4-4 ADS RainAlert II Manual
Installing a Mini-wing or Slim Antenna
Secure the ruggedized mini-wing or slim antenna (ADS p/n 3800-
0162/0163 with SMA connector) to a wall, pole, or other structure
using cable ties, non-metallic clamps, or weather-resistant tape.
Extension cables (ADS p/n 507165 (15-foot) and other lengths) are
available when necessary. ADS also offers longer extension cables;
however, ADS recommends keeping cable length to a minimum to
prevent signal loss. Securely tape all connections to prevent
moisture access.
Once the antenna is installed, run the antenna cable to the monitor
location and connect it to the monitor. Refer to Modifying the
RainAlert II Monitor to Support an External Antenna on page 4-5
for detailed instructions.
Installing a Magnetic Whip Antenna
This installation involves securing a wireless whip antenna with a
magnetic base (ADS p/n 3800-0128) to a roof or other protected
magnetic structure. Roof or outdoor cabinet applications also
require a lightning protection device (ADS p/n 507180).
Mount the whip antenna in the following way:
Warning: Never place a magnetic mount antenna on top
of or near an office or field (laptop) computer. The strong
magnet in the antenna base will immediately corrupt the
computer’s hard drive.
1. Identify an anchored or heavy steel surface at least 4 inches by
4 inches to serve as the grounding plate.
2. If the whip antenna is not attached to the magnetic base, screw
the antenna onto the base using any sealing washers or o-rings
included in the packaging.
3. Seat the antenna base on the steel grounding plate surface
selected.
