近日收购一条mfj1899t天线,817专用发射功率支持10w,说明书全是e文,各频段需要拉杆天线做伸缩,不知道怎么调整,以下是原文给位帮帮忙给翻译一下,
lengths of telescopics are for lowest freq.in band and with ground plane wire connected to radio .best length for ground plang plane wire
is less than 1/4 wave 180÷oreq(in nhz)=length in feet. telescopic can be adjusted for best vswr.
with no1 connected to no6 will also make reasonable 5/8 wave on 2mtr and airband.telescopic length on 2mtr┉approx45".telescopic length on airband┉approx50"
