Antennas have a vector sum of all the accumulated signals arriving at any one time. Peak voltages can be very high. For example I can light the filament of a 12V incandescent 50 mA lamp to a red or yellow color with my Beverages at night, after the amplifiers. The Hi-Z amplifiers, if they are older units, have an output TOI of about 10 dBm. The DXE amplifier has an output TOI of about 45 dBm. You added a limiter that is advertised to "hard" saturate at -.5 dBm into 50 ohms, or -2.2 dBm into 75 ohms. (It is spec'ed at .3 volts peak, which is .212 volts RMS.) This means your system probably has a TOI of about 0 dBm or less. A limiter like that would make any receiver have Knight Kit Star Roamer dynamic range. :-) _______________________________________________ UR RST IS ... ... ..9 QSB QSB - hw? BK
