What type of filter might be connected to an amateur HF transmitter to cut down on harmonic radiation?

Why do modern HF transmitters have a built-in low pass filter in their RF output circuits?

What circuit blocks RF energy above and below a certain limit?

What should be the impedance of a low pass filter as compared to the impedance of the transmission line into which it is inserted?

In order to reduce the harmonic output of a high frequency (HF) transmitter, which of the following filters should be installed at the transmitter?

To reduce harmonic output from a transmitter, you would put a _______ in the transmission line as close to the transmitter as possible.

To reduce energy from an HF transmitter getting into a television set, you would place a _______ as close to the TV as possible.

A band pass filter will:

A band reject filter will:

A high pass filter would normally be fitted:

A low pass filter suitable for a high frequency transmitter would:
