There is a difference between getting a TV aerial installation done by a fully qualified professional aerial & satellite engineer and a guy that is installing the odd aerial on a part-time basis to help boost his income. With the pro, you will more often than not find that they are fully insured to work on your property, which is important as any accidents caused by the fitter will be covered by their public liability insurance including any injuries caused to you or your family. The part time installer will in most cases have no insurance at all and as the owner of the property, you will be in most cases left to shell out for any damages caused by him.
The next noticeable difference between these engineers will be both the equipment they use and also the quality of the digital aerial fixtures and fittings. Where as the part-time aerial fitter will be buying cheap contract aerials to install, the professional will have a range of digital aerials ready to be installed according to the needs of the home. For instance, if the TV aerial needs to be split into multiple rooms, the pro engineer will pick the antenna accordingly, a part-time fitter will not and can tend to install multiple cheap antennas on one mast with no splitter in sight. The cost can usually be the same, but the job done by the professional will look better since there will only be one good high gain aerial and the signal and quality can often be much better. Plus, with the cheaper contract aerials, they don’t even last a year before falling prey to water ingress and complete failure.
As well as the quality and performance of the aerial are the quality of the coax cable, the connectors whether they be coax or f-plug connectors, blast covers etc will be of a better quality and will, therefore, last many years longer. Buy cheap pay often is a phrase that is well known, and it applies in this case since it is very often the case. Going for a cheap installation can in many ways prove a false economy, & by just paying that little bit extra for a professional, will reap benefits from day one. Having the job done correctly, neatly and in such a way as to hide the unsightly cable where possible should bring the customer confidence in recommending the engineer to friends and family.
