Greenville, NC, 21 September 2007 –- LBA Technology, Inc. announces the CAMI series of new-concept broadband medium-power isocouplers for AM towers. CAMI isocouplers permit other antennas to be mounted on “hot” AM towers.
CAMI systems are specifically targeted to isolate single auxiliary broadcast coaxial cables for STL’s, FM translators, low power FM, and television translators. Unlike commonly used isocouplers, one CAMI fits all of these applications. They also have the advantage of passing AC or DC current to tower top amplifiers, and are more resistant to weather and lightning.
Typical CAMI system specifications are:
- Broadband transmission frequency: DC – 2000 MHz
- Broadband impedance: 50 ohms, VSWR <1.2/1
- Insertion loss: 1.2 dB @ 100 MHz, 2.6 dB @ 960 MHz
- Broadband power capability: 2.0 kW @ 100 MHz, 250 watts @ 960 MHz
- DC power passing
- AM isolation frequency range: 500 – 2500 kHz
- AM working voltage: 10 kV peak
- Lightweight, fast installation
With pending FCC approval of translators for AM daytime stations, CAMI will provide an simple, cost effective, way to mount the translator antenna on existing AM towers without major changes to the transmitting system.
LBA Technology President Jerry Brown commented “The CAMI isocoupler brings simplicity and reliability to the installation of other services on AM towers. The uninterrupted, stable, low loss signal path for these services is a real advantage. The rugged environmentally hardened construction will pay real dividends in reduced ongoing maintenance costs.”
The CAMI isocoupler is priced competitively with other, less capable isolators, and units can be shipped immediately.
LBA will have a CAMI on display at Booth 528 at NAB Radio 2007 in Charlotte.
