The average reception gain in the horizontal polarization of the VHF band of the TV broadcast wave in 1 to 12 channels of the FM radio broadcast wave of 76MHz to 108MHz according to m is measured, and the reception gain of the standard dipole antenna is set to 0dB. The gain difference (hereinafter abbreviated as the dipole ratio) is +2.5 dB and +4.8 dB, respectively, and the reception gain of the conventional roof-mounted Yagi antenna is F.
The average value of M radio broadcast wave and TV broadcast wave is about +5 dB and about +5 dB, respectively, and the tabletop antenna is about +1.5 and about +2.3 dB, respectively.
Although it is inferior to the roof-mounted Yagi antenna, but few, it is superior to the tabletop antenna and can be used practically.
