Aerial Installer Essex
Thursday 4th July and were off to a new aerial install Essex CM7, upon arrival we found it difficult to get to the flats which were on the pedestrianized high street of Braintree. Once we realised the pedestrian high street was except for access we were ok. The flats had no rear access for our ladder and kit to go, so kindly a shop with access to the rear of the property kindly allowed us to take our kit through to be able to access the roof. After surveying the roof we decided to take some test readings with our aerial and take a look at signal strength and best location to site the new aerial.

Next time down we were kindly offered a cup of tea which was most welcomed, we carried through our drill, T&K wall brackets and fixings. We soon had the T&k wall brackets up high in our chosen location and with the large U` bolts in ready to receive the new aerial. I choose a log-periodic w/b aerial with the reading of the test aerial I knew it would perform very well with the given signal strength and quality of the signal available. Next task was to go back to our van and get a log periodic aerial along with an 8ft 1” ½ alloy mast and of course a reel of cable (black). Feeling like pack horses we lumped all our gear through the shop and up the fire stairs to the roof top. Hard work climbing up a fire ladder with a spectrum analyser, tool belt, 8ft mast and a heavy reel of cable.

Once the aerial was dropped into the wall brackets I was delighted with the signal quality and strength, 48db on all six digital mux’s, with the aerial now aligned all we had to do was discreetly run the aerial cable down the floors to the distribution room. Fortunately there was a lovely lead flashing where the flat roof met the walls of the building and we decided to put our cable under the lead, keeping it out of sunshine, extending the life of the aerial cable. Next leg was to drop our aerial cable down a floor, which was made easy with the fixings of the fire ladders neatly placed between the top floor and the second floor. With cable ties we soon had the cable to the rear of the distribution room where all we needed to do was drill a neat 10mm hole in to bring the aerial cable through.
With the aerial cable now in the distribution room we ran our cable to the twelve cable ends from the flats. With good signal we used a digital tap to divide our signal in to 2 with a loss of -3.5db. Fantastic now all we had to do was secure 2x 6way pro amps and were done. Testing both amps we were delighted with a perfect signal of 55db on all six mux’s. Job well done!
