2. Radio receiver - Wikipedia

   en.wikipedia.org/wiki/Radio_receiver

   The antenna may be enclosed inside the receiver's case, as with the ferrite loop antennas of AM radios and the flat inverted F antenna of cell phones; attached to the outside of the receiver, as with whip antennas used on FM radios, or mounted separately and connected to the receiver by a cable, as with rooftop television antennas and satellite ...

3. Whip antenna - Wikipedia

   en.wikipedia.org/wiki/Whip_antenna

   Vertical whip antennas are widely used for nondirectional radio communication on the surface of the Earth, where the direction to the transmitter (or the receiver) is unknown or constantly changing, for example in portable FM radio receivers, walkie-talkies, and two-way radios in vehicles. This is because they transmit (or receive) equally well ...

4. Antenna types - Wikipedia

   [y] The simple antennas used to make a Yagi-Uda can either all be linear or bent linear antennas, or all loops (a quad antenna) or (rarely) a mixed combination of loops and straight-wire antennas. Yagi–Udas are used for rooftop television antennas , point-to-point communication links, and long distance shortwave communication using skywave ...

5. Directional antenna - Wikipedia

   en.wikipedia.org/wiki/Directional_antenna

   Patch antenna gain pattern. A directional antenna or beam antenna is an antenna which radiates or receives greater radio wave power in specific directions. Directional antennas can radiate radio waves in beams, when greater concentration of radiation in a certain direction is desired, or in receiving antennas receive radio waves from one specific direction only.

6. Antenna (radio) - Wikipedia

   en.wikipedia.org/wiki/Antenna_(radio)

   This is the type of antenna used in most portable AM broadcast receivers (other than car radios): The standard AM antenna is a loop of wire wound around a ferrite rod (a "loopstick antenna"). The loop is resonated by a coupled tuning capacitor, which is configured to match the receiver's tuning, in order to keep the antenna resonant at the ...

   The ML-2 “Marker Luxury” was a crystal controlled FM transceiver for the 2-meter (144 MHz) band. The TR-22, TR-22C, and TR-33 were very small 2-meter FM transceivers that were entirely self-contained, including a telescoping antenna and rechargeable battery. They each came with a microphone and carrying case with shoulder strap.
