SIGNALPLUS Omni Directional Outdoor 4G 5G LTE GSM Cellular Antenna for Routers (698–6000 MHz, 10 dBi)
Quick take
This omni-directional outdoor cellular antenna is made to support wideband 4G/5G LTE and GSM frequencies (600–6000 MHz range listed) for use with routers and signal boosters. Buyers who can mount it outdoors (especially on rooftops or higher placements) report stronger in-house performance and more consistent reception than indoor antennas. The main caveat is compatibility: you need the right 50-ohm cable and connector setup for your booster or router.
Pros and cons
Pros
- Wide frequency support (listed 600–6000 MHz) for 4G/5G LTE and GSM-style networks.
- Omni-directional design intended for coverage without needing precise pointing.
- Includes mounting hardware and comes with a long RG58/50-3 cable plus adapters.
- N-female connector and 50-ohm impedance are clearly specified for matching common setups.
Cons
- Performance depends heavily on placement and line of sight, so results can vary by building and antenna height.
- Connector and cable compatibility can require extra adapters depending on your specific router or booster model.
What buyers think
Buyer-review evidence is limited to a small set of verified purchases, but the recurring themes are fairly clear. Several buyers describe an improvement in real-world reception after moving the antenna outside and running it to a router or booster. Users with challenging coverage environments, such as metal roofs or limited connectivity inside a structure, tend to mention better signal indoors after mounting the antenna higher. Setup is commonly described as straightforward, and the included mounting and cable/adapters help reduce friction.
What this antenna is for
This is an external cellular antenna intended to pair with a compatible 4G/5G LTE router or a cellular signal booster. It uses a wide frequency span, with specifications targeting 600–6000 MHz, and it’s designed as an omni-directional (vertically polarized) solution, so you typically do not need to aim it precisely like directional antennas.
Key specifications that matter for buying
Frequency range and gain
The antenna is specified for a wide band of 600–6000 MHz and lists a peak gain of 10 dBi (maximum). Wideband coverage can be useful when you want one antenna that can work across multiple LTE/GSM bands rather than swapping hardware for a specific carrier or region.
Impedance and connector
It uses a 50-ohm impedance and an N-female connector. That means your booster or modem side needs a compatible input, and you must plan for the correct cable and end connectors to avoid loss or mismatch. The listing also notes practical cabling requirements, including that a 50-ohm cable is needed and that connector types on the other end depend on your equipment.
Mounting and included accessories
In addition to the antenna, you get bracket and U-bolts hardware for exterior mounting. The package includes a 10-meter RG58/50-3 cable (with an N-male to SMA male reference cable in the listing bundle details) plus a TS-9 adapter and an N male adapter, which can help cover common booster input options.
Installation and performance reality check
For cellular antennas, placement often matters as much as the antenna model. The listing guidance emphasizes that results depend on the surrounding environment, antenna height, location, building clearance, and line of sight. In practical terms, buyers who see the biggest gains generally mount outdoors and place the antenna higher when possible, then route the cable cleanly to the router or booster.
Another important consideration is how your booster behaves. If your booster needs a minimum baseline signal level to operate effectively, an antenna upgrade may not fully solve weak-signal scenarios. One review described signal that went away at times when towers were present but the booster relied on being above a certain signal strength. This is less about the antenna being “bad” and more about end-to-end system requirements.
Pros and cons (expanded)
Pros
- Wideband support can simplify compatibility across bands for 4G/5G LTE and GSM-style networks.
- Omni-directional approach can reduce the need for careful aiming.
- Mounting hardware and cabling included help you get to a working outdoor setup faster.
- Clear interface specs (50-ohm, N-female) make it easier to plan a matching cable run.
Cons
- Compatibility is on you: connector matching may still require extra adapters if your router or booster uses a different coax standard.
- Environmental dependence: metal roofs, obstructions, and low mounting can limit improvement.
- System-level limitations: if your booster needs a strong incoming signal, results may not be stable in marginal areas.
Who should buy this antenna
- You want a wideband outdoor cellular antenna to use with a compatible 4G/5G LTE router or cellular signal booster.
- You prefer omni-directional coverage rather than a directional antenna that requires aiming.
- You have a use case where you can mount outdoors, like an RV, trailer, or home setup with limited indoor reception.
- You want the convenience of a bundle that includes mounting hardware and multiple adapters.
Who should avoid it
- If you are not sure your booster or router accepts an N-female interface (or you cannot configure the needed 50-ohm cable and adapters), you may end up with extra hardware needs.
- If your location is extremely weak and your booster requires a strong baseline, you may see limited improvement.
- If you are expecting a “set it anywhere” outcome, remember that antenna height and line of sight are key, placement can make or break results.
Verdict
The SIGNALPLUS omni-directional outdoor antenna is a solid fit for shoppers who want wideband support and a more practical outdoor setup for routers and boosters. Buyers typically report better in-house reception after mounting outdoors, but success depends on getting the signal path right, including proper cable matching and realistic placement. If your biggest challenge is finding the right connector setup, verify your booster or router input requirements before purchase, and plan to mount it where it can “see” the tower.

FAQ
Is this antenna compatible with Verizon, AT&T, T-Mobile, and other US carriers?
The antenna is designed for wide coverage across 4G/5G LTE and GSM-style networks within the listed 600–6000 MHz range. Carrier compatibility still depends on whether your specific router or booster supports those bands and how the system routes the antenna connection.
What cable and connector do I need?
It is a 50-ohm antenna with an N-female connector. You need a matching 50-ohm coax cable and connectors that match your booster or router input. The bundle includes cable and adapters intended to cover common setups, but additional adapters may be needed for certain equipment.
Does it need power?
No, it is described as plug-and-play and does not require power. You connect it to your router or booster using the proper cable and adapters.
Is this antenna directional or omni-directional?
It is omni-directional, meaning you typically do not need to aim it at a specific tower direction. Placement and height still matter because obstacles can reduce reception.
Will a stronger antenna fix weak signal in all locations?
Not always. If your cellular booster requires a minimum incoming signal level to perform well, very weak or unstable coverage may still limit results. In those cases, you may need to improve placement, reduce obstructions, or consider a different approach for boosting.
Can I replace an older antenna with different connectors?
Sometimes, but you must match the coax connector standard. The included adapters may help, but verify your existing cabling and connector type first.
