FG8243

Antennas RF Overview

The TE Connectivity FG8243 is a fiberglass omnidirectional whip antenna designed for the 824 MHz to 896 MHz frequency band, with a center frequency of 835 MHz. It provides a gain of 3 dBd and supports a maximum power rating of 100 W. The unit features an N-type female connector and utilizes bracket mounting. Key electrical specifications include a VSWR of 2:1 and 50 Ohms impedance. Physically, it measures 635 mm in height and operates within a temperature range of -40°C to +85°C.

Antennas RF Feature Summary

• Omnidirectional radiation pattern suitable for broad coverage applications
• Constructed from durable fiberglass material for outdoor durability
• Direct N-type female termination for straightforward cable connection

Antennas RF Applications

• Public safety agency communications
• Commercial organization radio systems
• Military communication networks

Antennas RF Procurement Notes

Verify the specific datasheet version when ordering, as recent engineering change notices regarding base tube diameter changes may affect physical dimensions or compatibility. Confirm that the required mounting hardware, such as clamps, is included or ordered separately, as they are often sold independently. Ensure the application environment stays within the specified temperature and wind velocity limits.

Antennas RF Selection Notes

Select this model when a 3 dBd gain is sufficient for the link budget within the 824-896 MHz band. Compare against the FG8240 (0 dBd) if lower gain is acceptable, or the FG8246 (6 dBd) if higher directivity is needed. Ensure the N-type female interface matches the existing feed line connectors. Verify that the bracket mount style fits the installation structure constraints.

Antennas RF Part Context

The FG8243 belongs to the TE Connectivity FG series of outdoor cellular antennas. This series covers various gain options for the same frequency band, allowing system designers to balance coverage area and signal strength. It is part of the broader portfolio supporting GSM, LTE, and other cellular standards in the UHF spectrum.

Antennas RF Replacement Considerations

The Q9937477 is listed as an alias for this component. Direct substitutes within the same family include the FG8240 and FG8246, which share the same frequency range and form factor but differ in gain specifications.
