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.
Normally we just say SWR, implying VSWR. But don't forget that what is being described is the voltage distribution along the transmission line caused by the mismatch between the transmission line and the load or antenna. In our example, the SWR on the transmission line is 5:1. This is equal to the ratio of the antenna impedance (10 ohms) to the transmission line characteristic impedance (50 ohms). Thus, without knowing anything else, we know that the maximum voltage along the line is 5 times the minimum voltage.
