The TZ-V-3 is a tri-band vertical antenna for the 10, 15 and 20m bands. The antenna is especially compact when dis-assembled for ease and lower cost of transport. It is quick to assemble, efficient for its size and has extremely good bandwidth covering the whole of each band with a VSWR less than 2.0:1. The antenna may also be used on 11m (HF CB) at the same time as 10m! (slightly lengthen the element with resulting higher VSWR above 29 MHz).
