CP-1V VHF Circularly Polarized Antenna

$1,335.00

The CP-1V VHF antenna is a leap forward in RF technology. It occupies a small footprint of 18 inches square, but performs more effectively than much larger competitors. It is a true circularly polarized antenna, and covers the entire VHF wireless IEM/microphone/intercom band.

In performance tests, the CP-1V antenna exhibited fewer dropouts and greater overall range. Its rugged construction makes it suitable for both indoor and outdoor use, including hilltop translator use. While not a high power transmit antenna, it handles enough power to make it practical for multi-transmitter VHF in-ear monitor systems.

SUGGESTED USES

VHF wireless microphone receivers
VHF IEM and IFB transmitters
VHF wireless intercom systems
VHF television off-air monitoring
VHF television translator receive antennas
VHF television CATV head-end antenna

SPECIFICATIONS

SWR: Nominally 2:1 or better over the entire band, 174-216 MHz.

Radio Active Designs

Originally designed for use under FCC Part 74 for broadcast and entertainment applications, the UV-1G can also operate as a Part 15 device for general intercom use. Using RDGI’s advanced ENB (enhanced narrowband) modulation format, the system occupies only a 25 kHz wide channel, while providing high quality, 8 kHz bandwidth audio to minimize user fatigue.

The system has superior range, featuring two- and four-wire interfaces for each intercom channel. Highly ruggedized, the UV-1G can be used in a wide variety of environments, while the belt packs are suitable for outdoor use. It can be expanded to accommodate additional base stations and belt packs.

The Impact of Circularly Polarized Antennas

CP-1V, Antennas, Legacy Equipment, Engineering

Until recently, most CP (circularly polarized) antennas were for the UHF (ultra-high frequency) band, as VHF (very high frequency) CP antennas were too large and unwieldy for a lot of applications. That has all changed with the introduction of our CP-1V, a compact, circularly polarized antenna.
