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] It takes its name from the amateur radio operator and antenna handbook author Les Moxon [2] (call sign G6XN). [1]
Inverted vee antennas are horizontally polarized and have a similar pattern compared to a traditional horizontal dipole. Typical amateur radio inverted vee installed on roof. This multiband antenna allows transmissions on the 40/20/15/10 meter bands. Center point is held up with masting and ends are secured to roof. Two VHF verticals are also ...
Antennas can be classified in various ways, and various writers organize the different aspects of antennas with different priorities, depending on whether their text is most focused on specific frequency bands; or antenna size, construction, and placement feasibility; or explicating principles of radio theory and engineering that underlie ...
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.
Louis Varney (G5RV) invented this antenna in 1946. [4] It is very popular in the United States. [5] The antenna can be erected as horizontal dipole, as sloper, or an inverted-V antenna. With a transmatch, (antenna tuner) it can operate on all HF amateur radio bands (3.5–30 MHz). [5] [6]
Many antennas [1] is a smart antenna technique which overcomes the performance limitation of single user multiple-input multiple-output (MIMO) techniques. In cellular communication , the maximum number of considered antennas for downlink is 2 and 4 to support 3GPP Long Term Evolution (LTE) and IMT Advanced requirements, respectively.
50–54 MHz: Amateur radio 6-meter band. 50.8–51 MHz: Radio-controlled aircraft (on ten fixed frequencies at 20 kHz spacing) with an FCC amateur radio Service license, flown under FCC Part 97, rule 97.215. [9] 54–88 MHz, known as "Band I" internationally; some DTV stations will appear here. See Pan-American television frequencies.
Radio amateurs can build the Hexbeam as a multi-band antenna to cover different frequency ranges. Popular combinations cover 20m, 15m and 10m (3 band) and 20m, 17m, 15m, 12m and 10m (5-band) ham radio bands. Hexbeams can also be built for the 40m and 30m bands. The antenna elements for the lowest frequency band are located at the exterior of ...
