Antenna is the most important element There are 4 simple types that one can use for the FM transmitter. A—GP (Ground plane), B-Dipole, C- Reflected Folded dipole, D- Folded Dipole, E- Yagi. They are Omnidirectional, bi-directional, uni-directional & heavily directional. Discussed below a few for the amateurs. Complicated parameters like bandwidth. Gain, SWR, etc are all not covered for simplification except the impedance(Z) of the antenna which is important. The best way to increase the range of your FM transmitter is to use a matched antenna as per the impedance without which one gets very little range coverage. The cable, impedance matching, and height at which it is installed are also important. Any obstructions in the line of sight also affect the range. For example, one can get up to 1 to 2 KMs for a one-watt transmitter, 5 to…
