Antenna Matching Coil Adjustment Procedure
- Without this basic knowledge, addressing antenna problems, RFI problems, and matching problems, results in a frustrating situation. Procedure which must be followed to properly adjust a shunt matching coil.
- RadioWORKS is a tool for calculating various items related to radio waves and radio wave propagation. Get detailed information about a frequency, such as the free-space wavelength, band classification, propagation methods, common transmitter configurations, etc. Calculate antenna lengths or frequencies. View a 3D coverage map by providing a latitude / longitude coordinate and transmitter height.
