Chameleon Blank SO-239 SQUARE

The SQUARE SO-239 to SO-239 adapter is a precision-machined inline mounting and connection solution for amateur radio, field communications, and mobile antenna installs. Designed for operators who need a clean, modular way to join SO-239 equipped antennas or accessories to a standard 3/8″-24 mount, this adapter delivers strong mechanical support and efficient RF transfer in a compact format.

Overview

This adapter features two SO-239 female connectors and a 3/8″-24 male threaded base, making it ideal for antenna systems that need direct compatibility with common UHF-style connector hardware and standard threaded antenna mounts. It is well suited to portable deployments, mobile installations, bench testing, and modular station builds where quick equipment changes and dependable connections matter.

Key Features

Performance notes / setup guidance

For best results, use the adapter with quality coax, clean connector interfaces, and a mechanically stable mounting point. Verify that your mount uses a 3/8″-24 female thread before installation. This adapter is a connection and mounting interface, so final RF performance will depend on the antenna, feed line, grounding or radial system where applicable, and the overall installation environment.

If you need a durable SO-239 to SO-239 adapter for a 3/8″-24 antenna mount, this is a smart choice for building a cleaner, more flexible station or field kit. Add it to your setup and simplify your next portable, mobile, or fixed-station deployment.
