[ETO_Alpha] Pin Diodes

Mon, 4 Mar 2002 16:36:41 -0700

I was told by a tech at Alpha, that with an ungrounded antenna an
electrostatic charge can kill the pin diodes. I was never quite sure what
this was all about but, I subsequently, installed an antenna switch. When
the rig is not in use the antenna is not connected. No pin diode problems
for years.
