With an outdoor antenna you can watch HDTV for free of cost. All you
need is a high definition television or an HDTV-ready television. If you
have a HDTV-ready TV then you might need high-def tuners such as Humax
HRA100. These are high def tuners that will enable you to watch HDTV for
free. This tuner can receive broadcasts that are high-def.
You
need an antenna that can be installed outdoor which is connected to your
HDTV or the high-def tuner. If you are close to the tower that
broadcasts high-def signals then you can use indoor antennas also. The
HDTV signals are considered as line-of-sight signals and hence you get a
better reception of the HDTV signals if your antenna is in line with
the tower that broadcasts the HDTV signal. For this purpose it is better
to install your antenna in the roof of your house.
Some of the
tools and the accessories that you need to install the HDTV antenna in
your roof and then to connect it to the HDTV or the high-def tuners are,
Mounting hardware, wrench, drill, screwdriver, grounding wire (the
length should be sufficient to run from the antenna to the ground),
grounding strap, coax grounding block, and a shielded 72 ohm coaxial
cable (all weather). The length of the coaxial cable will depend on the
distance from the antenna and the place where you have your HDTV or the
high-def tuner. A short cable to connect to the TV and the dwelling
where you bring the cable from the antenna is needed. With these tools
and accessories you can connect your HDTV to the antenna on the roof top
of your house.
If you are planning to buy an HDTV antenna there
are many models available in the market. You have the choice of choosing
the right model according to the budget you have. If you need any
assistance to choose the right antenna there are websites for that
purpose. A simple search in a search engine would give you lots of tips
on that topic. These websites have an easy to use interface that enables
you to key in your address and then they give you the choice of the
HDTV antenna that might suit your location. They decide on the choice by
considering the tower that broadcasts HDTV signals to your location.
The distance of the tower plays a role in the choice of the antenna. It
is better to choose one that is certified by Consumer Electronics
Association (CEA). The most popular are the ones that have multi-element
in them. With multiple elements the ghost images are reduced
drastically.
While installing your HDTV antenna on the roof top it
is better to have an assembly that can be moved easily. You should also
be able to rotate the antenna to adjust the direction of the elements
so that they are in line with the broadcasting tower. If you have two or
more broadcasting towers within a short angle of the placement of your
antenna, then you can use devices like 'antenna rotator' to select the
best tower from which you receive the HDTV signal. After you place the
antenna make sure that you are connecting the antenna and the HDTV with
the coaxial cable. Make sure that there are no metallic objects near the
antenna. Metallic objects interfere with the way the antenna functions.
