Alpha Power makes a digital antenna switch (called the DAS, of course.) It's
designed for use with the Alpha 87A computer-controlled amp (a great choice
for a remote controlled amp if you can afford it.) However, the DAS will
work stand-alone without the 87A. It accepts ASCII commands through a serial
port. It's pretty expensive ($495), but will control up to 36 antennas.
There's a picture and info sheet at Alpha/Power's web site:

>Hi:

>I'm very close to finalizing my remote control station. I have the rig

>From all I have read, most folks use an lpt port for antenna switching.
>In my particular case my only option is a serial port. I will have two
>serial ports available at the remote end, one for rotor control and the
>other is open and I would like to use it for antenna switching. Please
>note I will NOT have a computer at the remote end just the rig, a modem
>and a black box.

>Does anyone know have a software/hardware set up to handle this?
