HCJB WORLD RADIO ENGINEERS DESIGN, INSTALL SATELLITE DISH
2/2/2001 1:31:17 PM
HCJB World Radio engineers again have demonstrated that they can design and
build high-tech equipment that is much less expensive and comparable to
anything on the market.
Engineers are installing a 10-meter (33-foot) satellite dish antenna at the
ministry's broadcast compound in Quito, Ecuador, that will receive
syndicated Christian radio programs from North America for airing worldwide
via shortwave. Installation will be completed in about a week.
"By designing and building the antenna ourselves, we are saving thousands of
dollars," says engineer Doug Weber. He adds that the satellite dish will
reduce the mission's operating costs and simplify the delivery of radio
programs produced in the U.S. In the past, tapes, CDs and digital recordings
had to be sent through the mail system.
Alex Saks, acting general manager of Radio Station HCJB, says the dish had
to be large enough to pick up signals from a satellite aimed primarily at
North America. "One of the project's challenges was receiving the signals
without blocking out the sun from the entire compound!"
He adds that the dish will "facilitate and ensure continued broadcasting of
quality Christian programs and teaching to people in parts of the world
still not being reached with the gospel in any other way."
Engineer David Russell, now serving at the HCJB World Radio Engineering
Center in Elkhart, Ind., submitted a recommendation and preliminary design
for the 10-meter dish. Engineers Steve Sutherland and Germán Jaramillo at
the ministry's international transmitter site in Pifo then examined many
antennas and gathered information on what would constitute a sound
"With such a massive construction, decisions on how to support the reflector
and maintain its intended parabolic curve were critical," Russell says.
"From my perspective, this was by far the biggest feat in the antenna
The Pifo staff, led by engineer Gonzalo Carvajal, also received help from
civil engineer Emily Cheung in Quito who dealt with issues such as the
equipment's ability to withstand strong winds. Performance testing will
begin soon after installation under the direction of engineers Marlin
Brubaker and Milton Pumisacho.
