INTRODUCTION TO THE vk2iau allcoax multiband antenna
The vk2iau coax multiband antenna is an RG58U coax cable multi strand core antenna configuration of 4 interchangeable
components , as follows:
A: antenna A = INVERTED V DPLE = 2.15m long EITHER SIDE OF THE INV V DPLE APEX . coax cable outer
braid radiating elements in parallel , plus feedline coax to radio
B: antenna B = SINGLE 2.15m long coax cable outer braid radiating elements in series,
plus feedline coax to radio
C: 3.5 metre long shorted coax , AS A COIL , counterwound on a small plastic cable drum and held in place by cable ties , the drum is then
covered in aluminium foil which is independantly earthed , all of this is then covered in a nylon stocking to protect the aluminium foil.
D: 4 metre long shorted coax , AS A COIL , as above
Note: ALL EXPOSED PARTS ARE COVERED IN ‘ ROOF & GUTTER SILICON “ , which , when cured is wrapped in electrical
tape note: impedance at the radio is achieved fully or in part by COMBINATIONS OF THE 4 interchangeable components
( as described above ) , to utilise inductance / capacitance to extend the the " frequency time " longer than the " frequency
physical length time of the radiating elements " thus preventing the signal from hitting a brick walland bouncing back as unwanted SWR .
NOTE 1: I have found the antenna system COMPACT and excellent for TX and RX from my 6m boat
NOTE 2: The coax cable is laid on the roof tiles of my house , very inconspicuos , almost " secret " . COULD BE USED DIGUISED
AS A WASHING LINE

Civil 3D bukanlah AutoCAD biasa. Jika AutoCAD adalah pensil digital, Civil 3D adalah pensil pintar. Saat Anda menggambar garis jalan di Civil 3D, software ini secara otomatis menghitung volume galian/timbunan ( cut and fill ), kemiringan lereng ( slope ), dan elevasi. Data tersebut saling terhubung secara dinamis. Jika Anda mengubah satu titik, seluruh desain akan otomatis berubah. Civil 3D bukanlah AutoCAD biasa
