airMAX 5 GHz, 30 dBi RocketDish LW (RD-5G30-LW) is a specialized dish antenna from Ubiquiti, designed to pair with a Rocket-series radio for point-to-point links in genuinely challenging RF environments. The “LW” designation reflects its extended-depth dish reflector, purpose-built to reject noise interference in co-location deployments where multiple radios operate in close proximity.
The airMAX 5 GHz RocketDish LW delivers 30 dBi gain across its 5.1–5.9 GHz frequency range, with a 5.8° beamwidth on both horizontal and vertical polarization. What sets this variant apart from Ubiquiti’s standard RocketDish is its extended-depth reflector design — a physical modification that meaningfully improves front-to-back rejection and reduces the antenna’s susceptibility to interference from nearby co-located radios operating on adjacent towers or shared mounting structures.
This makes the airMAX 5 GHz RocketDish LW a genuinely valuable choice for tower sites where multiple point-to-point or point-to-multipoint links are deployed close together, a common scenario for WISPs managing dense network infrastructure across shared mounting locations. Reducing inter-radio interference in these environments translates directly into more stable, predictable link performance.
RF specifications include an F/B ratio of 30 dB and a max VSWR of 1.6:1, with dual-linear polarization and a minimum cross-pol isolation of 35 dB — solid, dependable figures for demanding backhaul applications. Like other RocketDish models, this is an antenna-only product, requiring a separately purchased Rocket-series radio to complete a working link.
Physically, the airMAX 5 GHz RocketDish LW measures 650 x 650 x 386mm and weighs 7.4kg — notably lighter than the standard RD-5G30 despite its extended-depth design, thanks to construction optimizations. It’s rated for wind loading up to 790N at 200km/h (125mph), with matching wind survivability at that same rating, and includes a universal pole mount, Rocket bracket, and weatherproof RF connectors in the box.
The unit complies with ETSI EN 302 326 DN2 specification and is confirmed NDAA compliant, giving installers confidence for deployments with regulatory or government procurement requirements around supply chain compliance.
For WISPs and integrators managing tower sites with multiple co-located radios, the airMAX 5 GHz RocketDish LW offers a genuinely purpose-built solution for reducing interference and maintaining reliable link performance in crowded RF environments where a standard dish antenna might struggle.
