Find it, locate it, fix what's fixable.

Five defined ways to engage one independent RF engineer. Each starts with the buyer's problem and states the practical output, timing and next step.

Five purchasable RF services.

If you are unsure, send the symptoms and location. The initial review will identify the most appropriate route before any work is agreed.

RF Interference Investigation

Something is breaking your wireless and you need it found — now.

When a network, control system, sensor array or radio link starts failing and nobody can explain it, the cause is usually an RF source nobody's looking for. I survey the affected area, characterise what's actually on the air, and separate signal from noise to pin down the disruption.

Scope
  • Unknown / unidentified signals
  • Wireless system disruption
  • Intermittent communication failures
  • Co-site & co-channel interference
  • Spectrum occupancy analysis
02
Signal hunting

RF Source Location

There's a transmitter that shouldn't be there. I pinpoint it.

Finding a source that doesn't want to be found is its own discipline. Using direction finding and signal-hunting technique honed in counter-surveillance work, I track interference back to its origin — whether that's a failing supply two units away or an external emitter bleeding into your band.

Scope
  • Transmitter identification & location
  • Direction finding
  • Signal hunting
  • Interference source identification
  • On-site interference surveys
03
Performance

Wireless Systems Diagnostics

Your links, range or telemetry aren't performing as they should.

Not every RF problem is dramatic interference — sometimes a link just underperforms. I investigate poor range, unreliable links and flaky telemetry from the antenna and receiver up, finding the physical-layer reason the system isn't doing what the datasheet promised.

Scope
  • Poor radio range
  • Link reliability & dropouts
  • Telemetry problems
  • Antenna system investigations
  • Receiver sensitivity / desense
04
Resolution

RF Remediation

Once it's found, I engineer the fix — on my own bench.

This is the part most consultants skip. With a real workshop behind the practice, the remedy gets built and fitted, not subcontracted. Shielding, filtering, bonding and antenna re-work designed and fabricated to resolve the specific problem — diagnosis and cure under one roof.

Scope
  • Shielding design & fabrication
  • Filtering & ferrite / bonding solutions
  • Antenna re-engineering
  • Enclosure modifications
  • Bench-built custom remedies
05
Independent

Independent RF Technical Investigation

You need a neutral, vendor-free technical verdict.

When a claim needs verifying or a dispute needs an impartial read, independence is the whole value. Selling no hardware and tied to no installer, I provide third-party assessment, failure analysis and performance verification that stands up because it has no other agenda.

Scope
  • Third-party technical assessment
  • Failure analysis
  • Root-cause investigation
  • Performance verification
  • Installer / vendor claim verification
  • Dispute & expert support
How engagements work

Three ways to work together.

Priority callout

Fixed-fee response visit when something's failing now. Located, proven, and a clear plan for the remedy before I leave.

Planned survey

Booked RF or wireless survey — baseline your environment or catch problems before they bite.

Resilience retainer

Guaranteed response time and priority callout for sites that can't afford the downtime, with your RF baseline on file.

Specialist & consultancy services

Beyond the callout.

For operators

Asset Tracking Diagnostics →

Why is your GPS tracking unreliable? Independent diagnosis of reception, cellular backhaul, coverage gaps, antenna faults and jamming — for fleet, plant, logistics and lone-worker.

For infrastructure

GNSS Vulnerability Assessment →

An independent on-site survey of your exposure to GNSS jamming and spoofing — risk-rated report and mitigation plan. For ports, rail, logistics, data centres and utilities.

For legal teams

RF & Electronics Expert Witness →

Independent expert opinion in RF, GNSS, surveillance, counter-drone and electronics disputes. CPR Part 35 compliant; instructed by either side.

RF / EMF exposure measurement

EMF Survey & Testing Services
