NSKI SRH805S SMA-F Female Dual Band Antenna - Compact Range Boost

Our review of the NSKI SRH805S antenna finds it is a practical, compact upgrade for handheld VHF/UHF radios that need a small, lighter replacement whip. The bottom line: if you want better range without adding bulk, this 5cm antenna delivers a measurable improvement thanks to its 2.15/3.0 dBi gain and support for up to 10 watts, while remaining tiny and easy to carry. It is sold in a 10-piece pack, which makes it useful for operators who maintain several radios or need spares.

Key Features

• Dual band VHF/UHF: Covers the common handheld bands so it works with 144/430MHz radios and many popular models with an SMA male interface.
• Compact length: At approximately 5cm the short whip is unobtrusive and ideal for tight pockets, backpacks, or belt-mounted radios.
• Reasonable gain: The 2.15 dBi on VHF and 3.0 dBi on UHF provide a noticeable range improvement over rubber duck antennas on handheld radios.
• SMA-F female connector: The standard SMA-F fitting allows direct replacement on radios that use an SMA male thread without adapters.
• Lightweight build: At about 20 grams each, these antennas add minimal weight to a handheld, preserving portability for field use.
• Pack of 10: Supplied in a 10-piece set, which is convenient for clubs, teams, or technicians who need multiple spare antennas.

Who It's For

The NSKI SRH805S is best for radio hobbyists, emergency communications volunteers, and technicians who need a compact replacement or spare antenna for handhelds that accept an SMA male connector. Its short length and light weight suit users who prioritize portability over a large rooftop-style antenna.

Those who regularly need maximum long-distance performance, rooftop mounting, or wideband professional antennas for base stations should look elsewhere, since this whip is designed for handheld convenience and mid-range improvements rather than extreme long-range or base-station use.

Pros & Cons

Pros

• Small form factor that keeps radios pocket-friendly while improving range compared with basic rubber ducks.
• Dual band coverage for 136-174MHz and 400-470MHz, matching common handheld frequencies.
• Standard SMA-F female connector for direct fit on devices with SMA male joints.
• Economical 10-piece package useful for multiple radios or replacements.

Cons

• Very short length limits gain compared with larger external antennas, so it is not a substitute for base-station antennas.
• Only available as the antenna; radios and adapters are not included.
