Rain Tree/Standpipe Install
If the ERTA2 is to be mounted in a Tree, there is an aluminium
accessory holder that allows the Radio and a battery to be housed on
the plate that can then be lowered into the tree enclosure similar to
the older Legacy cannister.
Tree bracket provide facility to restrain sensor cables, carry handle
and location to connect rope or carabiner to secure the unit inside the
rain tree.
Installation
Grounding
To provide maximum surge and lightning protection for antenna connection and sensor inputs, each
module should be effectively earthed/grounded via a GND terminal on the module. This is to ensure
that the surge protection circuits inside the module are effective.
If the ERT-A2 is to be mounted in an enclosure you need to ensure the enclosure ground and the
antenna mast/pole ground are connected to the same common ground point.
The ERT-A2 have a dedicated earth/ground connection M5mm screw on the side of the enclosure
for this Earth connection. All earth/ground wiring should be minimum 0.8 in2 (2 mm2), 14 AWG.
Earth screw MAX length is 8mm.

When installing the unit, it is important to ensure what all antenna cable
connections are waterproofed as water ingress into the cable will affect its
performance.
See below for recommend installation.
