2.4 GHz Wireless Data Transceivers
LIG0002AC Rev G
The following table demonstrates how the Transmit Power parameter setting on the transceiver corresponds
to the EIRP indBm with the transceiver-cable-antenna combination for a 4 dBi Yagi antenna at different cable
losses in a Point-to-MultiPoint or Point-to-Point network.
Note: ETSI regulations allow only 20 dBm.
Networks with 4.0 dbi Yagi Antenna
Cable Loss
Transmit Power
1 dB 2 dB 3 dB 4 dB
27 30 29 28 27
26 29 28 27 26
25 28 27 26 25
24 27 26 25 24
23 26 25 24 23
22 25 24 23 22
21 24 23 22 21
20 23 22 21 20
Note: Networks using 2.4 GHz transceivers exclusively for fixed, Point-to-Point
operation may employ transmitting antennas with directional gain greater than
6dBi, provided the maximum peak output power of the intentional radiator is
reduced by 1 dB for every 2 dB that the directional gain of the antenna exceeds
6dBi.
This excludes the use of a Point-to-MultiPoint system, omni-directional
applications, or multiple co-located intentional radiators transmitting the same
information.
Waterproofing External Connections
After you have installed all the components at the site, waterproof all exterior connections with a moldable
plastic coax sealant or using mastic tape and an electrical coating. Ensure that each connection in the
installations is thoroughly sealed.
Moldable coax sealant and other electronic waterproofing supplies are available at most electronic supply
stores. Follow the installation instructions provided with the product to ensure a proper waterproofed seal.
