Mast-head amplifiers always were appropriate for 'fringe-area' reception in the old days when there were fewer transmitters around. The dynamic range issues occur closer to transmitters, of whatever type, whose signals get into the front end. If someone puts up a TETRA (or equivalent for your country) base-station near your house you might find amplifiers a lot less effective. Chris For sure. I was on the verge of returning my last analog TV because it wouldn't get one channel at all, and several others were very poor. But then I got an idea and added an attenuator at the antenna input. Problem solved -- got a great picture on all channels. The new HDTV has a better dynamic range and can put up with the strong signals, so it doesn't need the attenuator. I'm about 10 - 15 miles line of sight from urban broadcast towers. I use a commercial TV antenna in the attic. Roy Lewallen, W7EL |
