TV or Television is a common sight in most of the homes. But the way they perceive it and watch programs and shows differ. Cables were a common sight until DTH technology came into thepicture. Even today, cables are persistent in many parts than DTH due to many factors. While others rely on Antennas or Satellites dishes(DTH) for their entertainment needs.
Antennas and satellites TV aerial repair services dishes work a little differently. Antennas pick up radio waves that are broadcasted by TV stations. The types of waves that can be received and at what distance they work, all depends on the type os Antenna you choose.
Satellite dishes as the name says receives signals from the satellites and broadcasts them to TV. This is said in a very simple manner, while the whole process is a longer one in actuality. Well, be it antenna or a dish, what should you be aware of before buying them? Here is the guide:
Check if it's Free or Subscribed?
The antenna can pick up all programs for ‘free’. Yes, but that has a limitation to the number of channels available. This is sometimes referred as ‘OTA’ meaning Over-the-air television.
On the other hand, satellite TV’s or dishes needs a monthly or annual subscription fee to bepaid by the consumer. Thinking if you can receive these signals using your antenna? That’s not possible! The signals are encrypted and a device to decode them is required which is present in the set-top box.
Many satellite dishes company have packages for both TV and the internet. They have high-speed internet offered by a router, along with the digital TV services. These companies buy premium packages from the network companies and give away quality signals and high-speed internet to the customers.
There is something called as ‘Free to Air’, which means anybody having a satellite dish can receive few broadcasts without any payment, just for free.
Check for Signal Types:
The signals received by dishes are those that are sent by satellites back to the earth. The satellite dish can only receive the signal and do nothing else. The whole job of decoding it depends on the DTH receivers placed inside the box.
The Antennas can receive 2 types of signals, which are local ones.
Check for Installation Procedures:
The installation of a satellite dish or an Antenna is definitely a cumbersome job. Sometimes the dishes are too large to be handled manually, and it’s always better to let the professionals do the job.
Once you subscribe to a satellite TV, the company will send people to do the task, may be for free, or sometimes for a fee. An LNB is a device that is mounted on the satellite dishes, to reduce the noises. No matter who installs the device, professional or a novice you, but the quality of the experience depends upon the co-axial cable, and it’s important to get the best brand of cables. The best co-axial cables come shielded, protecting from signal leaks and offer a great lifespan.
In case you do the installation, be sure to follow strict safety measures.
Check for the placement and positioning:
Antennas are mostly mounted indoors, only a few of them are mounted outdoors. But, satellite dishes are always mounted outdoors. Antennas are available in avariety of sizes; older ones are called rabbit ears, while the newer ones are large and multidirectional. The antennas are mostly horizontally polarised, placed on the rooftop. The satellite dish also uses this polarisation technique to double the capacity of channels received over a fixed frequency.
Check for your System Requirements:
To enable programming, the receiver must decode the sent encrypted signal. The device decrypts the scrambled signal and returns it as audio and video fragments to be telecasted on TV. Using satellite dish, you will get the device along.
But, in case you are using the antenna, or old TV (analog format), you will need a digital converter box.
Check for the costs:
Costs of antennas and satellite dishes vary largely, due to the type of transmission they do, quality of work. The simple antennas which come with a limited number of channels are on one side of the spectrum while the DTH satellite dishes are on the other end. So, the more channels and quality of signal you need, more the money to be shelled out.
But with technology, the DTH services are turning out to be better than earlier and they are affordable. There are packages that you can choose from paying to only channels that you might watch.
Check for Signal Quality:
Though you use antenna or DTH, your signal quality is sure to be affected by many factors. For satellite TV’s, theweather is the biggest spoiling force. If there is huge wind or heavy rainfall, blank goes the TV. Even if the rainfall is less withjustthe breeze, signals are interrupted. Apart from this, satellite tvdoesn't have amajor drawback.
While antennas have positioning problem, you need to keep changing the position every time there is abreeze, cos they pick up signals from air, for free.
Based on your requirement and comfortability choose the ones that fantasy you.
