One institution I'm familiar with (not designated a prison, but with prison level of security) receives and decodes the digital muxes, then multicasts the chosen program streams over ethernet to the TVs. |

Sometimes I feel so dismal about my trade. The odd thing is, when you talk to the guys who do things like that they are often not cowboys, in the sense of not being people who do a deliberately bad job for the sake of economy and speed. They are almost conscientious, in that they really feel that they do a half- decent job. The problem seems to be that they have never had any training, and have simply fallen into bad habits, doing the job the way they have always done it. They lack the intelligence to look at other people's work and learn from it. Bill |

It is bad if it is keeping him awake and liable to come crashing down. And having three antennas, decreasing in size down the pole, all pointed at the same transmitter, and positioned too close together just does not make sense even to a non-professional observer. |

Rubbing on the platic gutter I suppose. http://www.digitalspy.co.UK/forums/showthread.php?t=1261058 I mean, in the great scheme of things, is it so bad? No, but as I implied in an earlier post it is representitive of so much of the work that's done. And having three antennas, decreasing in size down the pole, all pointed at the same transmitter, and positioned too close together just does not make sense even to a non-professional observer. The lower two aerials could be 'squatters'. We often get these on the masts of our communal system aerials. We have to remove them for insurance reasons. The resident is usually very angry -- with us, not the cowboy installer. Anyway, take a look at http://s19.photobucket.com/albums/b1...ew=slideshow#/ Comments welcome. Bill |

I was heartbroken to see an aerial I installed about 12 years ago for a friend, has suffered a similar bodged up fate by the new owners of the house. It's a heartbreak I suffer on frequent occasions. Here are some examples: I installed a large aerial for a communal system in January. It was in a very poor reception area so the aerial performance was critical. Driving past a few weeks later I saw that a vertical glass fibre colinear had been clamped to the mast, with the radiating element inbetween the directors of my aerial. So far I have not been called back. At another communal system in deepest Derbyshire I fitted a four element DAB aerial and an FM aerial. These were on the main aerial mast below the UHF aerial. They were important because indoor radio reception in that area is very poor indeed. Whilst on site to fix a faulty multiswitch I saw that the DAB aerial had been slackened off and swung through 180deg, in order to make room for a B & Q TV aerial. This had a white cable running across the flat roof to the lift motor room. When I enquired of the caretaker he became extremely shifty. It transpired that he had set up a cozy nest in there, complete with electric fire, easy chair, kettle, and TV set. On the wall near his TV set was an enclosure that contained two multiswitches, with a total of six spare outputs. There's a 1960s Swiss-style bungalow near here that has a gable end overlooking the main road. The resident wanted the aerial on that gable because it looked better from the front of his house. The roof overhang was about a metre, so big wall brackets were called for, but when the installer (not me) explained this to the customer he said he didn't like the idea of the big brackets, so could the aerial be fixed to the wooden fascia. This was done, with a warning that if it caused creaking noises or otherwise mishehaved it was on his own head (not literally, we hope). Anyway, the installer told me this tale and I noticed the aerial when I drove past. It didn't look very secure. Then, a couple of years later, a bloke rung me up and said he wanted to buy a TV aerial and an FM aerial, and some cable. I don't really like this sort of thing (we aren't retailers) but in the end I sold him a four element FM aerial and an 18 element TV aerial. The next time I drove past the bungalow the two aerials were clamped to the mast of the original TV aerial. The whole thing looked vary precarious.However, a few weeks later I noticed that the FM aerial had gone; probably having been moved into the loft. Some Polish tenants put an 85cm dish half way up the mast of my new communal TV aerial, so they could get Polsat. This became as issue when the cable tapped on another tenant's window. At a local residential hospital I found that the poor DTT reception on 120 TV sets was caused in part by two extra downleads having been taped into the aerial cable, with no splitter. These ran to two patient waiting areas. Works Dept were responsible. Bill |
