Before construction, it is highly recommended to use antenna modeling software such as or MMANA-GAL . These tools allow the operator to visualize the pattern and adjust dimensions for specific wire gauges and heights above ground.
While "hot" links for direct PDF downloads often lead to unreliable sites, you can access the full text through legitimate digital libraries:
| Antenna | Gain (dBi) | F/B (dB) | Size (% of Yagi) | Build complexity | |---------|------------|----------|------------------|------------------| | Dipole | 2.15 | 0 | 50% | Very low | | 2-el Yagi | 5.0 | 15 | 70% | Medium | | | 5.5 | 25 | 60% | Low | | 3-el Yagi | 7.5 | 20 | 100% | High |
: Recognizing that wire is the most cost-effective material, the book provides extensive details on optimizing wire-based arrays for limited spaces.
, is the definitive guide for radio amateurs dealing with restricted spaces or specific environmental challenges. Amazon.com Summary of the Moxon Rectangle
Named after Les Moxon, G6XN, this antenna is essentially a two-element Yagi with a twist—literally. By folding the ends of the driven element and the reflector toward each other, you achieve several massive benefits:
