Manufacturer number: COMB-TX+RX-3-450465-35W
Product information
Ultra-compact coupling network for interconnecting 3 radio repeaters.
The COMB-TX+RX-3-455470-35W couples 3 radio repeaters in the 70 cm band to a common antenna output.
The high coupling attenuation enables high operational reliability when simultaneous, undisturbed parallel operation of several radio systems is absolutely necessary.
The use of broadband components enables consistent electrical properties over a wide bandwidth. A frequency change within the bandwidth is possible at any time without readjustment.
Extremely compact design in a 19" rack: 2U.
The reduced installation depth of 460 mm enables installation in 19" racks with a shallow cabinet depth.
