## Overview

The Diamond Antenna BNCJ-SMAP Low Profile Black Adapter converts SMA male antenna ports on handheld radios to BNC female connectors, enabling versatile antenna compatibility. Its compact, low profile design minimizes mechanical stress on connectors, while the gold-plated center conductor ensures reliable conductivity and corrosion resistance. Maintaining a precise 50 ohm impedance, this adapter supports superior RF performance across VHF and UHF bands, making it ideal for amateur radio, scanning, and public safety communications. Finished in sleek black, it offers a professional look and durable build for field, mobile, or bench use.

## Description

The Diamond Antenna BNCJ‑SMAP Low Profile Black Adapter is a precision RF connector adapter that allows handheld transceivers with SMA male antenna connectors to interface directly with BNC female‑terminated antennas, coax leads, or accessory cables. This professional‑grade adapter solves a common compatibility challenge faced by amateur radio enthusiasts, scanner operators, and communications technicians who wish to use legacy or specialized BNC antennas with modern radios that typically employ SMA interfaces. Featuring a low profile design and a robust base that sits flush against the body of the handheld radio, the BNCJ‑SMAP reduces mechanical leverage on the SMA connector. This minimizes stress during installation and removal of antennas and accessories — an especially useful feature when working in mobile or field conditions where gear is frequently changed. The 50 ohm adapter maintains impedance continuity between connected components, helping to preserve signal quality and reduce reflection or mismatch issues that can arise when using lower‑quality interfaces. Its gold‑plated center conductor enhances conductivity and provides corrosion resistance for long service life, while the sturdy metal body withstands repeated connect/disconnect cycles. Small yet versatile, the BNCJ‑SMAP Adapter is suitable for connecting handheld transceivers to mobile antennas, whip antennas, magnetic bases, coax jumps, and test equipment that use BNC terminations. It also supports a variety of RF tasks including scanning, monitoring, and portable communications where flexible antenna options are desired. Whether you are upgrading your handheld rig, adapting to an existing antenna setup, or experimenting with different antenna configurations, this adapter is a practical and cost‑effective accessory. The black finish provides a sleek, unobtrusive addition to your gear bag and matches well with most handheld radios and accessories.

Review: Superior fit and electrical connection, worth the upgrade in price - Simply the best BNC SMA adapter made. It's tight at first, but that's what makes it good. No slop or movement, great electrical connection and vastly superior to the other off name brands I've tried.
Review: Perfect for Yaesu - Bought for my Yaesu. Great fit, fills up the gap between the connector and case of the radio.

### ⭐⭐⭐⭐⭐ Superior fit and electrical connection, worth the upgrade in price
*by A***C on August 2, 2025*

Simply the best BNC SMA adapter made. It's tight at first, but that's what makes it good. No slop or movement, great electrical connection and vastly superior to the other off name brands I've tried.

### ⭐⭐⭐⭐⭐ Perfect for Yaesu
*by J***S on September 20, 2025*

Bought for my Yaesu. Great fit, fills up the gap between the connector and case of the radio.

### ⭐⭐⭐⭐⭐ Too short for Yaeusu VX-5r, but works great with adaptor ring.
*by L***N on February 6, 2025*

I did have to 3D print an adaptor for this to fit onto my Yaeusu Vx-5R, so if you are using it for that radio, know that the socket on the adapter is not deep enough for the rubber grommet to seat onto the radio. The male threaded screw post with the female SMA on the radio is very tall. Otherwise, this adaptor is great. A little stiff but after a few seat and reseats of an antennae, it works perfectly. Using with a Signal Stick.
