Multiband antenna It is easier to design a multiband quad antenna than a multiband Yagi antenna. Higher gain The 2-element quad has almost the same gain as a 3-element Yagi: about 7.5 dB over a dipole. Likewise, a 3-element quad has more gain than a 3-element Yagi. However, adding quad elements produces diminishing returns:
A quad antenna is a self-resonant loop ... This design can also be turned 45 degrees to a diamond ... Car-roof-mounted 6-meter halo antenna for mobile ...
A competing third criterion is the number and bandwidth of the frequenc(y/ies) that a single antenna intercepts or emits. A fourth design goal is to make the antenna directional: To project or intercept radio waves from only one vertical and / or horizontal direction as exclusively as possible. Simple antennas
A Yaesu FT-857D tuned to 50.125 MHz, the traditional 6-meter single-sideband calling frequency in the United States. [1] The 6-meter band is the lowest portion of the very high frequency (VHF) radio spectrum (50.000-54.000 MHz) internationally allocated to amateur radio use. The term refers to the average signal wavelength of 6 meters. [a]
In antenna terms, each of the conductors making up the antenna is known as an element. [9] To calculate the net result, NEC breaks the antenna's elements into a number of sampled points, called segments. It uses simple calculations based on the diameter of the conductor and the wavelength of the signal to determine the induced voltage and ...
An ICOM IC-7300 Radio Tuned to the 20 Meter Band. The ICOM IC-7300 is a multimode 6 meter, 4 meter (ITU Region 1 only) and HF base station amateur radio transceiver. [1] The IC-7300 was announced to the public at the Japan Ham Fair in 2015. [2] The radio has 100 watts output on CW, SSB, and FM modulations and 25 watts of output in AM. [3]
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]
With a low power home station and a simple antenna, range would be around 50 km (30 miles). With a large antenna system like a long yagi, and higher power (typically 100 watts or more) contacts of around 1 000 km (600 miles) using the Morse code (CW) and single-sideband (SSB) modes are common. Ham operators seek to exploit the limits of the ...
