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.
F1UPS Radioamateur Antenne long fil (20 mètres) + balun 1/9 ITAMTFT
A multi-band super mini loop antenna. Posted in HF Antennas. Here's how to make the "Super" antenna. To build this antenna you need a lot that is at least 100 feet across. (This can be on a diagonal). Antenna covers all bands 80-10 meters + 30, 17, 12 meter WARC Bands. This antenna works as a Full Wave Loop on 80 Meters and also works as.

DELTA LOOP Antenna MULTIBAND HF 1 kW VERSION in Newport Gumtree
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.

Here, we'll follow the 'Apex Up' route as we plan to use the tower to support the apex of a wire loop and subsequently feed the loop either on the side, at any lower corner or on the horizontal base wire.The horizontal base wire of the loop is about 2m above ground. The loop has three wires, 27m on each leg. The modelling reflects this although the builder could stray from the.

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.

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.

Les différentes bandes sont parfaits pour parler aux opérateurs de radio amateur (jambons) à des distances différentes, différents moments de la journée, les saisons différentes et à différents.
MLA Loop Antenna BTV
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.
