Tape Measure VHF antenna
Build a portable 2-meter VHF Yagi antenna using tape measure elements for RDF and satellite ops.
Description
A 7 dB directional gain is reported for this portable VHF Yagi antenna design, which utilizes cut metal tape measure sections for its elements. The resource details the construction process for a 2-meter band antenna, emphasizing its ease of build and portability. It specifically mentions the design's suitability for radio direction finding (RDF), fox hunting, and communication with satellites and the International Space Station (ISS), highlighting its practical applications for amateur radio operators.
The construction cost is estimated at under $20, with potential for even lower expense if salvaged materials like old tape measures and PVC pipes are used. The article references Joe Leggio's (WB2HOL) original design, noting specific alterations made by the author. It also compares this design to other DIY Yagi antennas, including FN64's 2-meter band and manuka's 70-cm band tape measure Yagis, underscoring its unique combination of simplicity, portability, and effective performance with a 1:1 SWR achievable on the 2-meter band.
