I checked into the directed perception units, and here are the specs, but
WAY pricey!!
Enclosed are specs for the Miniature Computer-Controlled
Pan-Tilt Unit that you requested.
The PTU-D46-17 is a high-performance, low-cost pan-tilt that
moves over 300 deg/sec with 3.086 arc minute resolution. Measuring
only 3" x 5.1" x 4.25". Load capacity is over 6 lbs (50% greater than the
PTU-46-17.5 model!) Plug-and-play using RS-232, or RS-485
network, host commands precisely control unit speed, acceleration,
position and configuration. Self-calibration upon reset ensure
reliable absolute positioning. On-the-fly changes support both
position and velocity servocontrol. Designed for battery-powered
operation, it provides power management commands and flexible
input power requirements.
The PTU-D46-70 is a higher gear ratio version that has a 9 lb
payload rating (50% greater than the PTU-46-70 model!). It offers 0.77 arc
minute resolution, and a top rated speed of 60 degrees/sec.
In addition, a nodal option is available which allows you to mount
your load at the intersection of the pan and tilt axes: this can
be useful when you want to minimize image motion induced by panning
and tilting, laser pointing, etc.
Other options include:
* High performance AC/DC international power supply
(model PT-PS-INT30V)
* Weatherized option provides outdoor use
* Extended I/O option: control from an analog joystick,
mouse/trackball, control other RS232 devices
* C Programmer's Interface (model PTU-CPI) which provides easy
programming from your host computer, and support for binary
communications (important for high update rate applications
like tracking).
Attached is our standard price list. OEM and distributor pricing
is available.
Please let us know if we can answer any questions or help in solving your
application requirements!

Subject: Re: [BAWUG] Computer-controlled pan/tilt mount for antenna?
well most of the computer controlled mounts I work with are equatorial
whereas what you're probably looking for is altitude-azimuth mount.
directed perception makes such items for security cameras... this came up
on bawug before sometime in 2002 don't know what came of it...
http://www.dperception.com/ptu_over.htm
http://lists.bawug.org/pipermail/wireless/2002-May/006544.html
There are products in the maritime and defense industries that are two
axis computer-controlled mounts but most the the items I've seen that fall
into that category are mounted on vessels not small automobiles.
I would probably exhaust all options involving omni-directional antennas
before I headed to far in this direction.
