[QUOTE="rolfw, post: 64188, member: 175057"] The margin rising device for the DAT45 may help, it certainly isn't expensive, but if you say that your friend had a filter fitted and it solved the problem, then that is what you should be aiming for. An Amplifier will amplify the signal, but amplify noise as well, whereas a filter will as it suggests filter out unwanted transmissions on different frequencies, which may be causing interference or attenuation to the required signals. High output VHF signals are renowned for causing upset to their higher frequency UHF neighbours. There are some nice combined units now, which serve as an amplifier and Filter/channel equaliser, but the price is prohibitive for anything other than large commercial applications. [/QUOTE]
