Antennas : 160M
  • 160 Meter Ground Plane - The 160 meter ground plane is constructed from #10 stranded insulated wire available in most hardware stores. The feedpoints / tiepoints use PVC pipe T-sections Article by W1TR

Antennas : 40M : 40 meter Vertical Antennas
  • 40m Vertical End-Fed Antenna - A quarter wave vertical end-fed antenna for the 40 meters band. As all vertical antennas, also this aerial requires a good earthing system. In this project the ground is composed by twelve 4, wires buried in the lawn by using a spade to create a slit to drop the wire into.

Antennas : Four Square
  • 40 m Wire 4 Square Vertical Array - 40 meter four square vertical array using four full-size 40 meter ground plane antennas, using only two radials

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 : Installation
  • Broadcast Antennas on Buildings - When a broadcast antenna is to be placed on top of a building, there are special problems of feeding and grounding. The radiator is usually electrically short, that is, much less than one-quarter wavelength high.

Antennas : Longwave
  • Notes on Designing LF-MF antennas - A free book on designign LF MF antennas. The six chapters in the body of the book are limited to basic information which, combined with a little modeling or simple calculations, can be applied directly using graphs for special problems like inductor design.

Antennas : Portable Antennas : Receiving
  • Double Half-Delta Loop RX Antenna - This wire antenna was developed to offer for a small, low-band, ground independent directional receiving antenna, it requires only two support poles. It is basically composed by two interconnected half delta loops and is better than a single flag or EWE, and almost as good as two phased EWE in the same space.

Antennas : VHF UHF
  • Ground plane for 144, 222 and 440 MHz - Here we have a ground plane antenna mostly used for 144, 222, 440 Mhz. Its one of the simplest antennas to make. New hams can build this with little to no experience in antenna building.
