loft-aerialLoft aerial antennas are a group of antennas that are not placed at the outside of your house for the purpose of receiving a higher quality signal for your radio or television. There is nothing like loft aerial only that all aerials are built to go outside the room in order to bring a sufficient signals and which can be placed in the loft where the signal is stronger. Some aerials are more suitable for loft installations while others are not but this is just a design capability.

It is true that aerials work better in open places where there is no interference like a roof or any other structures blocking their wave transmission. At times TV antennas may reasonably work well in lofts provided that the signal strength there is sufficiently strong enough. When the transmission power went up from 20kw to 200kw, many areas have now gotten a chance to be in descent status of signal than where they were before this hence signal transmission is improved and loft aerials are constantly gaining popularity because people have realized that they can still get a clear signal even if they did not place their antenna in the open. As this is true and seems to be good news, it is therefore, not recommended to install loft antennas in places where signal strength is very poor.

Normally when you are experiencing a poor signal reception, it is recommendable that you go for an antenna with a higher signal gain so as to solve that problem. Also installing your antenna on the loft will reduce the amount of signal loss as evident from the attenuation level graphs which show that the loss is high when the antenna is place far away from the signal receiver. This is brought about by the increase in frequency and the higher the frequency, the higher the loss.

Frequency attenuation occurs in different dimensions intensities depending on the material from which the roofing is made. The losses of the signal ranges from 3-10(decibels) and one of the solutions the reduce this loss is by the use of loft antennas which greatly curb this vice by over fifty percent. Attenuation levels can fluctuate in some materials under certain conditions that are subjected at that time and the effect can last long or just happen within a short period of time. The conditions that might bring the subject include rain and the presence of a solar which is known to bring attenuation in great heights. Before you decide on which kind of aerial you install, you should be in a position to tell how much interferences will your signal experience, this will help you in specifications of the antenna you should purchase.
