Boobrie SMA Male to Female RG316 WiFi Antenna Extension Cable, 3m (Pack of 2)
Product description
If you’re trying to tidy up a weak or awkward wireless setup, a proper antenna extension can make more difference than you’d expect. This Boobrie SMA Male to SMA Female RG316 cable is designed to extend an SMA antenna run with low-loss coax, using a flexible RG316 build and gold-plated SMA connectors.
That said, it’s not a universal fix for every coax job. The SMA-to-SMA connector format is specific, and it’s not meant for TV use (so it won’t replace F-type cabling). If your goal is to get your WiFi/mobile modem antenna positioned where it can actually “see” the signal, this is the kind of practical accessory worth considering.
Key features
This is an SMA Male to SMA Female extension lead built around RG316 coaxial cable, supplied in a 3m length and sold as a pack of two. The cable is described as flexible and low loss, which matters when you’re carrying a high-frequency RF signal for wireless equipment.
On the connector side, the supplied SMA hardware uses copper with “great connectivity” (not an alloy), plus a gold-plated surface treatment. The package is aimed at people setting up router, WLAN/WiFi antenna, RF coax connectors, radios, and similar external antenna arrangements.
You also get a bit of durability reassurance in the wording: it’s described as having a mating life time of more than 1000 cycles. On paper, that’s the sort of figure you want if you expect to adjust positioning over time rather than fit it once and forget it.
What it’s for (and where it fits best)
This cable is primarily for extending SMA antenna connections—especially in WiFi, router, booster, WLAN and related RF setups. It’s mentioned for use with equipment like 4G LTE and 5G modem routers where antenna positioning can affect real-world coverage.
A concrete example: if your modem/router is in a cupboard or behind furniture and you want to move the antenna closer to a window or higher up, you can use the 3m lead to relocate the antenna while keeping the RF connection as straightforward as possible.
Worth noting that the description also highlights burial suitability and a wide temperature range (thanks to the PTFE dielectric). That doesn’t automatically mean you’ll bury every setup, but it does suggest the cable is intended to cope with less-than-ideal installation conditions.

Key takeaways on performance and limitations
The “low-loss” angle is the main reason you’d pick RG316 for antenna extension work like this, because coax losses can stack up with length. On paper, RG316’s PTFE dielectric and the flexible construction are intended to help keep the signal route consistent without turning installation into a chore.
However, there are two practical limitations you should bear in mind:
- It’s SMA-specific. If your device or existing antenna uses a different connector standard, this cable may not plug in the way you need.
- It’s not for TV. The listing is explicit that this SMA cable isn’t suitable for TV use—if you’re after an F-type TV coax setup, you’d need a different connector approach.
Getting the most from it
Most antenna extension cables succeed or fail based on fit and routing more than anything. Even with a low-loss cable, a messy installation can be the difference between “fine” and “why is it still weak?”
If you buy this, it helps to plan your run so the cable isn’t constantly under strain at the connector ends. SMA connections are straightforward, but they still need careful handling when you’re threading the lead around furniture and cable runs.
Also, since you get a pack of two, consider whether you’ll be extending more than one antenna lead (for example, twin-antenna router setups) or whether you want a spare for future repositioning.
Final verdict
It’s a solid pick if you need an SMA Male to SMA Female RG316 antenna extension for router/WiFi/WLAN-style setups and you want a flexible, low-loss 50 ohm coax link for relocating an external antenna.
You may want to skip it if you’re trying to solve a TV coax requirement (this isn’t for F-type TV use) or if your existing antenna/modem uses a different connector standard than SMA.
