I am a tvsat engineer and install irs systems in blocks of appartments. i live near bradford but do a few installations around newcastle. about 3 years ago i installed a system at bishop awkland for 36 flats and 16 bungalows. the aerialsignal wasnt great but after amplification it was ok. i have signal power records and carrier to noise records and although some multiplexes were weaker than othersin both power and carrier to noise, it was only by 8db.{power}. i tested every tv and satellite point in flats via a promax explora analizer. we have had no complaints for 3 years but recently another tv engineer has been to check the system and says it has been installed wrong and the equipment used is wrong. the main reason for my txt is he is saying there is a masive difference in signal from each multiplex to the flats. I have just installed a system today in darlington and noticed a 20db difference in frequency 21 and frequency 42. i used a log periodic which is meant to balance the signals a bit better than a high gain aerial. i was in a great reception area to bilsdale transitter but still had this variation. viewing my signal records from 3 years ago this variation didnt seem so severe and just wondered if any work has been done or adjustments have happened to the bilsdale transmitter as i have been installing these type of systems for 12 years and am fairly gutted about him saying its all wrong. any help would be greatful.
