A portable remote controller (50, 50V, 50W) for a tire status detector (30), includes a portable casing (51), a transmission circuit (53) disposed in the casing (51), a low-pass filter (56) disposed at an output side of the transmission circuit (53) for permitting a signal with a frequency of not more than the first frequency to pass through the low-pass filter (56), a receiving circuit (54) disposed in the casing (51), a high-pass filter (57) disposed at an input side of the receiving circuit (54) for permitting a signal with a frequency of not less than the second frequency to pass through the high-pass filter (57), a ferrite bar antenna (65, 65V, 65W) housed in the casing (51) and including a ferrite bar (65A, 65S) and an antenna coil (150, 153) wound on the ferrite bar (65A), and a duplexer (55) connecting one of two terminals of the antenna coil (L50, L53) to ground (GND); and the other terminal of the antenna coil (L50, L53) in common to the filters (56, 57) so as to be composed of the filters (56, 57), thereby using the ferrite bar antenna (65, 65V, 65W) both for transmission of the long-wave signals and for receipt of the ultra high frequency signals.
