JBCP-H - Circular High Power "Optimizer"

JBCP-H

The JAMPRO Optimizer High Power FM Broadcast Antenna

JBCP-hThe JAMPRO JBCP-H FM side mount antenna is designed for broadcast applications that require relative insensitivity to icing conditions as well as high power handling. Each element is fabricated with high strength thick wall brass and copper with a 3-1/8" outside diameter. Capable of handling 40 KW, the JBCP-H is one of the highest power side mount FM antennas available. On a single frequency, VSWR is 1.2:1 +/- 200 KHz optional 1.10:1. Deicers are not normally needed, because even with 1/2" of radial ice, typical VSWR is still less than 1.4:1. Each JBCP-H antenna is factory VSWR tuned; optional field tuning may improve VSWR. This antenna is designed with the same principles as JAMPRO's patented PENETRATOR series of FM antennas, which set the industry standard for FM side mount antennas. The shunt fed design eliminates the need to "slug tune" the antenna in the field for optimum performance. Unlike similar, older designs, the Optimizer uses low impedance bays for un-excelled stability and band pass.
