.... Unless you're running a very inefficient antenna, you shouldn't need a preamp for anything 2-30 MHz with any reasonable receiver. Thank You Harold. I've read an article by IK4AUY from QEX Mar/Apr 2003 about Front-End (standalone). He used very nice push-pull preamplifire in it (to compensate insertion loss) - but i wanted to be smarter ;-) And the question should be: "If **I have decided to use RF preamplifire** CAN I use MMIC or should I use more "conventional" solution. ;-) 73 MAc sp9mrn |
