1. Digital TV is a relatively new technology and many
people are still confused about the whole thing -
what it is, what it involves, its advantages and its
disadvantages. One point of confusion is the digital
TV antenna.
dipole antennas
2. For those not in the know, digital TV antennas which have been
specifically designed for the reception of digital TV are non-existent Truth
is, the same TV antenna which are being used for the older analog TVs
are the same antennas used These antennas are usually UHF/VHB
capable which are also capable of receiving radio broadcasts
3. One major requirement is that this antenna can operate with the different
broadcast channels Basically there are the indoor and the outdoor
antennas and the outdoor is further subdivided into the grouped and the
wideband The grouped are tuned to cover only some parts of the UHF or
the VHF bands
4. With the group more than one antenna would be needed to get the full
range of the broadcasts in the locality These also offer better reception
compared to the wideband which are multi-directional antennas The
bow-tie antenna is one example of the wideband and this is the best type
to use for long range reception
5. Indoor antennas are more susceptible to unstable reception This can
get affected by moving vehicles and the shadows and glares which they
can cast The indoor antennas will also react to trains and airplanes
6. This is why most would recommend the outdoor for it is more stable
dipole antennas Outdoor antennas get better signals, true, but they can
also get obstructed by mountains, hills, trees and tall buildings
7. This is the reason why these antennas are usually placed on high
ground where there is less obstruction for this way it can get the signal in
a straight line It is also important to only get the good quality antenna
made from materials which are more durable for they are exposed to the
elements all the time
8. Maintenance can be an issue especially in wooded areas where leaves
can cause obstruction to the signal
