If you’ve ever worked with RF (radio frequency) applications—think cell signal boosters, wireless routers, or IoT devices—you’ve probably encountered the N To TS9 Cable. As a supplier who’s spent years designing, testing, and shipping these cables, I’ve seen firsthand how critical understanding their connectors is for getting a seamless, reliable connection. A lot of my customers come to me confused: they know they need an N To TS9 Cable, but they’re not sure what connectors are actually inside, or why that matters for their setup. Today, I’m breaking down every connector you’ll find on this cable, how they work, and why choosing the right one can make or break your RF performance.
First, let’s start with the basics: what is an N To TS9 Cable, and why does it matter? This cable is a short-range RF jumper cable, designed to bridge two devices where one uses an N-type connector (most often on large, high-power equipment like signal boosters or antenna base stations) and the other uses a TS9 connector (common on small portable devices like 4G/5G modems, USB cellular dongles, or some compact Wi-Fi routers). The connectors at each end are not interchangeable—each is engineered for specific RF characteristics, so mixing them up can lead to signal loss, weak connectivity, or even equipment damage.


Let’s dive into the first, and most prominent, connector on one end: the N connector. Specifically, the N-type connector used in an N To TS9 Cable is almost always an N male connector. Let’s get into what makes it unique. The N connector is a coaxial RF connector, first developed in the 1940s by Paul Neill at Bell Labs, built for high-frequency applications (up to 11 GHz, and even higher for specialized versions). It’s an edge-to-edge design that’s threaded, which means it’s tightened with a wrench or connector nut to create a secure, weatherproof connection. For our cables, we exclusively use N male connectors—this means the center pin is a protruding metal post, and the outer conductor is a threaded barrel with male threads, meant to screw into a matching female N port.
Why N male? Because most of the devices that connect to TS9 cables (like signal boosters) have N female ports, so a male connector on the cable is the standard, most compatible fit. The N connector’s design minimizes signal loss, which is why it’s preferred for long-range or high-power applications. It’s also durable, able to withstand frequent connection and disconnection, and resistant to environmental factors like moisture when properly sealed. As a supplier, we only source N male connectors that meet industry standards for impedance (50 ohms, which is standard for most RF equipment) to ensure consistent performance. It’s worth noting that N connectors come in other configurations too—like N female, or even N Type To TNC Adapter for other use cases—but for our N To TS9 cables, N male is the go-to. If you’re working on a setup that requires a longer jumper between two N ports, we also offer options like the N Male To N Male RG213 Cable, built for higher frequency and lower signal loss than smaller RG cables.
Now, the other end of the N To TS9 Cable: the TS9 connector. This is the smaller, more compact connector, designed for devices where space is at a premium. Unlike the N connector, TS9 is a push-on (sometimes called “blade”) connector, not threaded. It’s a type of Mini coaxial connector, made for low-power, short-range RF connections, most commonly in cellular modems and portable Wi-Fi devices. The TS9 connector on our cables is also a male TS9 connector—meaning it has a small center pin and a spring-loaded outer shell that slides into a TS9 female port on your device, then locks into place with a small tab or friction.
What makes TS9 different from N? For starters, size: TS9 is tiny, about a third the diameter of an N connector, which is why it’s perfect for small dongles or compact routers. But that compactness comes with tradeoffs: TS9 connectors have a lower maximum frequency (usually around 6 GHz, vs. N’s 18 GHz) and are not as durable as N connectors, since their push-on design is more prone to wear if connected and disconnected frequently. That’s why our N To TS9 cables are designed for use cases where you’re connecting the TS9 end to a device that stays in place (or is only moved occasionally) and the N end to a fixed booster or antenna. We also make sure our TS9 connectors are impedance-matched (again, 50 ohms) to the N connector, so the entire cable doesn’t have a mismatch that causes signal reflection.
Wait, but what about the cable in between? Does that affect the connectors? Absolutely. The type of coaxial cable used in an N To TS9 Cable determines how the connectors are attached, and that impacts overall performance. Most of our N To TS9 cables use RG-174 or RG-316 cable—small, flexible coaxial cables that are perfect for tight spaces. But the cable’s construction (like the center conductor, dielectric, and outer shield) has to work with both the N and TS9 connectors to keep signal loss low. For example, a poorly attached TS9 connector to a thin RG-174 cable can cause the center pin to shift, leading to bad contact and signal loss. That’s why we assemble every cable in-house, testing each connector connection with a network analyzer before it ships—no pre-made, mass-assembled cables here.
Now, you might be wondering: are there different types of N To TS9 Cables with variations in connectors? Yes, depending on your needs. Some customers need reverse polarity versions, like RP-N male instead of standard N male. RP (reverse polarity) connectors swap the center pin and outer conductor: an RP-N male has a hollow center socket instead of a protruding pin, which is useful for devices where the standard N port is reversed. We offer RP-N options, but it’s important to note that TS9 connectors don’t come in reverse polarity—TS9’s standard polarity is universal for cellular modems, so mixing an RP-N with a standard TS9 can cause compatibility issues.
