RF Datacom supplies industrial magnetic antenna mounting systems for water tanks, elevated steel structures, and telecom infrastructure — rated to 7,500+ lbs pull strength per mast with zero structural penetrations.
Welding and drilling into municipal water tanks voids warranties, introduces corrosion points, risks interior coating failure, and requires costly shutdowns. Epoxy fails with thermal cycling. There's a better way.
Zero structural penetrations — tank coatings and warranties remain fully intact.
Mounts install in hours with standard tools — no hot work permits, no shutdown required.
No bond failures from tank expansion and contraction. No paint grinding required.
Remove and reposition without any trace — ideal for temporary or evolving deployments.
All models use industrial-grade neodymium magnets in hot-dip galvanized steel housings. Available in Lite, Standard, and Heavy Duty configurations for tank tops, tank sides, rooftops, and wall structures.
Freestanding tripod-style mast mount for the flat or curved top of municipal water tanks and elevated steel structures. Three-leg design provides 360° stability with magnetic feet that conform to curved surfaces.
Magnetic mast bracket that attaches directly to the curved or flat steel side wall of a water tank, monopole, or building exterior. No through-bolts, no anchors, no surface damage.
Low-profile hinged magnetic base mount for flat membrane rooftops, parapet walls, and concrete decks over steel. Articulating hinge allows precise mast angle adjustment without roof penetration.
Maximum-strength configuration for large antenna arrays, microwave dishes, and multi-carrier equipment. 20–30 fixed neodymium magnets rated at ~250 lbs each for extreme wind-load and equipment-weight applications.
Have a non-standard structure, unusual curvature, or multi-antenna array requirement? RF Datacom works with Magnacurve's engineering team to specify the right mount configuration for your project — including custom magnet count, mast length, and bracket geometry.
No hot work permits. No structural engineering sign-off for penetrations. No tank shutdown. A two-person crew can complete a full tank-top or sidewall installation in a couple of hours.
Measure tank dimensions, confirm steel thickness, and select the correct mount model and magnet rating for your load and wind zone.
Place the magnetic base assembly at the desired location on the tank top or sidewall. No drilling, grinding, or surface prep required.
Confirm magnetic engagement, verify pull strength, adjust mast angle, and attach guy wires if required by load calculation.
Mount antennas, small cells, or microwave dishes to the mast. Run cables. System is operational — zero structural penetrations made.
From municipal water authorities to private tower owners, RF Datacom magnetic mounts serve any project where drilling is prohibited, impractical, or simply unnecessary.
From a single FMM-HD mast to a fully engineered 12-mast array — RF Datacom has the right configuration for every structure, load requirement, and antenna deployment.

RF Datacom is an authorized distributor of Magnacurve's patented FlexMag magnetic mounting systems — the industry's most rigorously engineered no-drill antenna mounts, built for the extreme demands of water tank and elevated structure deployments.
Individual FMM units can be linked together using cross-rail connectors, creating multi-mast array platforms for the heaviest telecom loads — all without a single weld, anchor, or structural penetration.
Individual FMM units bolt together via galvanized steel cross-rails, distributing load across the full array footprint. The platform is rigid, level, and repositionable as a unit — no anchors, no welding.
Four FMM-HD units linked with cross-rails. Ideal for large multi-carrier antenna arrays, microwave dish clusters, and heavy public safety deployments on water tank tops.
Eight FMM-HS units in a full octagonal cross-rail array. Supports the largest tower-top equipment packages — macro cell arrays, multi-band antenna clusters, and critical infrastructure deployments.
Pull strength ratings assume standard steel surface conditions. Actual pull strength can vary based on steel thickness, surface quality, and coating type. RF Datacom provides load calculations and site-specific configuration recommendations for all multi-mast deployments. Contact us for an engineered spec →
RF Datacom can perform custom structural engineering for all projects with Professional Engineers licensed in every state. Every multi-mast array deployment includes a full load analysis and stamped engineering package.
Stamped engineering drawings accepted by every AHJ, municipality, and water authority nationwide. No out-of-state registration delays.
Full load analysis for each site — wind speed, exposure category, and seismic zone — with member-by-member verification and magnetic hold-down calculations.
Every project receives a site-specific engineering package: structural drawings, load calculations, material certifications, and PE stamp ready for permit submission.
Full engineering drawings, magnet counts, pull strength ratings, and dimensional references for both the Tank Top (FMM) and Side Wall (FMM-W) product families — straight from Magnacurve.
Tripod-style freestanding mast system for flat or curved tank tops. Three sheets covering Lite (3,750 lbs), Standard (4,500 lbs), and Heavy Duty (7,500 lbs) configurations with full dimensional drawings and magnet specifications.
Magnetic bracket mast system for curved or flat tank side walls, monopoles, and building exteriors. Three sheets covering Lite (3,750 lbs), Standard (4,500 lbs), and Heavy Duty (7,500 lbs) with full mast length dimensions and detailed bracket views.
Tell us your structure type, antenna load, and location. We'll recommend the right mount, provide pull strength documentation, and get you a quote — usually within one business day.
RF Datacom has been supplying Magnacurve magnetic mounts since 2012 — with a 100% project success rate across every installation we have supported.
