172-4H-MK

Overview

The 172-4H-MK is a heavy-duty Yagi antenna manufactured by Antenna Technologies Limited Company, designed for VHF applications below 300 MHz. It operates at a center frequency of 172 MHz with a bandwidth spanning 168 MHz to 176 MHz. The unit features a 4-element configuration providing 7 dBi gain and maintains a voltage standing wave ratio (VSWR) of 1.2. Termination is provided via an N-type female connector, suitable for robust wireless communication setups.

Feature Summary

• Heavy-duty construction optimized for demanding environments
• Four-element Yagi design ensures directional signal transmission
• N-type female termination facilitates standard cable integration

Applications

• VHF wireless communication systems
• Defense wireless applications
• Commercial enterprise radio networks

Procurement Notes

Verify the specific suffix MK indicates the inclusion of a mounting kit as per manufacturer documentation. Confirm that the N-type female interface matches existing cabling infrastructure. Ensure operational frequency aligns with the 168–176 MHz range to maintain optimal performance and impedance matching.

Selection Notes

Select this model when high-gain directional coverage is required in the VHF band. The heavy-duty build suits outdoor or industrial installations. Compare against other Yagi variants if different gain levels or connector types are necessary for the specific network topology.

Part Context

This component belongs to the 172-4H series from Antenna Technologies Limited Company, a specialist in commercial and defense wireless solutions. The MK suffix typically denotes a mount kit variant, distinguishing it from the base antenna unit while retaining identical RF characteristics.

Replacement Considerations

Direct substitutes include the 172-4H base model if mounting hardware is sourced separately. Cross-reference with other 172 MHz VHF Yagi antennas from the same manufacturer to ensure mechanical compatibility and identical electrical specifications.
