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
