Comet Dual-Band HT Antennas CH-32 - Compact 2M/70CM Handheld Antenna

In this review the Comet CH-32 is evaluated as a compact, dual-band handheld transceiver antenna aimed at amateur radio operators who need a portable, reliable antenna for VHF and UHF use. The bottom line: it is best for users who want a simple, durable upgrade from stock rubber ducks and a modest gain improvement on 2M and 70CM bands without adding bulk. The CH-32 delivers predictable performance, a flexible whip with base coil, and common connector options that make it a straightforward fit for many handheld transceivers.

Key Features

• Dual-band coverage: Covers the 2M (144-148 MHz) and 70CM (430-450 MHz) amateur bands so users can operate VHF and UHF without switching antennas.
• Improved gain: With approximately 2.15 dBi on VHF and 3.4 dBi on UHF, the CH-32 offers better signal pickup and transmission than most stock handheld antennas.
• Flexible construction: The whip and base coil provide durability for field use and resist breakage during routine portable operations.
• Portable length: At about 13 in (33 cm) it remains compact for handheld carry while still providing useful radiation performance compared with shorter designs.
• Common connectors: Available with popular connector types (BNC, SMA male, etc.), making it compatible with a wide range of handheld transceivers without adapters in many cases.
• Low power handling: Rated to 10 watts maximum input, suitable for typical handheld radio output levels used by most amateur operators.

Who It's For

The CH-32 is aimed at amateur operators and hobbyists who use dual-band handheld radios and want a compact, higher-performing alternative to stock antennas for everyday portable or mobile use. It is especially useful for net participants, beginners upgrading their radio, and operators who carry a radio while hiking or traveling.

Those who routinely require high-power or specialized directional performance should look elsewhere, as the CH-32 is designed for handheld power levels and omnidirectional operation rather than base-station or high-gain fixed installations.

Pros & Cons

Pros

• Noticeable gain improvement on both 2M and 70CM compared with typical stock handheld antennas.
• Compact 13 in length balances portability and performance for mobile and field use.
• Durable flexible whip with base coil resists damage from everyday handling.
• Multiple connector options increase direct compatibility with common HTs.

Cons

• Maximum power input of 10 watts limits use to handheld-level transmitters and small mobile installations.
• Not intended for high-gain base-station performance or directional needs.
