Harris bought M/A Com in 2009, IIRC.
When ENG trucks were a relatively new tool in the news gathering
arsenal, (late 70's early 80's) M/A 13GHz "shoebox" microwave
links were pretty common on each truck. Usually with a horn antenna on
the TX and RX. They aren't as directional as a dish, so you didn't have
to be quite so picky about having the both pointed directly at each
other on a straight line.
The Shoebox units allow setting the camera where it was desired, and the
truck where it could hit the ENG receiver. The shoebox link would
provide the video and audio path when a cable-reel run wasn't really feasible.
This was before a lot of stations had developed a plethora of receive
sites, so getting the truck parked where it could hit one of the/the
only ENG receiver was one of the keys to getting a live shot to work.
Here's an interesting article about 1978-era ENG in an Oct. '78
Popular Mechanics. Begins on page 220.
The shoebox units are mentioned on Page 226, after a description
of the 2GHz units worked.
Seems to me that Tim Stoffel and I were just talking about 13GHz links
last week... and if I recall correctly, he was telling me it's become
very difficult to use them due to licensing and siting issues.
In the US, the 2GHz Broadcast Auxiliary Service (BAS) bandwidth and some
other fixed microwave services were shuffled under Part 74.690 of the
rules, so Advanced Wireless and Mobile Satellite Services could use some
of the spectrum. Cell phone carrier Nextel (now part of Sprint)
paid to provide new gear to stations in order to get access to
their former spectrum.
Licensing and operation of BAS and television remote pickup stations is
covered under Part 74.600 of the FCC Rules.
Here's the 2009 PDF version that the FCC's website page on Microwave
services links to.
Check to see if there's a 2010 or 2011 version.
Ed: If you own one of these 13GHz units, and have ideas about
using it in your news gathering activities, you might check to see what
kind of status you have. Could you qualify as a license as a broadcast
network? Or as a common carrier providing Local Television
Transmission, as mentioned in Part 74.602, 4, e:
common carriers in the Local Television Transmission Service (Part
101) may be assigned frequencies
available to television broadcast station licensees and broadcast network
entities for the purpose of providing service to television
stations and broadcast network entities, respectively.
That's covered here:
and found in the rules under Unde r Subpart J, which begins at SS
101.801. That's on page 771 of the PDF linked here:
