    Actual SWR of an antenna

    Posted by wa3ltj on 2025-07-28 at 19:06

    Determine the VSWR of antenna A using the parameters F, X, N, L and defined here.
    The electrical arrangement is: Transmitter with CW signal at frequency F (MHz). The transmitter is connected to a VSWR meter. The VSWR value is the radio N:1.0. The other side of the SWR meter is connected to coaxial cable of length X (feet). The coax cable has a rated loss of L (dB/100ft). The other end of the coax cable is connected to A.

Bias is a tendency to favor or lean towards one perspective, person, or group, often at the expense of another. Bias can be conscious or unconscious (implicit) and can influence judgment, decision-making, and behavior. Unlike prejudice, which is explicitly about preconceived notions, biases can be more subtle and can even occur without the individual being fully aware of them. Bias is broader and can be positive or negative, affecting various aspects of life like decision-making in work, preferences in social settings, etc. Bias is basically a difference of opinion and that must be respected. Prejudice, however, refers to negative, preconceived opinions or attitudes held by an individual or group towards another group or individual, often without factual basis or experience. Prejudices are usually harmful, leading to unfair treatment or discrimination. They are often based on stereotypes and can be about race, gender, religion, nationality, or any other distinguishing characteristic. Prejudice is more about feelings and attitudes. Ham Community does not tolerate prejudice. We are all different, that's fine. Remember, duty and honor are built on respect.
