10 Turn each radial element into radial

element holders. Then align water

drain hole in each radial element trap

coil assembly downward by turning

backward and fasten each element

with grip nut, Note that 6m radial

element does not have trap coil assem-

bly. (Refer to Fig-9)

<<Note>>

To avoid breaking each radial element

trap coil assembly, turn it into a holder

lightly till it stops and turn backward to

align water drain hole downward and

secure with a screw.

●Adjustment

<<Note for frequency adjustment>>

Practice

the

following

procedure at the place where the antenna

is actually installed.

Test transmission for the adjustment has

to be performed for as short time as

possible and with as low RF power as

possible. Maximum RF power rating of

continuous wave.

(CW or FM at less than 10W)

1 Prepare suitable VSWR meter for

operating frequencies and output RF

power. Then connect it as shown in

below.

meter

2 Adjustment procedure can be started

from any frequency you like. Transmit

at desired frequency and trim adjust-

ment length of radial element to have

lower VSWR at the frequency.

Adjustment length of each radial element

is shown in the following table. If you do

not have a VSWR meter, adjust it to a

typical adjustment length.

※If the radial element of a band is made

longer, resonant frequency of the band

is made lower proportionally.

※Though typical adjustment length of

each radial element is set at center

frequency of each band, it varies more

or less depending on the place the

antenna is installed.

Adjustment example:

If center frequency of 40m band is set at

7.050MHz and real center frequency

when the antenna is installed is at

7.010MHz, then frequency difference

between is:

7.050MHz (desired center frequency) –

7.010MHz (real center frequency) =

40KHz.

From Table A, adjustment length at 40m

band

adjustment

therefore:

10mm x 40KHz / 10KHz = 40mm

Since real center frequency is lower than

desired center frequency, radial element

has to be made 40mm shorter to have

7.050MHz center frequency.
