Is there a difference between a analogue and digital aerial

Published on May 27, 2014 by Tony Franklin in Clearview Aerials News

I am often asked if there ti any difference between a new digital type aerial, and the old style analogue antennas. Many people think its a sales ploy but they are wrong about that.

The main changes are screening, grouping and design. Lets cover screening  first as its one of the important changes made.

Old contract analogue tv aerials had plastic caps covering the wiring. Digital aerials have f type connectors which screen the wiring. This prevent unwanted interference.

Aerial grouping is nothing new but most analogue aerials are of the wrong group to pick up the correct tv channels. The top part of the UHF band was used to transmit freeview. This has now changed to the mid section of the UHF band. The top part of the band will now be used for mobile phone data. You may have read about 4G or lte freeview interference. This will affect old type aerials more than correctly grouped digital antennas.

The last change is in the design. Digital aerials are designed for purpose. The reflector plate is designed  to stop unwanted interference from the rear of the aerial. It also improves forward gain.

This is a new type LP aerial. Its discrete and has good gain. Its been detuned to screen out 4g interference. This is one of my recent norwich aerial installations. Note the sturdy bracket and short mast. Keeps it all neat and tidy.

Norwich aerial installer view on terrace house chimneys

Published on July 1, 2011 by Tony Franklin in Clearview Aerials News

hi im tony and  i am  a Norwich aerial installer. I fit aerials to all  types of properties in Norwich , but today i would like to talk about terrace  house aerial installations in Norwich. My concerns are that some one may get hurt one day by poorly fitted aerial equipment. I  have recently been to a couple of jobs where a newly installed aerial has fell of the chimney. the first aerial was fitted with a 6 inch wall bracket which was fitted with plugs and screws. for starters you should never use this type of fixing on a Norfolk red chimney stack. these bricks are so soft that you would never get a secure fixing.  yes there is a lot more work to do it with a lashing kit, but at least it would be safe. the other problem is installers seem to be using small brackets. these will not spread the weight over the chimney stack. and combined with a overloaded mast they are certain to fail.  so if you are having a aerial installed i would insist on at least a 8 inch cradle bracket.  If your installer is fitting a mast longer than 6 foot i would recommend a 13 in bracket or a double lashing kit.

Norfolk thunder storm causes havic with tv,s

the recent thunder storm created a surge in work, with customers reporting various problems. TV system are very sensitive and can be knocked out by nearby storms. we had to replace several tv distribution amplifiers, and some skDyHboxes were also affected. it may seem a little old fashioned to turn the power off and unplug items during a storm. but this may have saved some money for many Norwich residents.
