Masthead Amplifier Survey

67 posts in this topic

Six years later and filtering still does not reduce the errors. It reduces noise which may or may not be the issue. There are narrow band aerials which have higher gain and good band selectiveness, narrower beamwidth etc, and there are products like the mda which now have additional filtering built in. I've used heaps of kingray mda20l and the low noise design, high headroom and little or no filtering has meant I've used it for amplifying c band satellite at a stretch and FM in weak signal areas with little harmonics. The audiophile customer was blown away and I was very happy too. Band pass filters are now cheap and very effective you can choose which channel block you need. Lacey's TV have these.
