User Report: Aldena Antennas Translate Success
pair of Aldena ALP 05 0 2912 antennas, center of the mast, put WGNY’s
W247AW onto the air.
N.J. — As a broadcast engineering consulting firm in the congested
Northeast portion of the country, we have faced a number of
challenging FM antenna pattern design projects in an effort to
optimize FM coverage for many station clients. This review describes
fill-in translator projects, which can be the most demanding because
the antenna pattern must meet all FCC protection requirements as well
as keep the translator’s 60 dBu contour inside the pertinent AM or
have chosen to use Aldena antennas and software for the most
demanding pattern applications based on multiple factors. Most
important is the fact that Aldena offers a pattern design software
program called EMLAB which allows the user to design an antenna
pattern based on specific radiation limitations using both Aldena’s
own extensive line of FM (also TV) antennas as well as antennas from
other manufacturers. Having this software is important since without
it one would need to rely solely upon the manufacturer, which takes
away the opportunity to do “what if” scenarios that most
engineers like to do to optimize coverage.
important are the quality of materials and workmanship of Aldena’s
antennas. It is rare that engineers don’t comment positively on the
quality followed by a later communication saying “beautiful, low
VSWR, the coverage is excellent.”
in Hackettstown, N.J., installed a DA array of three ALP 05 02 912
five-element, circular-polarized, yagi antennas for the W284AQ FM
translator in August of 2012, just in time to make it through
Hurricane Sandy last fall and then the heavy blizzard conditions in
February 2013. The WRNJ 2 mV/m contour is filled in by a second
translator, W224AS, using ASR 03 02 315 three-element yagis set at 45
degrees for slant polarization.
station reports, “We’ve found the antenna systems to be extremely
rugged and virtually unaffected by the winter ice. Reflected
power is always a watt or two at most all conditions during the
year.” This AM licensee also comments that most of their listeners
are on FM due to the consistent coverage especially when compared to
their night DA coverage.
the spring of 2012 WGNY(FM) Rosendale, N.Y., implemented W247AW using
two ALP 05 0 2912 circular log antennas in Poughkeepsie, N.Y. Our
contact with folks from WGNY indicates stable operation since
installation with no known reports of ice impact on performance.
