My first transmitter was a 4 transistor job that had about a 100 Ft range. The standard design allows for overload values of the pressure transmitter of up to 5 times the measuring range value (max. The AMT5000 combines super-high efficiency class E mode RF generation with an efficiency-optimized toroid loading coil for nearly the best efficiency possible. This is long range fm transmitter circuit in vhf range. Transmission Range: up to 100 meters / 300 feet. The audio is clear, the level can be adjusted to achieve 100% modulation, and the range is certainly adequate for our purposes. When producing that AM signal we were talking about, the end result is that it was discovered that approximately half of the transmitter power is "wasted" on the carrier and the rest of the power is divided between the two sidebands. CZH Circular Elliptical Polarized Antenna Double Crossed FM Broadcast Antenna 88~108 Mhz for FM Transmitter Max Power 500w.
