[TenTec] Is The Eagle really soaring yet?.

[Dr. Gerald N. Johnson]

Very poor choice because the 1N4007 has a structure like a PIN diode and 
so is slow to recover at RF, once turned on it makes an attenuator for 
many cycles. That and considerable capacitance makes it a killer of 
receiver sensitivity used as a clipper.
