    • PROBLEM TO BE SOLVED: To solve problems wherein (1) a mount to be fixed to a parabolic antenna and shipped as an accessory is assembled at a site or assembled before shipment, the former case requires many outdoor works and the work efficiency at the site is considerably deteriorated depending on the work environment, the latter case requires a work of antenna extraction, and revision of the size of package box may be needed, although the parabolic antenna and an ODU main body are ordinarily shipped in a separate state, and wherein (2) a work efficiency is very bad because a work of coating a waterproof adhesive to the surrounding of connection parts of a waveguide is required to keep the waterproof of the connection parts of the waveguide. SOLUTION: The mount having been fitted to the parabolic antenna is abolished, an adaptor is provided to a housing, and both waveguides are configured to be clamped by O-rings so as to enhance the work efficiency and the waterproof.

    • PROBLEM TO BE SOLVED: To solve the problem wherein a video signal inputted into a control unit from the outside is subjected to frequency correction at the control unit for transmitting to an imaging section, and hence a high-frequency component of a video signal input from the outside gives interference to a video signal imaged by the imaging section. SOLUTION: A television camera having the imaging and control units comprises an input for entering the video signal into the control unit from the outside, a frequency corrector for performing the frequency correction to the video signal entered to the input, a transmitter for transmitting the video signal output from the frequency corrector to the imaging section, a switch for changing the video signal transmitted to the imaging section from the control unit to that imaged by the imaging section, and a display unit for displaying a signal output from the switch.
