Antennas : 160M
  • 160M Folded Counterpoise - An FCP is not magic. It has no gain. An FCP improves an antenna system by replacing more loss with less loss. Some have been able to erect better wires in the air because the small size of the FCP allowed better placement of the antenna.

Antennas : 40M : 40 meter Delta Loop Antennas
  • Delta Loop DX Antenna for 40 meters band - A monoband delta loop antenna for the 7 MHz. This vertically polarized DX Antenna is a full wavelength sngle side antenna and has a total length of 42.3 meters (137,1 inch) Can be easily setup with a flag pole or fishing pole as center top mast. For optimal performance lower side should be at 2 meter above the ground. This antenna offers a low radiation angle and 1 DB Gain.

Antennas : 70cm
  • Coaxial Collinear Antenna for 70 CM Band - This coaxial collinear antenna was built to test for my own consumption whether or not this antenna method actually works. the guiding principle is that we have multiple 1/4 wave elements fed in series , the radiation from each adds in phase to produce a large vertically polarised omni-directional antenna with substantial gain

Antennas : HexBeam
  • HexBeam Antenna Explained - A hexagonal beam is a form of the Yagi antenna which is based on parasitic principles developed early in the last century in Japan for achieving gain in one direction.How HexBeam antennas works. A hexagonal beam operates exactly like Yagi antenna, but instead of a driven element that is straight like a dipole, it is a wire bent into the shape of the letter M.

Antennas : J-Pole
  • Exploring The J-Pole Antenna - The J-Pole antenna is a common omnidirectional antenna used in amateur radio, particularly on the VHF and UHF bands. This article is an attempt to explore how the J-pole antenna transforms feed-line impedance to free-space impedance, all the while providing gain found only in the more expensive commercial products.

  • Improving Gain of the Super J-Pole Antenna - The collinear J-Pole, often known as the Super-J, does improve the behavior over a regular J-Pole. there is an advantage when vertically combining 1/2 radiating sections to have a bit of separation between the half-wave end points. Get 0.8 dB more gain out of the trusty Super-J by replacing the traditional phasing stub with a long coil.

Antennas : Theory
  • The Yagi Antenna - Presentation - A presentation of the Yagi Antennas, and other interesting tid-bits by Brian Mileshosky. This document explains basic concepts of Yagi-Uda antenna theory, influence of reflector and directors on global antenna gain and directivity of radio waves. A simple tape measure antenna project is also included.

Antennas : Vertical
  • Homebrew 5/8 Wave HF Vertical Antennas - The advantage of 5/8 wave antenna is that it has the lowest angle of radiation and has about 1dB more gain when compared to 1/4 and 1/2 verticals. So the 5/8 should be the favourite choice for DX.

Antennas : Wire
  • Lazy H Array Antenna for 40 meter - Make them simple then Make them work. The LAZY H antenna is a general type of antenna that is in the curtain array family. By placing two 1 wavelength dipoles in a plane that is at right angles to the direction of maximum radiation and keeping the proper in-phase current condition to each element, you can achieve a high gain bi-directional antenna.
