tv transmitter

There are many places in the UK where there are more than one transmitter to point TV Aerials at in which to get a good reception and picture. Take Lancaster in the United Kingdom, here is a city where you will see some aerials pointing one way in a horizontal position and then aerials in a vertical position pointing in the opposite direction. Ever wondered why and which would be the best set up to choose? Well firstly it would be useful to discover why the aerials are pointing to two separate locations and also why some are in the vertical position and others in horizontal. The reason is that as an Aerial Fitters in Lancaster  you’d be faced with this situation is because it is possible to pick up both the main transmitter broadcast from winter hill ntv aerialsear Bolton, and also the relay transmitter just outside of Lancaster.

When digital aerials point at the main transmitter for the region they will be positioned horizontal because of the way that the digital signal is being transmitted, but when the aerials are pointing towards a relay transmitter then they will all be positioned vertical. The reasons for that are to stop a repeating of the same signals when in an area that can pick up both the main and relay transmitters. If that where to happen there would be a situation of some TV’s picking up a strong signal and others a weak one, also there would be ghosting on the screen. This still used to happen in some areas when the TV signals were broadcast in analogue not digital.

In Lancaster, depending where about in the area the aerial is situated, it can pick up a good enough signal from winter hill, which is preferable than the relay because it picks uTelevision Antenna Polarizationp more channel choice from the main over the relay which always broadcasts less channels.  If an aerial is required to be installed in the loft, then it would be advisable to have it pointing towards the relay transmitter because it will have a stronger and clearer signal, and loft installed aerials will always receive less of the signal than if they are mounted out side on the house.

A little bit further towards the coast in Morecambe or Heysham the signal from winter hill although further away is still stronger and an average signal strength is around 60-65db with good quality. Here it is possible to put an aerial in the loft pointing to winter hill, but it may need to be amplified if it is being split.

As stated before the way the aerial is positioned determines which signal it will pick up, since the signal broadcast is either vertical polarization or a horizontal polarization. Even if you were to point the aerial at the wrong transmitter the way the aerial is positioned will favour the other one.

Usually the only time you would call for an aerial fitter is when you’ve moved home and need to sort the aerial out or if you are experiencing a problem with your existing system. So, most people will have very little knowledge of what could be wrong if they are getting poor signal on their TV. Generally it is left the the engineer to asses what is wrong, for him to give the customer a price to either fix or repair the aerial for them then to give the go ahead to carry out either an aerial repair or a tv aerial installation as a replacement.

How would the customer know if the fitter is giving them the best advice? Well there are at least a few things that anyone can do before calling out an installer.

  • First, and it may seem too obvious but it would be to check the connection where the aerial coax cable is plugged into the TV. By checking the coax plug and making sure that it is securely fastened plus making sure that there is no corrosion or water dripping out of the end. Why? If the coax plug is no properly attached then this will give a poor connection from the aerial to the TV and it will result in a loss of signal or poor signal. Coax plug for tv aerial cable If there is signs of corrosion, oxidization, or it has water dripping out of it, then this tells you that from either the Aerial head or from somewhere along the cable water is entering in. This indicates a complete failure in the system and it cannot be repaired and must therefor be replaced. Do Not plug the coax back into the TV if this is the case. Call out an aerial installer to replace your aerial cable at the very least.
  • If all is ok with the coax plug and it shows no signs of water ingress, then the next thing to do is to see if any of your other TV’s are experiencing signal problems or picture break up. If they are not look to see if the cable is going into the same Aerial as the faulty one. If it is, then it would indicate that the problem lies with either the aerial cable or the TV itself. To eliminate the TV as having a fault you would need to plug a known working aerial into the TV that is experiencing the signal problem. If the TV works, then it points to the Aerial Cable as having a fault, but if the TV is still experiencing problems, then the signal fault is not a fault with the TV Aerial, but a failure with the tuner within the TV.

By just carrying out these few simple checks you would be able to identify in many cases whether or not you would need to call out an aerial & Satellite engineer, and it will save you the cost of a wasted call out if it turns out to be a simple problem with your connection or a fault with the TV itself.

It looks like almost everyone now wants to get their satellite TV installation done by self. Though there is nothing incorrect about taking things into your own hands to save some money, some research and a cautious approach is highly advised. That being said, self-installing satellite TV is not at all intimidating. The following tips for installing satellite TV should keep you in good stead.

Dish Positioning

The dish’s positioning is the major aspect of satellite TV installation. Sans correct positioning, your reception quality would be average at best. The focal point of the dish must be facing the orbiting satellite. Your dish TV installation manual will guide you on determining satellite direction. The information for the same must be looked up as per your location’s zip code. If you still need some help, copy what your neighbor has done with the dish.

