I am about to replace my 30 year old Ameritron antenna switch with a DX Engineering unit. It will be placed at the top of the tower to select between the various antennas - wire slopers for 160 and 80, inverted vees for 75 and 40, and the Steppir ( currently under repair) for the rest of HF. I will not have multiple antennas selected at the same time. What is best - to wire the switch so that unused ports are normally grounded or open? My inclination would be to ground all the unused antennas, but since the switch is shipped normally open I have an element of doubt.
Thanks --
