New TV aerial Rettendon Essex www.andysaerials.com

Monday morning and were off to Rettendon for a new TV aerial install.  We had already been and completed a site survey and quote a couple of weeks ago, and I had put up a TV aerial for my customer’s neighbour about 10years earlier, and when we arrive to quote I remembered signal was a problem.  My customer had a Unix 52 on a 16ft 2” mast and very few elements remaining, I explained although most of the surrounding houses had aerials on 16ft and 20ft masts, I was not a lover of enormous masts and would go no higher than 12ft.  When my customer called me to go ahead with the work I ordered an Antiference XG10 w/b aerial as I believed the XG10 would be my best choice given the signal difficulties with the area.

As you can see from the attached picture, my aerial (on the right shining), is facing a completely different direction from my customer’s neighbours.  WE took down the damaged Unix and kept the top lashing of the double lashing kit cutting off the bottom bracket.  We fitted a large 5 brick course 13” chimney cradle and adjusted the top bracket to match our chimney cradle.  We put together the Antiference XG10 and put it on a 12ft 2” aluminium mast.  We fitted the aerial to the chimney brackets and plugged it in to the spectrum analyser to see how the signal was behaving.  I was rather surprized to see 25db on my screen but not to see the top 4 mux’s horrid with an inward v, after a little lowering, rotating and re-raising the aerial I managed to get all 6 digital mux’s square.  Strangely enough most of the aerials in the area were much the same as the aerial on the left which had been aligned head on and no compensation made for the reflection of the trees dissipating the digital signal.

Very happy with the signal now I placed a masthead pre-amp on of relatively low gain but only had a noise figure of 2.2db, perfect for raising the signal slightly and firing it down to my customer’s distribution amp.  We ran a new cable to my customer’s amp and discovered their amp was u/s!  I showed my customer my signal on my spectrum then plugged it in to their distribution amp and they could clearly see the signal rolling and disappearing then reappearing.  With a new distribution amp now fitted all we need do was set up their new You-View box demonstrate and leave them to enjoy it.
