JAMPRO's Circularly Polarized Spiral Antenna provides the television broadcaster with the industry's technically finest CP antenna with a proven, in-use design, featuring superb performance in a rugged yet simple mechanical structure. The antenna is customized for each application and can be supplied for any single VHF or UHF channel: 2-70. Dependent upon system requirements, the spiral is built in either two or three sections and provides omnidirectional, circularly polarized power gains from 2 to 15 (or even higher on special order).
The spiral design provides an almost perfect horizontal pattern circularity of +- 1.0 dB(VHF) and +- 0.5 dB(UHF). Axial ratio, a true measure of performance of circularly polarized antennas, is excellent at only 1.5 dB. Electrical beam tilt and null fill are standard. The amount of each may be directed by the customer and his consultant to suit local conditions. Power input to the spiral is a standard EIA 50-ohm connector as specified.
