Antennas : 2M

  • Budget-Friendly 5-Element Quad Antenna Design  updated - Constructing a 5-element quad antenna, the author aimed for low cost and simplicity, resulting in an effective design with 11 dBi gain and SWR of 2:1 or better across the 2-meter band. Using wood and dowels, the antenna costs under $8 and takes less than two hours to build with basic tools. The model predicts excellent performance, confirmed by ARRL Lab measurements. Practical field results demonstrate improved communication, even in simplex mode.

Antennas : Feed Lines
  • SWR: Maximum allowable VSWR - VSWR (voltage-standing-wave-ratio) represents the degree with which an antenna is "matched" to the system impedance. Most modern antennas do not require any tuning for optimum performance. VSWR is one of the easiest parameters to measure and VSWR meters are becoming very popular antenna installation tools

Antennas : Magnetic Loop
  • Magnetic Loop 600 KHz-4MHz - The antenna is built on a cross-shaped frame with spar width (and height) of 48 inches, providing a height of 52 inches and a width of 49 inches. This antenna costs only about $45 to construct and can be built in just a few hours using simple hand tools. The best part is that the performance on 160M and 80M is excellent
