Jampro designs turnkey antenna solution for Millcreek Broadcasting

When Millcreek Broadcasting needed to develop a new antenna site in Utah's Bountiful State Park, they called on Jampro Antenna / RF Systems of Sacramento, California to handle very sensitive site design and installation issues. For aesthetic reasons, the tower had to be low profile, yet had to be able to deliver eight strong FM frequencies and allow for future expansion.
Downward RF levels also had to be at absolute minimum levels at the tower's base. And, of course, FCC and stringent state park requirements had to be met.
Jampro engineers addressed these challenging issues and designed a unique turnkey solution consisting of a custom-cut Jampro monopole tower for minimum height and footprint, a specially configured panel antenna array to reduce RF radiation at ground level, and a customised space-saving eight-frequency combiner. Jampro then tested the configuration at its full-field test range in California to ensure it met all criteria and delivered the components to the Utah site ready for installation with minimum impact on the environment while minimizing RF levels on the ground.
Millcreek's turnkey installation was comprised of a custom designed Jampro JCPD circularly polarized flat panel antenna, one of which was designed to minimize downward radiation and produce the required azimuth pattern. Jampro also supplied an eight module/frequency RCCC-291-0.8 FM constant impedance balanced combiner for the eight frequencies as well as all inter-connecting rigid transmission lines.
The JCPD provides dependable performance in the harshest environments such as those found in Utah winters. For added protection against ice buildup, Millcreek's panels were safeguarded with lightweight radomes. The JCPD antenna has typical VSWR of 1.1:1 or better. Many custom directional patterns are available to fit special coverage requirements such as those needed at Bountiful State Park.
