1. 2m 70cm Dual X 200 Direct element joint structure with FRP shell Operating instructions Description Newly developed liner phase shifter permits to achieve two 5 8 wave length elements at 2m band and four 5 8 elements at 70 cm band in one vertical structure with outstand ing gain high power rating low vswr and broader band coverage at both bands Newly developed direct element joint struc ture with two interconnected FRP outer shells enables the antenna to maintain the same strength as one with one piece struc ture by it overlapping FRP outershells Perfect waterproof is achieved by the ring gasket The antenna can be easily assembled or disassembled by tightenning or losenning the joint bracket lightly 50 m sec 164 04 sec maximum wind resistance which exceeds professional anten na specifications is achieved Superior water proof structure avoids unstable vswr caused by climatic effect Rust and corrosion free structure permits the antenna to be installed at seaside or contaminated environment without any precautions Both of two bands 2 m and 70 cm can be2. 144MHz962 2 430MHz58A 4 144 MHz 430MHz N144 MHz 430MHz VSWR _ 2 CT 2 0 oon y OK 3 50m sec VSWR
