RF & Wireless Education
​RF is invisible, unforgiving, and indifferent to your schedule. Wireless audio works when the environment is understood, anticipated, and respected. The goal is reliability through preparation, not reaction.

Goal
Stable wireless audio with minimal dropouts or surprises.​
​

​

Method
Understand the RF environment, coordinate frequencies intentionally, and monitor continuously.

Result
Fewer hits, calmer days, and confidence when conditions change.
​

Location Dependent

Coordination First

Monitor Everything

RF in One Sentence
RF problems are solved before they happen, not after they show up in the take.​

What Affects RF Performance

Physical distance between transmitter and receiver
Obstructions like bodies, walls, vehicles, and metal
Competing RF sources in the environment
Antenna placement and orientation
Transmitter power and battery health

​
​Most RF issues are environmental, not equipment failures

Frequency Coordination Fundamentals

Start with a Scan	Always scan the environment before assigning frequencies. Never assume yesterday’s coordination still applies
Avoid Crowded Ranges	Stay clear of known problem bands when possible. Do not force coordination into hostile spectrum.​
Leave spacing	Give channels just enough separation to coexist cleanly. Crowding invites intermodulation.

Antenna Placement Principles

Height Helps	Higher placement usually improves line of sight and stability.
Distance Matters	Closer to your transmitters is better. Avoid unnecessary cable runs and losses.
Orientation Counts	Maintain consistent antenna polarization when possible.​

RF is a system, not a setting

Treat it like one.

Transmitters

Verify power settings match the environment
Monitor battery voltage, not just battery percentage
Secure transmitters to prevent movement related dropouts

A perfectly coordinated system fails if the transmitter is neglected.

Receivers

Confirm correct frequency assignment

Watch RF and audio meters, not just one or the other
​
Identify marginal channels early

RF meters tell you about stability. Audio meters tell you about success.

Common RF Mistakes

Coordinating too quickly without scanning

Ignoring antenna placement

Running transmitters at maximum power unnecessarily

Waiting for problems instead of anticipating them
