can this be adapted to the new signal or do I still have to buy a converter box?
I did notice on the site that they had what looked like the same antenna with a small device in the center that is labeled DTV ready.but I have no way of knowing what it does?

There are no such thing as DTV antennas, it is just marketing, just like "color antennas" of the 70s..... It is just an RF antenna optimized for the newer channel range (commonly, channel 7-51).. You may have stations switching from UHF with the DB4 is best at to VHF after the transition, but wait and see how it works, it may be fine or an addition VHF antenna may be needed...

The DB4 is a UHF antenna. As posted, the antenna does not care if the signal is NTSC analog or ATSC 8-VSB modulated digital. The DB4 may pick up stations physically broadcasting on upper VHF if the signal is strong enough. The question is whether all of your stations are currently digitally broadcasting on UHF and whether any will move to upper VHF 7-13 or even low VHF 2-6 after midnight, February 17. If you could post your zip code, we could look your local stations up. Or you could check the station's transition plans at http://www.rabbitears.info/ or Falcon_77's spreadsheet at http://www.rabbitears.info/ss/.

Digital TV signals/tuners are far more subject to interference due to multipath reception problems and so new antennas have been developed that are far more directional and therfore subject to less multipath interference. These new antennas are called digital antennas and of course can also receive analog signals without problems

You of course need an ATSC tuner if you don't have one already to tuner digital OTA.

My zip is 72227 little rock ar
digital channels will be 5-49 just using whole numbers
32 is 32.3 that type of thing.

When I looked at my antenna I thought ok I need converter box. No problem.
then looking at their site they have same antenna with a black whatever put in the middle of the antenna and called it digital ready.

Was not sure if this was some type of converter or what.
thank you for clearing that up for me.

I read the reviews on the converter boxes and most don't sound too good.

I belive RCA was ranked #1 in pic quality. Motorola was way down the list.

Have not seen any reviews on the newer ones from people like apex that was on sale last week at BB I believe.

etrin,
I suggest that you get the CECB box and try using it with your current antena now before you get a new one assuming that your current antenna supports both VHF and UHF channels

Go to the CECB sub-forum for recommendations on the converter box. The Zenith DTT901 works very well.

You have 1 digital station on low VHF, KETS-DT PBS 2 on VHF 5. However, KETS-DT will be moving it's physical RF channel to VHF 7 and, according to Falcon's spreadsheet, KETS-DT is shutting down the VHF 5 broadcast in mid-January. Your post-transition channels include VHF 7, 12, and UHF. If your current antenna gets the analog VHF and UHF stations ok, try it with the converter box. Don't spend money on a "digital" antenna unless you find you need a better antenna with more gain.

I have the Antennas Direct C4. The black box in the middle is just a balun (transformer) to provide 75 ohm output for coaxial cable. I'm currently testing it in my living room prior to mounting it in my attic. It does appear to be highly directional in the high VHF band. It remains to be seen whether I can get away without a rotor at a location where one station is 30 degrees away from most of the other stations.
