New Digital Aerial Chelmsford

I thought I would write a few paragraphs for a new digital aerial Chelmsford giving some free info and pointers for those seeking a new digital aerial.

The cost of the new digital aerial installation can vary considerably, dependent on the parts required, by the property.  Signal strength, and quality, in the property’s location is also another factor.  Choosing a new digital aerial should be made by an experienced aerial engineer who knows the area well.  A lot of aerial companies like to advertise locally (Chelmsford) but are based in other counties and do NOT know the area or the black spots.  So ensure the company of your choice is loacal.

Chimney brackets and wall brackets should be galvanized to ensure a long life, which Andy’s Aerials always use.  Other companies cut costs by using non galvanized cradles & brackets (some even Painted)!  Either make more profit, or sadly do a cheaper job and quote cheaper.  Most properties now suffer with 4g overpowering signals which need to be blocked.  In the not too distant future we all will need to attenuate or block the new 5g signal which is going to affect our TV viewing again, because 5g will be transmitted at 700mhz.

Amplification:  Because a lot of properties in Chelmsford will need an amp to lift the digital signal to the required level.  To be able to receive the perfect functioning picture we require is mathmatics, the amp adds to the figurs.  Not all properties need amplification, which is another cost factor, if an amp is required.  Time is another, some properties are easy to install a new digital aerial to, and run new cables.  And others are challenging and time consuming, with greater risks, which again will add to the cost of the new digital aerial installation.

 

A new digital aerial installation should last years if installed by a diligent aerial engineer, who takes a pride in their work, and is not happy cutting corners.  We believe quality parts should be used as cheap parts doe not last.

There is a huge range of aerials, amps, and cable to choose from.  An experienced engineer will know which amp is best suited, to the property for the signal strength and quality.  Measuring the incoming signal strength is essential.  Thye will also be able to deal with the incoming and unwanted 4G signal which can be seen on their meter.

New cable runs should be run discreetly, as no one wants to see an aerial cable, Andy’s Aerials always try to run our cables as discreetly as possible, in some cases completely invisible.

Pointer for choosing an engineer:

  • Local established company knowing the local area
  • Quality parts, galvanized brackets and generous gauge aluminum masts
  • Neat tidy, caring company with proven history
  • Spectrum analyzer, to see issues with signal (not hand held strength meter)
  • Written guarantee
  • An engineer, who you are happy to engage

Digital Aerial Repair Chelmsford

 

Why do we need a digital aerial repair Chelmsford?  Or a digital aerial replacement?

We are often asked by customers why their digital aerial is in need of repair or replacement; we very often hear the sentence; “it was working perfectly yesterday”.  Digital outdoor aerials withstand the elements, in the summer & winter.   They are baked throught the summer, and in the winter they are frozen, and get wet when it rains.  When the temperatures rise in our fantastic summer months, the roofs of houses/buildings absorb the heat , and aerial or satellite cables also absorb the sun’s heat.  The sun’s uv A’s B’s & C’s gradually decay the aerial and satellite cables, causing them to split and crack, making the original waterproofing non-existent.

The cable deterioration is pretty much like EVERYTHING else in life, it has a life expectancy, best guess:  20 to 25years.  Once rain water has entered the cable it can only run down.  Aerials are generally mounted on the chimney stack on top of a house;(for best signal quality)  gravity ensures the water in the cable travels down.

The water can arrive at a filter, masthead pre-amp, distribution amplifier or straight to the TV direct.  Any scenario is not good with electrical supplied devices and water.

Some digital aerials, have a plastic cap on the dipole of the aerial,  where the aerial coaxial cable joins to the digital aerial.  This cap is also baked in the sun, soaked in the rain and frozen in the cold winter months.  As you can now guess an aerial with a broken cap, mounted on the top of a building, can only capture water as and when it rains.  Again with gravity, the water makes it way down the cable to the bottom, causing customers to call for a digital aerial repair Chelmsford.

In days gone by, VCR’s (Videos) would receive the aerial coax cable before the TV and was much cheaper to replace than a TV.

I have been called out to replace an aerial where the customer had tied the aerial cable up in the air, slit the cable with a knife, and placed a cup under it to collect the water!

Today’s digital signal pixelates luckily, and customers call us to investigate the cause at an early stage.  A lot of other aerial companies will replace an aerial, and either they are too lazy to replace the cable, or have simply not charged for it in the aerial installation cost.   Cheap, you only get what you pay for.

So you can now have a brand new aerial connected to a 20year old cable!  It does not matter how good the new aerial is, if the signal cannot reach the TV, you will not receive pictures
