Caution
Connect the antenna and extension cable securely.
If water enters the pre-amplifier through the connectors for the antenna and extension cable, it may
cause a serious failure.
If you do not connect the antenna and extension cable, cover the connectors with the supplied caps to
ensure waterproofness.
(3) Installation of antennas
In general, the higher the antenna is installed, the
more vulnerable the signal is to radio interference.
Position the antennas and extension cables on the
ground whenever possible.
If the radio signal is not received well, use traffic
cone or some other stand etc. to mount a high-gain
antenna.
If the valve is deep and the antenna cannot be
extended to the ground, mount it on the pipe wall.
