MHBDC5800

Antennas RF Overview

The MHBDC5800 is a VHF mobile whip antenna manufactured by Amphenol PCTEL. It operates within the 142–174 MHz frequency range, with a center frequency of 159 MHz and a usable bandwidth of 6 MHz. The component provides 3 dB gain and features a DC grounded base-loaded 5/8 wave design. This configuration requires less ground plane than conventional antennas while achieving lower VSWR. The unit is field-tunable and utilizes a straight base mount.

Antennas RF Procurement Notes

Verify the specific ordering suffix against the manufacturer's current catalog to ensure correct polarization and connector type. Confirm that the DC grounded specification aligns with the vehicle chassis grounding scheme. Check for any recent revisions to the mechanical dimensions or mounting hardware included in the package.

Antennas RF Selection Notes

Select this model when a compact VHF solution with reduced ground plane dependency is required. The field-tunable capability allows for fine-frequency adjustments during installation. Ensure the operating environment supports the 142–174 MHz band and that the vehicle chassis can provide an effective DC ground connection.

Antennas RF Part Context

This part belongs to the MHB series of mobile antennas from Amphenol PCTEL. The series focuses on VHF applications requiring reliable performance in space-constrained environments. The MHBDC5800 specifically addresses the need for efficient radiation patterns without extensive metal ground planes.

Antennas RF Replacement Considerations

Direct substitutes include other models within the MHB series offering similar VHF coverage. Verify that replacement units maintain the DC grounded base load characteristic and compatible mounting interface.
