DAS Service, Repair & Upgrades
Buildings change. Tenants build out, carriers refarm spectrum, amplifiers age out, and a system that covered the floor plan five years ago now leaves whole zones dark.
Diagnostic visit
1–2 days on site
Reuse potential
Existing coax where loss allows
Response
Priority dispatch under contract
Monitoring
Remote alarming available
Straight answers
What it is, what it costs, whether you need it.
Coverage that used to work has degraded, or a build-out changed the building after the system was designed.
No gated pricing, no “contact us for a quote” on the basics. Every number below is the range we actually quote in commercial buildings; your survey replaces it with a fixed figure.
What does service and upgrade work cover?
Diagnosing an underperforming or dead system: donor alignment, amplifier faults, oscillation, water-damaged connectors, failed splitters, and coverage lost to new walls or tenant build-outs. We repair, re-balance, or extend the existing system rather than sell a replacement by default.
What does it cost?
Diagnostic visits are a flat fee per building; repairs and zone extensions are quoted against findings. Full replacement is only recommended when the existing head-end is obsolete or out of FCC certification.
Can you service a system you didn't install?
Yes — a large share of this work is inherited systems, including ones whose original installer is out of business.
This is the right scope if
- Coverage degraded after a tenant build-out or addition
- Amplifier alarms, shutdowns or oscillation
- The original installer is unreachable
- You're taking over a building with unknown equipment
We’ll point you elsewhere if
- No system exists — see passive DAS installation
What this covers
How the scope actually runs.
We start with a diagnostic benchmark against the current floor plan, then identify the actual cause — donor drift, oscillation shutdown, water intrusion at the roof penetration, failed splitters, or simply a system that was undersized on day one.
From there the fix is either repair, re-balance, zone expansion, or a head-end swap to modern 5-band certified hardware that reuses the existing coax plant wherever the loss budget allows. Reusing usable infrastructure is typically 40–60% cheaper than a full rip and replace.
Service agreements include remote monitoring, priority dispatch and scheduled preventive checks so the next failure is caught before your staff report it.
Deliverables

How we deliver it
Four stages, documented at every hand-off.
01
Fault diagnosis
Head-end alarm review, isolation testing and branch-level signal tracing.

Repair plan
Repair, re-balance or replace — with the cost of each option stated up front.
03
Execution
Component swap, cable repair, antenna re-siting or amplifier upgrade.
04
Re-certification
Full re-commission and updated heat maps so the building file stays current.

Answers
Asked about this service
Our booster keeps shutting itself off. Why?+
Almost always oscillation — the donor and interior antennas are hearing each other — or an uplink overload protection trip. Both are diagnosable on the first visit.
Can you expand a system we did not install?+
Yes, provided the existing head-end has headroom and the coax plant tests within the loss budget. The diagnostic visit determines that.
