2. Diplexer - Wikipedia

   en.wikipedia.org/wiki/Diplexer

   An example is maintenance work at one antenna of a medium wave transmission site that has two antennas transmitting on two frequencies. Then the other antenna can be used for broadcasting both channels. If it is not possible to build a second antenna for the second transmitter due to space constraints, then the diplexer is used permanently.

3. Television antenna - Wikipedia

   en.wikipedia.org/wiki/Television_antenna

   The wavelength of 54 MHz (Channel 2) is 5.5 m (18 feet) (λ × f = c) so the antennas must be a minimum of 2.25 m (90 inches) apart. It is also important that the cables connecting the antennas to the signal splitter/merger be precisely the same length to prevent phasing issues, which cause ghosting with analog reception. That is, the antennas ...

For example, to feed a dipole antenna from an unbalanced feedline like coaxial cable, the feedline is connected to the antenna through a balun. Without the ...

9. Fractal antenna - Wikipedia

   en.wikipedia.org/wiki/Fractal_antenna

   Log-periodic antennas are arrays invented in 1952 and commonly seen as TV antennas. This was long before Mandelbrot coined the word fractal in 1975. [4] Some authors (for instance Cohen) [5] consider log-periodic antennas to be an early form of fractal antenna due to their infinite self similarity at all scales.
