| IBOC FM
– FLEXIBLE ANTENNA CHOICES |
|
|
The least complicated method of adding
the IBOC digital signal to any FM station
uses a separate transmitter and antenna
at the existing tower site. FCC specifies
that it be licensed as “auxiliary” and to
be
operated under special temporary authority
(STA). Other conditions apply. Here, a 4-bay
SWR Digital Partner FM antenna is mounted
below the WDUQ analog antenna at
DuQuesne University. |
|
| This
SWR FM panel antenna uses hybrid combiners at each level to
inject the IBOC digital signal for WLTJ at Pittsburgh, PA. The
system uses a circulator in the digital feed line to improve
isolation. This method conforms to the original IBOC FM proposal,
and it requires no special FCC licensing or authorization. |

The illustration to the left portrays the
new SWR ILLUMITRON-HD FM antenna, which delivers best
signal quality and coverage for both analog and digital
components. It will eliminate sidelobes and downward radiation,
reducing RF interference and multipath. It provides excellent
isolation and bandwidth without the use of hybrids or
circulators. It is guaranteed to outperform any manufacturer’s
IBOC compatible FM
antenna regardless of price.
