Since many headaches are caused by stress, the best essential oils for headaches are often those that encourage deep relaxation. Rose oil can help comfort and soothe the nervous system, and reduce tension in the body that can lead to tension headaches.
Tuning your antenna is mandatory if you want acceptable CB performance. Not tuning your antenna will result in poor transmission and reception performance, and can also result in permanent damage to your radio. Youâll need an SWR meter (available for around $25) in order to tune your antenna.
Impedance mismatches result in standing waves along the transmission line, and SWR is defined as the ratio of the partial standing wave 's amplitude at an antinode (maximum) to the amplitude at a node (minimum) along the line.ith a different length of transmission line, the source will see a different impedance than Z load which may or may not be a good match to the source. Sometimes this is deliberate, as when a quarter-wave matching section is used to improve the match between an otherwise mismatched source and load.
