If I use back to back diodes across my receiver antenna input to protect it 
from transmitted energy, will this cause additional intermodulation beyond 
anything I would otherwise experience in normal operation?  I was thinking 
of three 1N4148s in each direction, for a total forward voltage drop of 2.1 
volts, in combination with a series resistance (either a resistor or a 
small incandescent light bulb.
