Insight to rest, multiple-week-long waiting lines for service have become a reality. When you live in an area known for rough weather, that's not good.

      That said, a proper antenna - combo VHF/UFH - would probably work even better, but this stuff will work satisfactorily with bunny ears, which are themselves not much better than a coat hanger or a paper-clip.

      A one-inch piece of wire or a dampened finger will "pick up" UHF, VHF, or Martian signals. It's all a matter of how well, not whether or not they do.

      The "loop" is nominally designed-for and tuned to pick-up UHF signals. The "rabbit ears" is designed-for and tuned (by varying the length of the ears) to pick-up VHF signals. But either will "pick up" both bands with some degree of success. ("Both" bands is actually a misnomer, since the VHF broadcast TV allocations span multiple ranges with holes for other services, such as public safety, etc.)

      Given that almost nobody bothers to tune rabbit-ears by adjusting their length, the non-adjustability of loop antennas, and the incredible width of the broadcast TV spectrum, most simple indoor antennas like this are essentially "random wire" antennas for most channels anyway.

      Nope. ALL TV broadcasters have the option of continuing to use their newly alloted UHF channel, or keeping their old (sometimes VHF, sometimes UHF) channel. In either case, they had to notify the FCC long ago. There is no special requirement either way.

      Most are just going to stick with their UHF allotments and let the VHF go dark.

      Also no. Outside of Alaska, just about all broadcasters with an analog channel on VHF-lo (2-6) are jumping to UHF. Just about all broadcasters that had a VHF-hi allotment (7-13) wish to continue using their VHF station.

      Fortunately, VHF-hi is close to the low-end of UHF, and the old UHF loop antennas work surprisingly well for it (better than rabbit ears in my own tests). Yagi/Corner-reflectors don't work all that well, but other outdoor UHF antenna types have at least decent gain on VHF-hi. That, combined with the switch to digital means I wouldn't worry about it much.

      Anyway you need a 25 foot or higher antenna. Rabbit ears/loops don't cut it here in "rural" Lancaster PA.

      Lancaster, eh? That's Amish country, right? Did anyone mention that the rabbit ears TVs require don't really come off of rabbits? They're telescoping metal tube thingies.

      You may want to move to San Francisco. I used to get some 20 channels here (some well, some not so well, but could be improved by moving the antenna) just on rabbit ears. I've tried a couple or three converter boxes. So far, the Zenith DTT901 works the best. I got more like 50 channels (including the .1, .2, etc. channels), all as good as any cable I've ever seen, with that box and the same rabbit ears.

      I was told by someone in the industry that Zenith made the original encoders and have the license for the technology, so they do a pretty good job.

      Also, according to a Consumer Reports comparison chart, only Zenith and one other (four-letters in the name) have a very full set of features. Apparently the FCC did something with the requirements for the boxes that can be bought with the coupon. They specified a minimum set of features that a box must have to qualify for a coupon purchase. They also defined some optional features. But any features beyond those listed make the box not qualify for purchase with the coupon.

      At least make sure your box has the "zoom" feature. Otherwise you're stuck with whatever default format the station puts out. With zoom, you can, in many cases, select letterbox, sidebars, or full-screen if the provider makes those options available.

      Also, especially with the delay in implementation (though most stations seem to be making the switch as early as possible), you may want to be sure to get a box with analog pass-through. What that means is that urning the box off allows you to still see any analog stations you may like, but which are waiting until the last day to switch. It also allows you to see low power stations which remain, as well as possibly any analog tv transmitted by amateur radio operators if that is an issue for you.

      1) Don't discount the possibility your DTV converter box is a piece of junk. avsforum.com has a wealth of DTV information.

      2) You need to hit tvfool.com or antennaweb.com and figure out your distances to the transmitting towers and the orientation to your home. They also give approximate dB strengths. If you can get better than -47dB on a signal, you'll probably get DTV. (That's my observed signal threshold where I live in the Bronx. That's not based on direct instrument readings.) Then see what kind of signal strength you can get with your antenna and pre-amplifier setup.

      3) Generally, if you're within 100 miles and have a clear LOS to the tower, you should receive DTV by the time the cutover occurs in June. Before then, stations will skimp on the transmission power. What I'm trying to say is that DTV will suck now because there's no cutover mandate. You won't know for sure what you can get until after June.

    In the US the major network affiliates generally broadcast on VHF frequencies, for which these rabbit ears are sufficient. In the UK we use UHF, which doesn't perform as well without a dedicated external or loft aerial.

    The UK used to use VHF for television, back in the days of the 405-line black & white service. BBC1 was broadcast on VHF Band I, whilst ITV was on VHF Band III. You can still see some of these aerials on the tops of some buildings; they were needed as the UK transmitters were often many miles away, although it was possible to pick up some services on an indoor aerial. These transmitters were eventually switched off in 1985.
