Boobrie Upgraded RP-SMA Male to RP-SMA Female 1m RG58/U coaxial extension cable
Product description
At a glance
This Boobrie RP-SMA male to RP-SMA female coaxial cable is a 1m “bulkhead extension” style lead designed to move your WiFi aerial connection where the original cable reach simply isn’t enough. Over the same sort of setups where you’d use an external antenna on a wireless PCIe network card, a USB WiFi adapter, a router, or a wireless bridge, it gives you a straightforward way to reposition the antenna for better placement.
On paper, the point of this cable is signal stability and durability rather than flashy features. It uses an “upgraded” RG58/U build with a reverse polarity SMA male on one end and a reverse polarity SMA female on the other, and it’s stated to be low-loss with 50±2 ohms impedance.

What you’ll notice day to day
The practical benefit of a coax extension like this is placement. If your current WiFi antenna ends up behind furniture, inside a cabinet, or too close to the router body, a longer or repositioned run can help you get a more sensible antenna angle and line-of-sight.


A quick example: imagine installing a wireless network card in a PC that’s not near the external antenna location you want. Instead of forcing the antenna right next to the case, you can route the coax along the back and mount the antenna where the signal seems less blocked—then use this 1m extension to bridge the gap.

That said, cable extensions are always a compromise. Even with “low-loss” claims, adding length can introduce attenuation compared to a shorter, direct run—so it’s best used when you actually need the reach for sensible placement.
Where it shines (and where it doesn’t)
This cable leans towards reliability and weather tolerance. The outer jacket is described as abrasion-resistant PVC, intended for normal service indoor and outdoor under extreme weather, with protection against wind, sand, moisture, and corrosion. If you plan to route the coax near doors, windows, or outside runs, the stated construction is at least aligned with that job.
Where it may not be the best fit is if your goal is absolute maximum performance with the shortest possible link. If you’re trying to squeeze every last bit of signal out of a system, a shorter cable or a setup with minimal extra length usually makes more sense. Also, if your connectors don’t match RP-SMA reverse polarity (not standard SMA), this won’t plug in as-is—so connector type is the first thing to double-check.

Who it’s for
It’s a sensible choice if: - you need a 1m RP-SMA extension to reposition an external aerial - you’re building or upgrading a wireless LAN setup where the antenna needs moving rather than the card/router - you want a coax cable aimed at durability, with a military-spec RG58/U approach described in the listing


It may not suit you if: - your antenna or equipment uses a different connector type (for example, standard SMA rather than RP-SMA) - you don’t actually need extra length and would rather avoid any added attenuation - you’re expecting miracles from an extension alone—placement helps, but it can’t fix issues like incompatible hardware or major obstructions
Care and practical tips

Because this is described as suitable for indoor and outdoor service, it’s generally more forgiving for typical home routing. Still, it’s worth thinking about strain relief and how the cable exits a case or mounting point. Avoid sharp bends where possible, keep the coax jacket protected from rubbing, and route it away from places where wind or grit might continuously abrade it.
Also, before ordering, confirm you’re matching both ends: RP-SMA male to RP-SMA female is a specific pairing. If either side on your equipment is different, you may end up needing an adapter instead.
Is it worth it?
Buying this Boobrie RP-SMA male to RP-SMA female 1m RG58/U extension cable makes sense if your main problem is antenna positioning and you need a compatible reverse polarity SMA lead to bridge a short gap. The stated low-loss, 50±2 ohms impedance and durable PVC jacket suggest it’s built to be used, not just stored.

However, if you’re trying to maximise performance without adding any extra length, or if you’re not sure your equipment truly uses RP-SMA reverse polarity at both ends, it might be a frustrating purchase. In those cases, it’s better to focus on the correct connector type first and keep the total coax run as short as practical.


Mini FAQ
FAQ
Will this work with a standard SMA connector?

The listing specifies RP-SMA (reverse polarity) male and female connectors. If your device uses standard SMA instead, you should assume it won’t be a direct fit.
Is 1m a lot for WiFi performance?
It’s not a huge amount, but it’s still extra length. Even with “low-loss” cable, added attenuation can happen—so it’s most sensible when you need the reach for better antenna placement.
What equipment is it intended for?
The description mentions wireless LAN and card setups, wireless router and bridge use, and external antenna equipment such as WiFi antennas and wireless video/IP security cameras—so it’s aimed at typical WiFi aerial extension scenarios.
What’s included?
You get one piece of the RP-SMA male to RP-SMA female upgraded RG58/U coaxial antenna extension cable, 1m in length.
