Extruded Radome Plastic Profile - Engineered for Base-Station RF Performance
A radome plastic profile - also called an antenna radome, radome cover or RF-transparent antenna enclosure - is the weatherproof shell that lets a base-station antenna keep transmitting while wind, UV and water stay outside. This big-section profile is extruded as one continuous cover, not molded in segments, so a single length spans a full sector or panel antenna with no field-assembled seams to scatter signal, distort the beam or admit moisture.
Wall geometry and dielectric constant are tuned for low insertion loss and clean return loss across the 0.9–5 GHz sub-6 band, holding VSWR under 1.5 on directional receiving antennas - so signal integrity through the radome wall tracks a bare antenna. Run in UV-grade ASA, ABS and UPVC, this radio-frequency-transparent cover carries the RF window a 4G/LTE or 5G NR array needs without the dead weight that complicates tower-top work.
Because the cross-section is constant, one extrusion die serves every cut length - arrays that change size from site to site reuse the same tooling, removing the per-size mold cost that scales badly on large molded radomes. It is the difference between buying a continuous antenna housing and managing a catalog of molded shells.
Large-Section Antenna Radome Cover - Key Buyer Advantages
Three reasons the large-section extruded radome profile changes the procurement math on a multi-site rollout.
Signal stays in the link budget
Wall thickness and dielectric constant are matched to the band, so insertion loss and return loss across the 0.9–5 GHz sub-6 range stay minimal and VSWR holds below 1.5 on directional receiving antennas - signal integrity through the cover tracks the bare antenna.
For buyers: the enclosure adds no measurable margin loss - the RF plan done for a bare antenna still holds once it is covered, so you are not re-tuning cells after install.
One shell, not a bolted assembly
The continuous large-section profile is engineered for wind load, seismic movement, ingress protection and lightning-protection layout, with mounting designed around tower-top service access.
For buyers: fewer joints means fewer failure points and fewer water-ingress paths over a 10-year tower life - and a crew swaps one length faster than it rebuilds a multi-piece housing at height.
Rated for outdoor base-station duty
UV-grade, anti-aging ASA / ABS / UPVC resists embrittlement and chalking through repeated thermal cycling, with high impact strength plus chemical, salt-spray and corrosion resistance held across the full heat-and-cold range.
For buyers: on coastal and high-UV towers, the cover that fails first on cheaper material is simply not your replacement line item - color and structure hold across the antenna's service life.
UV-Grade Radome Plastic Profile - Material & Extrusion
Material choice sets the radome's signal loss, weatherability and cost, so we extrude to the band and the environment rather than a single default. As weatherable thermoplastics, UV-stabilized ASA (acrylonitrile styrene acrylate), ABS and UPVC each trade UV life, impact strength and price differently - and profile extrusion runs single, co- or tri-layer, letting a hard weatherable skin sit over a structural core in one pass.
A constant cross-section is what makes the large format affordable: sections up to 500 mm come off the line at any length without new tooling, so the per-size die cost that drives big molded radomes disappears. Where strength-to-weight leads on the largest structural spans, glass-fiber-reinforced PC or PP is available alongside the standard resin set, with the dielectric kept low-loss across the band.
| ASA · UV | Highest UV & color retention. First choice for high-exposure, desert and equatorial tower sites. |
| UPVC | Lowest cost per meter. Built for high-volume 2G / 3G / 5G base-station programs. |
| UV-ABS | Impact strength for handling. Suits deployments where covers see rough transit and field fitting. |
| PC / PP-GF | Strength-to-weight for large sections. Glass-reinforced option for the biggest structural spans. |
Antenna Radome Cover Applications - Telecom, 5G & Infrastructure
Base-station antenna enclosures
Continuous covers for sector, panel and MIMO antennas on macro cells and small cells - one extruded length per face instead of a stack of molded shells.
Meteorological & radar covers
Weatherproof, RF-transparent housings for ground weather-radar and meteorology antennas under long-term outdoor and coastal exposure.
Macro & 5G tower arrays
Large-section profiles sized to multi-band, broadband 5G NR sub-6 arrays for mobile network operators, where a consistent RF window across the whole array matters most.
Aerospace & ground stations
Antenna shells for satcom ground-station and aerospace links where signal integrity and weather sealing are both mission-critical.
Across all of these the same large-section extruded radome plastic profile does the job - a continuous, RF-transparent antenna cover sized to the array rather than a catalog of molded shells. The constant section suits point-to-point microwave backhaul links and outdoor Wi-Fi / WLAN access points in the 2.4 and 5 GHz bands just as readily as a cellular base station.
