Adaptor Cable: SMA Male to SO-239 to PL-239

Highest Quality Strain Relief Plus Connector Adaptor If you are using an existing antenna system, before you do, make sure the SWR is below 2:1 before connecting it to the MMX or DMX-40. This adaptor cable is designed to connect between the rear SMA female antenna connector on the MMX or DMX-40 and the standard antenna PL-239 plug. It also serves a second purpose, which is to reduce mechanical stress on both the PL-239 and its attachment to its likely stiff RF cable, and the very light and portable MMX with its PC-mounted SMA female connector. These cables are extremely well built, with multiple layers of sleeving to reduce the stress on the solder joints, in order to provide long life. At the SMA connector end, note the two-lawyer cable relief design. At the SO-239 end, a 3-layer cable relief design is used to compensate for the larger connector. In addition, a clear cap is provided to protect the internal surfaces of the connector when not in use. Keep an Extra on Hand! We suggest, a