The dish’s horizontal and azimuthal direction and the satellite’s elevation coordinate could be discovered with a compass needle’s help if needed.

Location

The satellite TV dish antenna should be installed at a place with a clear view of the sky. Obstructions such as buildings, trees, mountains, etc. coming in the way of the dish and the orbiting satellite could lead to poor communication between the two. Moreover, the dish antenna mustn’t be more than 100 feet away from the receiver.

Set Up

Make sure the mast is bolted down secure and firm. It’s extremely important that it’s plumb in any given direction. If needed, use the post or magnetic level for assistance. Post cable connection, it’s now time for some adjustments. Regardless of what you do, just do not fasten the dish down.

Signal testing is the next stage, for which you may use a signal meter that’s easily available at any electronics store. Ensure the manufacturer instructions are religiously adhered to during this stage or otherwise.sky dish

Supplementary Tools

Besides the basic tools found in homes, a few other items could come in handy too. Though the items mentioned are not imperative for a successful installation, they do make the job in hand easier. For instance, an angle finder could help with the proper aligning of equipment. Also, an adjustable wrench could assist with the large-sized bolts and nuts and negate the requirement for locating the right sized socket.

Buying Installation Tools

The tools needed for installation can be easily found at specialty online and brick-and-mortar stores. Buying online is recommended since it’s much convenient and the prices are comparatively cheaper too. However, if the hardware store is nearby and it won’t take more than an hour to have the necessary items home, then buying offline is recommended.

How to set up a Sky or Freesat Dish

The key to perfect TV reception lies in the kind of aerial that you install. This is especially true in the modern era of digital TV broadcasting. A professional aerial installer will assist you to choose the most appropriate aerial for your location. When you are searching for the right aerial installers, ensure that you select the one who offers you good customer support. The technical support crews must be experienced and preferably local. You must be careful to avoid rogue installers. Here are tips for finding the best aerial installer for your TV:

TV Installation

1. A credible aerial installer must assess your current circumstances. Many aerial installers will instantly try to sell you a new aerial. But you may own an old aerial which may be amenable to an upgrade. You need to inform the installer about your current set up and find out what options there are for upgrading. In a nutshell, you should never disregard whatever equipment you have.

2. Never base your choice of the aerial installer on their exceptionally low prices. Most likely, such installation will result in a narrow choice of channels. They will use poor quality cables and hardware which means potential problems and extra charges. It saves both time and money in the long run if the job is correctly done at the first time of asking. A credible installer will always install the proper equipment.

3. Ensure you understand fully what services you will get after the install. The TV menu you enjoy will depend on the type of aerial installation you do.

4. The aerial installer needs to have the right insurance. If you hire a rogue company, you will have to absorb the costs in case any damage is done to your property during the installation process.

5. Conduct an online research to find out if the company owns a website. Then check the web for testimonials and reviews relating to this company. Remember that even rogue companies can put up professional-looking websites. Third party testimonials will help clarify if the company enjoys customer confidence.

6. You need to satisfy yourself that the company is qualified to do the job.TV aerial installation goes beyond hardware installation-there are signal assessments and measurements that call for a knowledgeable technician. Such a person will understand the intricacies of TV signal reception. Whereas it is often advisable to choose the bigger well-known regulated companies, there are other smaller outfits that may also have aerial installation expertise. For such companies, ask them to provide credible references. If a company claims to be certified, verify this from the website of the regulating body.

7. Inquire from the installer if they will be using approved or benchmark standard products. Using substandard products will result to the aerial having a short useful life. Approved products will generally have a long, trouble-free life.

8. Ensure the company you select uses the recommended health and safety equipment when they climb on your roof. You must hire a fully trained technician or engineer who will use the right harness equipment when climbing up your roof. If they fall off, they will be putting their lives at risk and also leaving you, the paying customer, liable. Professional installers use the right safety equipment and follow the proper and recommended procedures.

9. Those technicians who come to your house to install your TV aerial need to provide proper identification. A reputable aerial installation company will have done background criminal checks on them.

10. The appropriate time required to install a TV aerial is a grey area. However, a company that completes the installation in less than one hour will must probably have rushed the job. This may point to potential problems in future and this may also mean they did not abide by the stipulated safety and health procedures. A professional installer will always take time to follow the right procedures required by their training. On average, a proper install should take around two hours. Ensure you afford them sufficient time so they do it properly the first time round.
