Antenne Loop horizontale bibande VHF/UHF Komunica
Full Wave Horizontal Loop Antenna (a.k.a Skyloop) This antenna is horizontally polarized and should be mounted as high as possible but works well at low heights of 10-30 feet. They are quieter than a dipole or a vertical, have a broader bandwidth and will usually out perform a dipole antenna.To determine the approximate circumference in feet of.

LDF550 based Loop Antenna G4HSK loop antenna Pinterest 50th and Ham radio
Compact, Low height - vertically polarized DX antenna. Takes less space than dipole. (22 ft. At 21 MHz) Bottom wire at 12 ft is ~ optimum at 14 and 21 MHz. Clean low angle radiation patterns useful for DX. Omni radiation from 30m to 15m, somewhat directional on 10m. The rectangular loop has somewhat better patterns than the delta loop.

A "doublet" is a generic term for a dipole that is fed with low loss cable (typically parallel-conductor twinlead or open wire line with impedances of 300 - 600 ohms) and matched on multiple bands using an antenna tuner at the junction between the parallel-conductor line and the coax. The basic form of a doublet antenna.

SWR in the vicinity of 40m (the primary target band) with the loop cut to 537'. SWR in the vicinity of 80m. SWR in the vicinity of 20m. SWR curves in the vicinity of 40m. There is a minimum SWR point (off the left side of the graph) that winds up at about 7.175mhz, but which slowly moved up into the band as we cut the loop.

W5GI Mystery Antenna is a multi-band wire antenna that performs exceptionally well even though it confounds antenna modeling software. This antenna covers 80 to 6 meters with low feed point impedance and will work with most radios, with or without an antenna tuner. It is approximately 100 feet long, can handle the legal limit, and is easy and.

A multi-band HF loop antenna. Sat, 01/16/2010 - 00:49 — riel. Amateur radio has 10 HF (shortwave) bands, from 1.8 MHz (160 meters) through 28 MHz (10 meters). The different bands are great for talking to amateur radio operators (hams) at different distances, different times of the day, different seasons and different times during the solar cycle.
