2. 10-meter band - Wikipedia

   en.wikipedia.org/wiki/10-meter_band

   President HR2510A, a mobile 10-meter radio, with a Uniden microphone. Being a very wide band in HF terms, many different transmission modes can be found on 10 meters. Morse code and other narrowband modes are found toward the bottom portion of the band, SSB from 28.300 MHz up, and wideband modes ( AM and FM ) are found near the upper part of ...

   A Yaesu FT-891 Radio Tuned to the 10 Meter Band. The Yaesu FT-891 is a HF and 6 meters all mode mobile amateur radio transceiver. The FT-891 was first announced to the public by Yaesu at the 2016 Dayton Hamvention. [1] The radio has 100 watts output on CW, SSB, and FM modulations and 25 watts of output in AM. [2]

5. Antenna types - Wikipedia

   en.wikipedia.org/wiki/Antenna_types

   A horn antenna has a flaring metal horn attached to a waveguide. It is a simple antenna with moderate gain of 15 to 25 dBi, used for applications such as radar guns, radiometers, and as feed antennas for parabolic dishes. Slot Consists of a waveguide with one or more slots cut in it to emit the microwaves. Linear slot antennas emit narrow fan ...

6. Citizens band radio - Wikipedia

   Over the next several years antenna regulations were relaxed, with antenna length increasing to 1.65 meters (5'5") and centre- or top-loading of the main radiating element permitted. On 1 September 1987 the UK added the usual 40 frequencies (26.965–27.405 MHz) used worldwide, for a total of 80 channels at 27 MHz; antenna regulations were ...

   Moxon antenna for the 20-meter band.The antenna is the faint rectangle of wires held in tension by the bent X-shaped support frame. Moxon antenna for the 2-meter band. The Moxon antenna or Moxon rectangle is a simple and mechanically rugged two-element parasitic array, single-frequency antenna. [1]
