Description

Features
CAT-283 is an antenna tuner for 144MHz/430MHz band, capable of inputting up to 250W of transmitting power, with a single connector for both 144MHz and 430MHz band.
The meter can simultaneously measure the traveling wave, reflected wave, and SWR value by adopting the cross method. The meter is designed to be compact and lightweight by switching the use of one meter between 144MHz and 430MHz bands.
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-283 has a built-in duplexer inside and 144/430MHz comes out as one.
(MP-NP50cm cable) is required when the connection to the radio is an N-type connector.
In the case of the MP cable terminal on the antenna side, direct connection can be made, but in the case of the NP type, a conversion connector (MP-NJ connector) is required.

Input impedance 50Ω
Output impedance 15Ω to 200Ω
Allowable Pass Through Power 250W or less (FM)
Minimum SWR measurement power 6W or more
Power supply for illumination 11V to 15V DC, approx. 250mA
Connector M type