Custom Big Radome Plastic Profile - OEM Manufacturing for Project Buyers
Send the antenna's dimensions, band and gain target - or just the antenna itself - and we tool to it. Custom radome extrusion from your samples or drawings is standard work here, not a special order, whether you need a private-label OEM antenna cover or an ODM design developed from scratch.
In-house tooling means a new cross-section is cut on our own line rather than subcontracted, so a first sample moves on the timeframe a project schedule needs. Eleven base resins are held in stock for single, co- and tri-extrusion, and secondary work is done before the profile ships - so what arrives on site bolts up without a second vendor.
| SECTION | Custom cross-section & length, to 500 mm section |
| MATERIAL | ASA · ABS · UPVC · PC · PMMA · PP · PE · PS · POM · PA · PET |
| STRUCTURE | Single / co / tri-layer - weatherable skin over structural core |
| COLOR | Gray, white or matched to spec |
| RF TUNING | Wall geometry set to your band & gain target |
| FINISHING | Drilling · punching · angle cutting · cut-to-length · assembly |
Compliance & Quality Assurance for Every RF Cover
Every length is checked where it matters for an RF cover: insertion loss and VSWR are verified against the target band, UV-grade resins are confirmed for weatherability, and dimensional tolerance is held so the cover seats on the antenna without shimming.
Export orders are supported with the compliance documentation telecom procurement asks for - so the cover clears the same gates as the rest of the bill of materials.

Big Radome Plastic Profile - Procurement FAQs
Q: What is the largest radome section you can extrude?
A: Sections up to 500 mm come off our lines as a single continuous profile, at any cut length. For an array longer than one extrusion run, lengths are matched so the RF window stays consistent across the join.
Q: Will the cover add signal loss to my base-station antenna?
A: A correctly specified antenna radome keeps insertion loss and return loss minimal and VSWR under 1.5 on directional receiving antennas. Dachang, as a radome plastic profile manufacturer, matches wall geometry and dielectric to your band - 0.9 to 5 GHz - so the enclosure stays inside the link budget planned for the bare antenna.
Q: What's the difference between an extruded radome profile and a molded radome?
A: An extruded radome plastic profile has a constant cross-section, so one die produces any cut length without new tooling, and a single continuous cover spans a full sector or panel antenna with fewer seams. A molded radome needs a dedicated mold per size - which raises per-size cost and adds joints on large covers. For big base-station and array enclosures, extrusion is usually the lower-cost, lower-risk route.
Q: Which material should I specify for my site?
A: UV-grade ASA for the longest UV and color hold on high-exposure towers; UPVC for cost-driven high-volume builds; UV-ABS or glass-filled PC/PP where impact strength and strength-to-weight lead. Send the environment and band and we will recommend the resin and layer structure.
Q: Can you make a custom shape from our antenna?
A: Yes - custom U, square, W or bespoke cross-sections are tooled from your samples or drawings. Dachang, as a radome plastic profile supplier with an in-house tooling shop, cuts the die on our own line, so a first sample is not gated behind a subcontractor.
Q: Do you supply radome covers for 5G base stations and Wi-Fi access points?
A: Yes. The 0.9–5 GHz range covers 4G/LTE and 5G NR sub-6 base-station antennas, point-to-point microwave backhaul, and outdoor Wi-Fi / WLAN access points in the 2.4 and 5 GHz bands. Wall geometry and resin are tuned to the band you specify, so the same large-section profile serves cellular and wireless-infrastructure programs alike.
Q: What certifications ship with the order?
A: Export orders are supported with CE, RoHS, SGS and ISO 9001 documentation for telecom procurement. Insertion loss, VSWR and UV-weatherability are verified before shipment so the cover qualifies on both RF and durability.
Q: Are you a manufacturer or a trading company, and do you export?
A: Dachang is a China-based radome plastic profile factory extruding antenna covers in-house since 1998, with our own tooling shop. We export worldwide and ship factory-direct, so pricing, lead time and engineering answers come from the line that makes the part rather than a middleman.
Q: How is a radome plastic profile priced, and what are MOQ and lead time?
A: Pricing is per meter by cross-section and material, with the custom die amortized over a project run rather than one piece - so unit cost drops as volume rises. Sample and pilot quantities are accepted to qualify a profile; volume MOQ is set per die and material. Container lead time is around 30 days after a confirmed order, and faster on repeat cuts from an existing die.
