How to Build an FM Antenna Out of Coat Hangers

FM radio signals are directional, so tuning in weak signals can depend to a great deal on the antenna you're using to tune them in. The simple dipole antenna design is easy to make from basic materials and provides a big step up in performance from a simple wire antenna. In addition, it ca

Medium-Power FM Transmitter

Description The range of this FM transmitter is around 100 meters at 9V DC supply. The circuit comprises three stages. The first stage is a microphone preamplifier built around BC548 transistor. The next stage is a VHF oscillator wired around another BC548. (BC series transistors are gener

How to make AM/FM Radio Antennas at home

An AM antenna is one thing and an FM antenna is another. They are at opposite ends of the radio spectrum. The AM radio wave is a long wave. The FM radio wave is a short wave. What one needs for an AM/FM antenna is two opposites functioning in the same antenna. Car radios feature AM/FM and satellite

How to Calculate FM Antenna Length

While standard FM antennas are designed for picking up stations operating at a particular frequency range, this isn't always sufficient for amateur "ham" radio broadcasting and reception that operates at different frequencies. Calculating the optimum antenna length is possible wi

How to Set Up an HDTV Antenna

When you no longer want to subscribe to a TV service and wish to save on cable bills, try an indoor digital antenna. If your HDTV is within 15 miles of a TV station or broadcast tower, this antenna may receive the digital signals needed for good reception. Connecting the wires and adjusting th
