External Antenna
The SPR model without a built-in antenna provides an N-type port for connecting a
third-party external antenna. The addition of an external antenna allows greater RF
sector coverage than the standard SPR built-in antenna models.
Warning: Before connecting the external antenna, ensure that the SPR is
NOT connected to the power source.
Warning: Before powering on the SPR, ensure that some type of equipment
such as an antenna or an RF attenuator is connected to the N-type receptacle.
This eliminates the risk of damaging the SPR device.
Warning: It is the responsibility of the person installing the ASWipLL system to
ensure that when using the outdoor antenna kits in the United States (or where
FCC rules apply), that only those antennas certified with the product are used.
The use of any antenna other than those certified with the product is expressl
y
forbidden in accordance with FCC rules CFR47 part 15.204. The installe
r
should configure the output power level of antennas according to countr
y
regulations and per antenna type.
Warning: In accordance with FCC regulations, ensure that for external
antennas, the maximum EIRP is 36 dBm. The EIRP is defined as:
Max. Power Output + Antenna Gain + Cable Loss ≤ 36 dBm (EIRP)
Notes:
1) SPR models that provide N-type connectors for attaching a third-party
external antenna do not contain an internal, built-in antenna.
2) It is recommended that the same antenna polarization (i.e. horizontal/
vertical) exists at both ends of the link (i.e. Base Station and subscriber site).
3) For crimping RF coaxial cables, see Appendix C, "Cable Crimping".
