Standard Horizon SMA to BNC adapter

The Standard Horizon SMA to BNC adapter (model CN-3) is a precision connector converter designed for radio operators and field technicians who need to mate Standard Horizon handheld transceivers with external antennas and communication systems equipped with BNC connectors. This compact adapter solves the compatibility challenge between the SMA connectors standard on Standard Horizon portable radios and the widespread BNC connector ecosystem used in professional and tactical communications equipment. Whether you're upgrading your antenna setup, integrating into a larger comms network, or extending your handheld's range and performance, this adapter provides a reliable, plug-and-play solution.

The Standard Horizon SMA to BNC adapter features precision-engineered connectors that maintain signal integrity while converting between the two connector types. The SMA (SubMiniature version A) interface on the Standard Horizon side provides a threaded, secure connection typical of compact handheld radios, while the BNC (Bayonet Neill-Concelman) side offers the quarter-turn locking mechanism favored in professional radio installations. The adapter's compact 1 x 1 x 1 inch form factor and lightweight 0.1 lb construction make it ideal for mobile operations, emergency response, or portable field setups. Proper connector matching ensures minimal signal loss and reliable impedance matching across VHF/UHF frequencies common to Standard Horizon equipment.

This adapter is essential for Standard Horizon handheld users who operate in professional environments—search and rescue, law enforcement, maritime, emergency management, and amateur radio—where BNC-equipped antennas, antenna tuners, amplifiers, or docking stations are standard infrastructure. Installation is straightforward: simply thread the SMA end onto your Standard Horizon radio's antenna connector and attach your BNC-equipped antenna or accessory to the opposite end. The CN-3 remains the original manufacturer part for this conversion, ensuring compatibility with all Standard Horizon portable transceiver models that utilize the standard SMA antenna port, making it an indispensable field accessory for expanding system flexibility.
