Antennas : Antenna Calculators
  • Helical Antenna Design Calculator  updated - Helical antennas invented by John Kraus give a circular polarized wave. They are one of the easiest to design. Find a tube with a circumference equal to one wavelength, and wrap wire in a helix spaced a quarter wavelengt

Antennas : Four Square
  • TX Four Square Antenna - A 220-ft tower that has five catenary lines, each about 500 feet long. Four of these lines, running NE, SE, SW, and NW support four 1/4-wavelength wire verticals used in a 160-meter four-square antenna.

Antennas : Homebrewing Techniques
  • Wire Antenna Design Lengths - The Classic Numbers for All Types of Wire Antennas at HF. Wire antennas need to be made a bit long and cut to resonance. They are affected by height above the ground and surrounding objects. In order to get an idea of the right place to start, certain formulas are generally accepted.

Antennas : Loop
  • Vertical Full Wavelength Loop - Consider installing a stealth vertical loop antenna if you live in a place with no antenna restrictions. Full wave loop wire antennas allow you to be on the air without installing evidente external aerials.

Antennas : Wire
  • Long wire antenna random wire - About longwire antennas, technically to be a true longwire an antenna needs to be at least one wavelength long, but common use of the term by Hams is for any random wire length that is end fed.
