Antennas : Baluns
  • Build your own HF balun - A balun is a MUST for dipoles or similar antennas when they are feed with coaxial cables. Many hams connect the center conductor of the coaxial cable to one side of the dipole, and the shield to the other. Wrong!

Antennas : Quad
  • 2 Meter 5 Element Quad - A five element quad antenna for 144 MHz DIY Project. This 2 Meter 5 Element Quad antenna was modeled using EZNEC, with a boom from a UHF TV antenna and CPVC pipe for spreaders. Constructed for 146MHz, it exhibits a gain of 10.7dB and an impedance of 75 ohms. Real-world results surpass the HT antenna, reaching over 20 repeaters up to 75 miles away. The design, costing around $10, employs simple tools for assembly.

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.
