Comet
Comet CH-32 (BNC)
This antenna trades range for size and charges a premium to do it. Unless a low-profile BNC stub is the specific goal, skip it.
Proprietary RR score
How we scored it
Performance is derived from the antenna's length in wavelengths on each band it covers, not from the advertised gain. How we score →
Length versus wavelength
What 44 mm Buys You
An antenna radiates according to its length measured in wavelengths, not according to the number on the packaging. Here is where this one lands on each band it covers.
| Band | Wavelength | This antenna | Works out as |
|---|---|---|---|
| VHF146 MHz | 2053 mm | 0.02 λ | electrically short |
| UHF435 MHz | 689 mm | 0.06 λ | electrically short |
Decision helper
Is this antenna right for you?
Yes, if you're…
- ✓BNC scanner users who specifically want the smallest possible stub
Skip it, if you're…
- ✕Anyone trying to improve range
- ✕Buyers comparing on value; cheaper stubs perform about the same
Tradeoffs
The good and the bad
What we like
- Extremely low profile, will not snag or catch
- Solid BNC connector build
What we don't
- Real-world gain is worse than a typical stock antenna on both bands
- Expensive for what it does
- Small review sample (34) to judge long-term reliability

Overview
The Comet CH-32 is a 1.75-inch stub antenna with a BNC connector, built for BNC-equipped scanners and handhelds such as Uniden and Whistler models rather than the SMA jacks most Baofeng-style radios use. At 44mm it is one of the shortest antennas in this catalog, and at around $39 it is also one of the more expensive.
The physics do not do this antenna any favors. At 44mm, it works out to roughly 0.02 wavelengths on 2m and 0.06 wavelengths on 70cm, both deep in electrically-short territory where the model predicts gain around -9 dBi and -5 dBi respectively. That is worse than most stock antennas, not an upgrade. The listing does not make a gain claim, which is at least honest, but the combination of a tiny element and a premium price makes this hard to recommend on performance alone. It exists for people who specifically need a low-profile BNC stub and are willing to trade range for it.
