LOFT MOUNTING ANTENNAS
mounting tv or radio antennas in the loft can be a good option due to the degree of protection against the atmospheric conditions as snow, ice, wind, etc.
nevertheless they are subject to a number of disadvantages that must be taken into account.
let us comment different aspects related with this type of installations.
- protection against aggressive weather elements under this particular point of view it is a worthy solution.
- weather conditions in the seaside areas are really strong and damage both the antennas and their supports thus reducing the operating life of these elements.
- in some countries where these conditions are quite normal but the tv/radio signal levels are rather high, this solution is very popular.
- other times, local planning restrictions lead installers to adopt this type of mounting.
- televes aerials are made of aluminium, therefore they are immune to most of the weather strengths.
- on the other hand, the bracketry is especially treated with a so-called rpr (reactive protection coating) that increases their resistance against corrosion. no doubt that if in addition these antennas are installed in the loft, their operating life is forever.
- signal level in the antenna
anyhow, this solution is not applicable where the tv/radio signals are rather weak.
as a matter of fact, there are several factors that make not suitable this type of installation:
- the roof and its structure bring to bear an effect of tv/radio signals shielding and this might make impossible the reception of any tv/radio programme.
- this is especially important when dealing with tv digital signals.
- the cliff effect must be overcome at any time since beyond this point no picture can be seen in the tv screen.
- this is not the case as analogue signals since they deteriorate progressively but maintaining a visible picture.
- concerning the radio reception, everybody knows that a weak signal will impede the reception of stereo programmes and cause hissing.
