Digital TV Aerial Or Antenna Installation For Scratch Free Pictures

Facebooktwitterredditpinterestlinkedinmail

This is how to install your Antenna/Aerial for the best signal reception. In this article I will interchangeably use the words antenna ans aerial. I mean the same thing.

The digital migration in Kenya and other countries around the world is complete. As of right now there are no analog TV broadcasts anywhere in the world. The migration in Kenya was done under the mandate of the Communications Authority of Kenya, CAK.

This post is about how to install your aerial professionally to get good quality Digital TV with scratch free pictures during any weather condition. This information will come in handy for anyone struggling with weak signals.

Antenna Installation Tips

  • First never mount an aerial on a wooden pole. The technically correct way is to mount it on a metallic pole, the best type being aluminum for the obvious reason that aluminum does not rust. By the way this is the same material used to make your aerial. Its very important that pole should also have a circular cross section like the featured image.
  • Secondly the antenna must be fixed tightly on the pole to avoid play. A well installed aerial should not sway in the wind at all. Fix this whole system on a wall roof or whichever appropriate place and make sure there’s no play too. In fact if a crow should land and take off from your antenna without shaking the aerial at all. Sudden aerial movements are what actually cause pixelation or scratches to appear.
  • If the system is steady then you should get a qualified technician to ground the antenna pole to your supply ground terminal. This prevents lightning from damaging your decoder or expensive digital TV in case lightning strikes your antenna.
  • Very important don’t use a white coaxial cable, this type of cable gets damaged quickly by weather elements. Use a black cable instead; it withstands harsh weather conditions for a long time.

No Joints

  • Also very important the cable must run uncut from the antenna to the decoder. The best cable to buy is the Black in colour ASTEL or JACOBS Coaxial cable; it may be expensive but totally worth it during the long run. Do not do those juakali connections with insulating tape or in extreme cases cello-tape and nylon paper. These joints take away a percentage of the overall signal quality.
  • Use the correct length of cable, it should not be rolled inside your house or ceiling. Cut the excess cable so that your decoder or digital TV will receive the maximum signal it should receive.

I have seen some antennas like the Mesh Jetta Antenna being sold with a very thin white coaxial cable. This antenna is good but the cable is of very low quality replace it immediately with an Astel or Jacobs black in colour cable like I mentioned above.

  • Weather proof your connections at the antenna by using silicon or tar (the stuff used to seal leaking iron sheet roofs). This keeps away moisture and spiders from your terminals giving you constant signal strengths during any weather.

Weather Proofing

I prefer to use Sparko High Tech Black RTV Silicon. Its used for gasket making and as an adhesive sealant in motor vehicles. It is easy to apply and cures fully in 24 hours and if applied properly to clean surfaces, it creates an air and water tight connection. To make the whole system better install it in such a way that you can rotate the aerial freely on its axis. This enables you to lock on the strongest signal level easily.

Now you can enjoy the best Digital TV signal right in your living room or Bar or Club.

  1. I have a problem in Kahawa..So many scratches on TV.. I suspect the signal is poor..Which is the best aerial to go for?

    1. Get the Ellies mesh type of antenna, it goes for about Ksh1000 and if combined with an Astel coaxial cable it will get rid of all scratches. Alternatively you can also buy the Jeta antenna but replace the cable and use everything supplied in the package.

          1. Can you recommend a technician who can follow these standards (in South c area)?

  2. hi. I have a sony digital tv (model no. KDL32CX520), but I can not receive any digital signal. I stay in Nairobi eastleigh area. I even recently bought a new aerial and coaxial cable but whenever I such for stations I cannot receive a single channel. however I was able to receive many channels using a friends bamba tv decoder on the same aerial. what could be the problem. regards, sebastian

    1. Its either one of the following problems. Your TV tuner is damaged or my biggest bet, your Sony TV is a dvbt TV and not dvbt2 which is currently what we use in Kenya.

      1. Yes it is digital, just confirmed the specs of that model on the internet

          1. thanks Dominic, I guess I just have to buy a decoder after all

  3. Where can I get a good digital signal booster in nairobi…..or the STBs dont reqiure them. I live in a fringe reception area

  4. Thanks Dominic for the educative material on Digital TV, in fact i just came to learn about this site like a day ago. There are some few tips that i would like to share for these who are having challenges like i had. I stay in a very remote area where digital tv signal is very weak and i dont believe anyone will be putting up a transmitter any sooner. The area is Magadi and we use the Nairobi frequencies 120kms away. I have tested almost all the antenna boosters and used antenna without booster and came to discover that the best antenna for a very weak signal is the Jetta, but after you replace its cable with an astel Coax-cable as you pointed out. This is because there is practically to distance between the antenna and the booster giving it a maximum amplification. Try using nippon or whichever booster and the signal strength will not be the same. Hope this will help these living in areas with very weak signal.

    1. Thanks Bernard for those great tips, its true the Jeta aerial is well constructed but the accessories that come with it especially the cable and connectors are of poor quality.

  5. Hi I’ve gone through a number of setup tips and procedures…. No one seems to have mentioned the best place to face the antenna I belive there should be a general direction like ngong hills or something of the sort.. any suggestions?

  6. Very helpfull.. I was shopping around found an ADN box (African digital network) any info about it
