Cat-273 Comet 144/430Mhz Antenna Tuner. This product is a dedicated 144MHz/430MHz band antenna tuner capable of inputting up to 250W of transmitting power.Independent input/output connectors are arranged for the 144 MHz and 430 MHz bands, allowing separate use of the 144 MHz and 430 MHz band systems. The use of a cross-type meter allows simultaneous measurement of traveling wave, reflected wave, and SWR values. The design is also compact and lightweight, allowing the use of a single meter for switching between 144MHz and 430MHz bandwidths. The meter scale plate is equipped with an illumination lamp, which lights up at night for easy viewing. (when connected to an external power supply). CAT-273 is designed to withstand 250W input sufficiently, but since very high voltage is generated in the tuning circuit during tuning adjustment and the impedance seen from the radio changes significantly, the transmitting output power during tuning adjustment should be less than 10W (6 to 10W) in order to protect the radio. Do not add more than 250 W of transmit power to this product. Failure to do so may result in malfunction. This product can be tuned in the range of 15O to 200O. If the SWR of the antenna system to be connected is outside this range, do not force the tuning and adjust the antenna system before use.
Never add more than 15 V to the external power supply voltage for the meter's illumination lamp. Please note that the power value will not be indicated correctly if it is less than 6W.Output impedance: 15O to 200O. Allowable Pass Through Power: 250W or less (FM). Minimum SWR (power) measurement power: 6W or more. Power for illumination: 11VDC-15V approx. Dimensions: (W)218 x (H)93 (98) x (D)120 (152) [mm]. We are located in Japan.
