[FedCom] Transporter Picture

[Mark Cobbeldick [KB4CVN]]

If you look at the photograph of the tractor, and enlarge it, in
addition to the sat antenna on the top of the truck (behind the wind
cowling), you will see three antennas on the roof of the truck.

Left to right they look like:
---------------------------------------

- MaxRad (MHB5800 Series) vhf-highband 5/8-wave whip

- AM/FM broadcast radio whip

- MaxRad (MLB Series) vhf-lowband whip


....I seem to remember several years ago that DoE was also using
VHF-Lowband meteor scatter communications for their fleet of trucks.

Several major transportation carriers use meteor scatter comms in the
40 MHz region, including: trucking companies, BNSF Railroad.

and
<http://www.tessco.com/products/displayProductInfo.do?sku=14891&eventGroup=4&eventPage=1>
for photos.  Both MaxRad and Antenna Specialists were acquired a few
years ago by PcTel Corp. <http://www.pctel.com/prod-index.php>)
