Uniden SDS100 BNC/SMA adapter Review

THE SHORT VERSION

Our verdict

This adapter is useful when a suitable antenna has a BNC connection and the scanner needs the corresponding SMA-side fit. Its job is mechanical and electrical connection, not signal amplification. Uniden identifies SDS100 and SDS150 for this part, which is more useful than selecting a generic adapter solely from a photograph. Before buying, establish the antenna's band, the connector genders and whether the complete assembly will fit comfortably around the radio. The adapter should solve a defined connection problem.

A good fit for

SDS100 or SDS150 owners with a suitable BNC antenna

Consider something else if

You expect an adapter to improve reception by itself

Reasons to consider it

Specific scanner-fit listing
Allows alternative antenna arrangements
Small replacement or spare part

Trade-offs to know

Adds a mechanical connection
No added frequency or decoding support

AT A GLANCE

The important details

Fit: SDS100; SDS150
Part: BYYG1687001
Purpose: BNC antenna to scanner SMA connection

Specifications are drawn from the linked documentation. Confirm the exact model, current firmware and included accessories with the manufacturer before purchase.

Fit and function

Uniden lists BYYG1687001 for connecting BNC-type antenna arrangements to the SDS100 or SDS150. Its fit should not be generalized to every SMA-equipped scanner because surrounding clearances and the exact connector arrangement can differ. No reception gain is attributed to the adapter itself.

The buying decision

A long rigid adapter-and-antenna stack can place an inconvenient lever above a handheld receiver. Consider the physical arrangement and cable strain as well as whether the connectors mate. If you already have the correct supplied adapter, another is a spare rather than a performance upgrade. Be wary of using several stacked adapters simply because each is inexpensive. A properly matched antenna cable can be a cleaner answer for a fixed installation. Check the whole connection route from antenna to radio before placing an order.
