DTH signal loss during rainy season and in bad weather conditions is a common problem now; we can take some precautions to fix the signal problem issue in direct to home services.
DTH services using Ku-band transmission has a lot of benefits. The main advantage is that we need small size satellite dish for reception.
Major disadvantage for c band satellite reception is the big sized dish. Ku-band dish doesn’t require much space; we can easily install it on our home roof. Ku- band satellite reception has several disadvantages too. The main issue is the signal drop which occurs during the rainy season. However, we can take some precautions to prevent DTH signal loss during rain.
During the installation, ensure that every transponders get the maximum signals. There are a lot of transponders in DTH service; you are getting channels from these. During the installation process, you should ask the technician to check signal strength for all transponders. We can prevent DTH signal loss during rain with this step. Though signal strength may be down, we will get channels if we follow this step. If you have already installed DTH system, check your signal strength.
- Checking signal strength can be done through menu, find set up or installation (the term will different in some set top boxes). If you have seen any drop in signals, fix it. You can do it yourself if have interest or call for help from experts.
- Cable quality: Ensure that there are no joints between the connection cables, means between lnb and set top box. If there are some joints, you will have low signal strength. Use only good quality cables for DTH connections. This is another reason for DTH signal loss during rain and bad weather situations. We are using a device named lnb to receive signals.
- Lnb refers to low noise block. Ensure that you are using a good quality item. 0.03 dB or 0.05 dB lnb’s are being used in Indian DTH services.
These type of lnb’s are not good for rainy conditions. You can check for 0.01 dB gain lnb’s which are available through online purchase. DTH signal loss during rainy season can be easily tackled by following these solutions.
Cover LBB with transparent materials
Another idea is to cover low noise block with thin plastic or any other materials to prevent rain drops. Make sure that you are using transparent materials for covering lnb. Empty bottle of 2 litre soft drinks is ideal for this. Cut the neck part and cover lnb using this. You should cover it slowly, otherwise it may affect the dish alignment.
Please note – Results may vary from person to person, it depends on your ability to align dish and lnb properly for maximum signal strength.