Another common question: can I adapt an N To TS9 Cable to work with other connectors? For example, if my modem uses a different connector instead of TS9, can I use a coupler? Sure. A lot of our customers use cables like the Waterproof RP-SMA Panel Mount Coupler to connect N To TS9 Cables to SMA-equipped devices, since SMA connectors are common in antennas and routers. Or, if you’re working with 5G equipment, some of our customers use the 4.3-10 Male To Nex10 Male Jumper Cable, but that’s for higher-power base stations—so always match your connector types to your devices, not just what sounds similar.
It’s also important to address common mistakes I see as a supplier. I’ve had customers come to me with a signal issue, only to find they bought a cheap N To TS9 Cable where the N connector was actually a fake, low-quality one. Fake N connectors often have incorrect threading, wrong impedance, or flimsy metal that bends easily. The center pin might be too short, so it doesn’t make full contact with the device’s N port, leading to significant signal loss. The same goes for TS9 connectors: cheap TS9s have flimsy outer shells that break, or center pins that wobble, which also causes bad connections. That’s why we only use military-grade materials for our connectors—copper-plated center pins, stainless steel threaded nuts for N connectors, and rugged ABS outer shells for TS9s. We test every connector pull: for N connectors, we check that they tighten evenly without cross-threading; for TS9s, we check that the lock tab clicks into place securely, so it doesn’t slip out during use.
Let’s also talk about impedance matching, because that’s where a lot of people go wrong. Both N and TS9 connectors are 50 ohms, which is the standard for all cellular and RF equipment. If a connector is 75 ohms (common in TV cables), using it in an N To TS9 Cable will cause a mismatch, leading to up to 50% signal loss. That’s why we never use 75-ohm connectors in our N To TS9 Cables—we test each connector’s impedance before assembly to make sure it matches the cable and the devices it’s connecting.
Another point: environment. If you’re using your N To TS9 Cable outdoors, you need connectors that are weatherproof. Our TS9 connectors come with rubber gaskets to seal out moisture, and our N connectors are gold-plated to resist corrosion (instead of tin-plated, which can rust in damp conditions). Gold plating also improves conductivity, so your signal stays strong. For outdoor setups, we recommend our shorter N To TS9 Cables, paired with a waterproof coupler if needed, to keep the connection sealed.
Wait, let’s circle back to the connectors themselves. Let’s make sure we’re clear on their physical structures, because that’s the most common source of confusion. The N male connector: when you look at it, you’ll see a threaded metal barrel (the outer conductor) with male threads, and in the center, a small, solid metal pin that protrudes about a quarter of an inch. To connect it, you screw it into a female N port, which has a matching threaded barrel and a hollow center socket. The TS9 male connector: it’s much smaller, about the size of a pencil eraser, with a spring-loaded outer ring and a tiny center pin. You push it into a TS9 female port on your modem or device, and the outer ring locks into place with a small tab so it doesn’t come loose accidentally.
I’ve found that a lot of first-time buyers mix up TS9 with other mini connectors, like SMA or UFL. UFL (also called IPEX) connectors are even smaller, used in tiny devices like Bluetooth modules, so they’re not the same as TS9. If you need a UFL connection, our team can also help you with adapters, like the FAKRA Plug To UFL IPEX1 Bulkhead Coaxial Cable Assembly Using RG178 Cable, for specialized setups—but that’s a different connector entirely, so don’t confuse it with TS9.
Now, why does this matter for you? Let’s use a real example: a customer who was using a cheap, off-brand N To TS9 Cable to connect a cellular modem to a signal booster in their remote cabin. They were getting only one bar of service, even with a high-gain antenna. When they switched to our cable, which has a tested N male connector and gold-plated TS9 connector, their signal jumped to four bars. The difference? The cheap cable’s N connector had a bent center pin that wasn’t making full contact, and the TS9 connector’s lock tab was weak, leading to intermittent disconnects. That’s why connector quality isn’t just a detail—it’s the difference between reliable connectivity and frustrating dead zones.
As a supplier, we also offer custom options. Some customers need longer N To TS9 Cables (up to 15 feet, though we recommend keeping it under 10 feet for minimal signal loss) for larger setups, or right-angle connectors to fit tight spaces. Our right-angle TS9 connectors are designed to bend at a 90-degree angle, so you don’t have to kink the cable around a modem or router, which can damage the inner shield over time. For our N connectors, we also offer flange mount options if you need to install the cable through a panel, though most of our customers prefer the standard threaded N male for bulk connections.
Let’s address a common myth: “All N connectors are the same.” No, not at all. There are differences in impedance (50 vs. 75 ohms), plating (gold vs. tin vs. nickel), thread pitch (standard vs. fine thread), and frequency rating. Our N male connectors are rated for up to 12 GHz, which is perfect for 5G and most cellular applications, while cheaper N connectors might only be rated for 2 GHz, leading to signal loss on higher frequency bands. That’s why we test every connector with a spectrum analyzer before assembly, to make sure it can handle the frequency of your device.
So, to wrap up, the two core connectors on an N To TS9 Cable are: 1) N male, a threaded, high-frequency connector for connecting to large RF devices like signal boosters or base stations, and 2) TS9 male, a compact push-on connector for small portable devices like cellular modems. Both are 50 ohm impedance-matched, assembled with durable materials, and tested for reliability. Choosing a cable with quality connectors isn’t just about fit—it’s about keeping your signal strong and consistent, especially as 5G networks become more widespread and devices demand higher performance.
