I think this vintage HP box was used to switch between a TV set and a computer Interface. It appears to be in good mechanical condition. At this point it might be a collectors item. It is untested and sold AS-IS. This switch has a small noise when this switch is shaken. There appears to be no way to easily open this switch to verify if this is a problem.
I was later told by an customer thatthis antenna switch was used with an HP 82163 HP-IL video interface. The impedance of the RF output of the 82163 is 75 ohms, so the switch contains a balun to convert to 300 ohms. Also this switch has been modified with a second balun to convert the impedance back to 75 ohms.

Payment must be from a verified account and shipment must be to the address of the same verified account in the lower 48 United States.
