New TV Aerial Chelmsford

Thursday before the V weekend, and I wanted to get all my Chelmsford work done before Friday as getting around Chelmsford was going to be difficult.  I received a call in the morning from a customer wanting a new TV aerial Chelmsford so I made sure I could get there the same day, when I arrived the weather was cooler and I appreciated the breeze, but still very muggy and humid.  I looked at my customer’s roof and chimney stack, and was delighted with the position of their chimney stack, as their front room was below, a nice straight cable run down the roof to the sitting room.  We agreed a price and I went up and lashed their chimney stack using a large heavy duty 5 brick course chimney cradle and fitted a log-periodic w/b aerial onto an 8ft 1” ½ alloy mast read to take up with my meter.  When I fitted the aerial and mast into the chimney cradle, I connected my spectrum analyser and rotated the aerial 360degrees looking at all available signals, Anglia was very weak and London was weak too but the best choice of the two.

I aligned the aerial to London and went back down and fetched a variable gain w/b masthead pre-amp as the signal needed amplifying as it was too weak to work without issues.  I connected the masthead and once again connected my spectrum analyser, using a plastic star shaped key I reduced the amplification until the digital signal was still strong, but caring very little noise.  Happy with my signal I connected the new aerial coax lead to the masthead after feeding the coax cable under the lashing wire and up the mast to the masthead, I completely covered the masthead pre-amp’s casing to the aerial mast ensuring it could never fall off or come away from the aerial mast.  Happy with my cabling I fed the aerial cable down my customer’s roof and using the remaining lashing wire I cut u shaped pieces and placed them over the aerial coax cable and under the roof tiles keeping the aerial coax cable pined to the roof ensuring it would stay in place, not move and chafe reducing its life expectancy.

With the aerial cable now on the floor I spotted my customer had drilled a large hole behind their TV for an Ethernet cable to exit their sitting room and go towards the rear of their home to their router, the hole was large enough to accommodate my aerial coax cable too, so I threaded my cable through the existing hole and fed the cable towards the nearest power point for my 12v remote power supply unit.  I fitted the power supply unit and made a return fly-lead to my customer’s TV and re-tuned the TV knowing the signal was 100% perfect; my customers were delighted with all their new channels and fantastic pictures.
