Comet SMA-W100RX2 Telescopic Antenna - Wide Band Receiver

In this review the Comet SMA-W100RX2 is evaluated as a practical replacement handheld antenna for scanners with an SMA connector. Its single biggest reason to buy is the combination of broad receive coverage from 25MHz to 1300MHz and a marked telescoping element that helps tune reception for specific bands, making it useful for hobbyists and professionals who need a compact, adjustable antenna. The reviewer found it easy to fit, durable in routine use, and noticeably better in reception compared with stock portable scanner antennas.

Key Features

• Wide receive range: Covers 25MHz to 1300MHz so one antenna handles many common VHF/UHF scanner bands without swapping elements.
• SMA male connector: Directly fits handheld scanners with an SMA jack for a secure connection and straightforward replacement.
• Marked telescoping element: Telescoping sections are stamped with lengths so users can extend and tune the antenna to optimize receive at particular frequencies.
• Rotatable element and double hinge: The rotatable tip and double fold-over hinge add convenience for storage and positioning when space is limited.
• Compact storage length: Collapses to 8 in for pocket or bag carry and extends to 40 in when greater gain is needed.

Who It's For

The Comet SMA-W100RX2 is aimed at scanner owners who want a clear, simple upgrade over stock telescopic antennas, including radio hobbyists, field reporters, and anyone who needs broad receive coverage from HF-adjacent VHF through UHF. Its marked telescoping sections make it especially useful for users who like to fine-tune the antenna length for particular frequency ranges.

Those who need an antenna for transmit use, or are looking for a specialized directional or mountable base antenna for fixed installations should look elsewhere. This model is dedicated to receive/scanner use and is optimized for handheld convenience rather than station-mounted performance.

Pros & Cons

Pros

• Good overall reception across a wide band, with multiple customers noting improved signal pickup versus stock antennas.
• Wide frequency coverage eliminates the need for multiple quick-swap antennas for common scanner listening.
• Telescoping element marked for easy length adjustments to optimize reception at targeted frequencies.
• Folds down to a compact 8 in and extends to 40 in for flexible use and transport.

Cons

• The double fold-over hinge and rotatable element are convenient but the hinge does not swivel a full 360 degrees, which some users expected.
• As a handheld receive antenna it is not a substitute for larger external or directional antennas when maximum range is required.

Specifications

Our Verdict

The Comet SMA-W100RX2 is a sensible, good-value receive antenna for handheld scanner users who want wider frequency coverage and easier tuning than many stock antennas provide. It balances compact storage and practical receive performance, making it a recommended upgrade for hobbyists and field users, while fixed-station users should opt for a larger external antenna.

Frequently Asked Questions

Will this antenna fit my handheld scanner?
It fits scanners with an SMA female jack because it uses an SMA male connector.

Can this antenna be used for transmitting?
This model is described as a dedicated receive/scanner antenna and is intended for receive use; it is not specified as a transmit base for station use.

How do I optimize reception for a specific frequency?
Extend the telescoping element to the marked length closest to the target frequency and adjust incrementally while listening for the best signal.
