OTURA 3, broadband HF vertical antenna ITAANTENNAS
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.

Antenne Loop multibandes HF du 80 au 10m! Radio amateur a 10 HF (ondes courtes) bandes de 1,8 MHz (160 mètres) par 28 MHz (10 mètres). 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.
Counting Radios M0PLK Multiband Delta Loop Antenna
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.

This multiband antenna covers the 80, 40, 30, 20, 17, 15, 12, 10 and 6 Mx Amateur bands. Multiband operation is achieved by use of 300 ohm balanced line fed to an antenna tuner.
HF MAX10, broadband 1,870 MHz vertical antenna ITAANTENNAS
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.

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.

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.
