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.

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.

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 "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.

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.
