ン受像機。[Claims for Utility Model Registration] A rod antenna connected to a tuner via a signal switching contact, and an external antenna connection jack for connecting an external antenna to the tuner, wherein the signal switching contact is normally closed. The received signal of the rod antenna is applied to the tuner via the signal switching contact, and when an external antenna is connected to the external antenna connection jack, the signal switching contact is opened and only the received signal of the external antenna is applied. In a small television receiver such as that provided in the tuner, a high frequency amplification means is inserted between the rod antenna and the signal switching contact for amplifying the received signal of the rod antenna, and 1. A small-sized television receiver, comprising: a power source connected to said high frequency amplification means for driving said high frequency amplification means.
