4GDPSM-W-1M Equivalent & Substitute Parts Reference

Part Overview

The 4GDPSM-W-1M is a multi-band dome RF antenna manufactured by PCTEL, Inc., designed for cellular and navigation applications. This antenna operates across three frequency bands (698MHz–960MHz, 1.575GHz–1.61GHz, 1.71GHz–2.7GHz) and features a 1-meter RG-174/U cable with SMA Male connector termination. The product is currently listed as Obsolete, making identification of compatible substitute parts essential for ongoing system support and component procurement.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 4GDPSM-W-1M is determined by the following critical parameters:

• Antenna Type & Form Factor: Both parts must be dome-type RF antennas with identical physical height (1.575"/40.00mm) to ensure mechanical compatibility in existing mounting configurations.
• Frequency Coverage: The substitute must support the primary frequency bands required by the application (698MHz–960MHz for LTE/cellular and 1.71GHz–2.7GHz for broadband LTE).
• Connector Type: SMA Male termination is required for direct compatibility with existing RF interfaces.
• Ingress Protection Rating: IP67 rating must be maintained to preserve environmental sealing specifications.
• VSWR Performance: VSWR of 2 or better ensures acceptable impedance matching across the operating frequency range.
• Manufacturer Consistency: PCTEL, Inc. maintains design and performance standards across the 4GDPSM series.

The substitute part 710682 meets these criteria while operating as an Active product with current manufacturing support.

Parameter Comparison

Engineering Selection Recommendations

The 710682 serves as a direct mechanical and electrical substitute for the 4GDPSM-W-1M in applications requiring LTE and cellular coverage across the 698MHz–960MHz and 1.71GHz–2.7GHz bands. Both antennas maintain identical physical dimensions, connector types, and environmental protection ratings, ensuring compatibility with existing RF interfaces and mounting structures.

The primary distinction is product status: the 4GDPSM-W-1M is Obsolete, while 710682 is Active with current manufacturing availability. For new designs or system replacements, 710682 is the recommended selection to ensure long-term component supply and support.

The 710682 operates with a 5-meter cable versus the 1-meter cable of the original part. This extended cable length accommodates installations requiring greater separation between the antenna and RF equipment. If the 1-meter cable length is a system requirement, cable length must be verified during integration planning.

The 710682 does not specify coverage of the 1.575GHz–1.61GHz GNSS band present in the 4GDPSM-W-1M. Applications requiring simultaneous GPS/GLONASS reception must confirm that GNSS functionality is not critical to system operation, or alternative antenna solutions must be evaluated.

Both parts maintain ROHS3 compliance and equivalent VSWR performance, supporting direct substitution in environmentally sealed installations.

Frequently Asked Questions (FAQ)

Q: Can the 710682 replace the 4GDPSM-W-1M in existing installations?

A: Yes, for applications requiring LTE and cellular coverage. Both antennas share identical mechanical form factors (1.575" height), connector types (SMA Male), and environmental ratings (IP67). The 710682 is electrically compatible across the shared frequency bands (698MHz–960MHz, 1.71GHz–2.7GHz). However, if GNSS reception (1.575GHz–1.61GHz) is required, system functionality must be re-evaluated.

Q: What is the impact of the extended 5-meter cable on the 710682?

A: The 5-meter cable provides greater installation flexibility for systems where the antenna must be positioned away from RF equipment. Cable length does not affect electrical performance if the cable is properly terminated and impedance-matched. System designers should verify that the extended cable length accommodates their physical layout requirements.

Q: Are both antennas RoHS compliant?

A: Yes. The 4GDPSM-W-1M is ROHS3 compliant. The 710682 inherits the same compliance standard as a member of the 4GDPSM series from PCTEL, Inc.

Q: Why is the 4GDPSM-W-1M listed as Obsolete?

A: Product obsolescence reflects manufacturing discontinuation. The 710682, as an Active product, represents the current generation of the 4GDPSM series and is the recommended selection for new procurements and system designs.

Q: What is the difference in gain specifications between the two antennas?

A: The 4GDPSM-W-1M specifies gains of -6.32dBi and -12.05dBi across its three bands. The 710682 specifies -6.32dBi and 12.05dBi across its two bands. Both antennas deliver equivalent performance across the shared LTE and cellular frequency ranges.
