Moxon for 144 Mhz
A portable 2-meter Moxon antenna with construction details and performance data.
Description
Details the construction of a portable Moxon antenna optimized for the 2-meter band, utilizing readily available materials like 6.5 mm aluminum elements and a 15x15 mm TV boom. The design emphasizes ease of assembly and portability, making it suitable for field operations.
Performance specifications derived from MMANA modeling indicate a forward gain of 6.3 dBi and a front-to-back ratio of 15 dB. Lateral attenuation is reported at 40 dB, with a minimum SWR of 1.1 at 144.300 MHz, confirming efficient operation within the target frequency segment.
The antenna is lightweight at 500 grams, quickly assembled in approximately two hours, and disassembles into a compact 40x15x8 cm package. Direct feeding with RG-58 C/U or KX-15 coaxial cable via a BNC connector simplifies deployment.
