Boobrie RP-SMA coaxial cable B-MR200

When a router’s antenna needs a little more room to reach a useful spot, a short extension can make positioning easier without replacing the antenna or router. The Boobrie B-MR200 cable connects an RP-SMA male end to an RP-SMA female end, giving you 3.28 ft of extra reach. That can help when the antenna is crowded behind equipment or blocked by where the router sits. The key is matching the connector type before you buy, RP-SMA and standard SMA are not interchangeable just because they look similar.

Where it shines

This is a coaxial extension for moving a compatible Wi-Fi antenna away from its device. For example, you could route the cable from a router tucked on a shelf and place its antenna nearer the shelf’s edge. The cable is listed as BMR200, equivalent to LMR200, with 50±2 ohms impedance. The product description positions it as a lower-loss alternative to RG58, particularly for wireless applications, but it doesn’t provide measured signal-loss figures. Treat that comparison as a stated product claim rather than a guaranteed improvement in your particular setup.

You’ll appreciate it if the antenna’s current position is the main obstacle and a short extension would let you place it more conveniently. If you prioritize a simple antenna repositioning, this is a more targeted choice than replacing networking equipment, if you prefer a longer cable run, its 3.28 ft length may not reach the location you have in mind.

What to know

The connectors are RP-SMA male to RP-SMA female. Check the connector on your router, antenna, or existing adapter carefully, including the reverse-polarity configuration, a similar-looking connector is not enough to confirm a match. The listing names uses including Wi-Fi routers, Wi-Fi IP security cameras, cellular modems, wireless video, and remote monitoring, but compatibility still depends on the device’s actual connector and setup.

The cable’s low-loss positioning is useful only if the rest of the connection is suitable. From the way it is set up, this is an extension cable, not an antenna, signal booster, or adapter for changing connector types. Its short length can help tidy a nearby placement, but it won’t solve a need to position an antenna across a room. The description does not specify weather resistance or installation hardware, so don’t assume either is included or intended.

Best use cases

Consider it when a compatible antenna needs to sit just outside a cramped space, or when you want to test a nearby alternative position without moving the router itself. A practical setup might be a wireless camera or router on a shelf, with the antenna shifted a short distance to avoid being pressed against the device or furniture. Results depend on the surrounding layout, and the listing does not quantify how much signal improvement to expect.

It’s not for you if you need a long extension, a different connector standard, or a documented performance figure for a specific installation. For a small adjustment, its male-to-female RP-SMA layout and stated 3.28 ft length are the details to match against your setup.

When it makes sense

This Boobrie cable makes sense when your equipment already uses RP-SMA and the antenna only needs a modest change in position. The BMR200/LMR200-equivalent construction and stated 50±2 ohms impedance give you useful selection details, while the RG58 comparison offers a reason to consider it over a basic RG58 extension. Choose it for a short, connector-matched repositioning—not as a fix for weak Wi-Fi by itself, or as a substitute for checking whether the antenna and router actually use RP-SMA.
