The circuit board and jumper headers will be visible as shown in
Figure 7
.
The
AVA-2
has five
internal jumpers that modify frequency versus gain response. The L jumpers change the inductance
values and C jumpers change the capacitance values. As shipped, all jumpers are deactivated.
Figure 7 - Low Frequency
Jumper locations & Settings
Installing jumpers in L1MF, L1HF or both, will configure the antenna for a sensitivity peak near the
frequencies listed in
Figure 7
. The frequency response above the peak frequency does not change
significantly. Below the peak frequency, sensitivity reduction is reasonably fast. Installing a jumper
in any C1 position when jumpers are being used in L1 will move the peak response lower in
frequency, decreasing sensitivity at higher frequencies.
Alternate Mounting
If you plan to mount the
DXE-ARAV3
to a
larger mounting mast, two optional
DXE-
SSVC-150P
and one optional
DXE-SSVC-
150PG
V-Clamps are required which will
accommodate mounting pipes from 1" OD to 1-
1/2" OD. Refer to
Figure 8
for examples.
