Expert Advice: Do I Need a Signal Booster/Repeater for My Caravan TPMS?
I bet you're asking yourself, 'Do I need a signal booster/repeater for my caravan TPMS?' This is one of the most crucial questions we get from Australian caravanners. The answer determines whether your entire TPMS system works flawlessly or fails intermittently on the highway.
The short answer is: It depends entirely on your total rig length, but a good TPMS minimizes the necessity.
The Signal Reliability Test (Why Distance Matters)
A TPMS signal must travel from the sensor on the back axle of your caravan, through the caravan body (which can cause interference), and all the way to the display unit on your dashboard.
The Baseline: Most standard TPMS systems struggle with range once the total distance exceeds 12–14 metres. This is where signal dropout occurs, leaving your rear tyres—the most vulnerable—unmonitored.
Solution 1: Choose a System Built for Range (The Flatmate Aura)
The best way to avoid the need for a repeater is to start with a TPMS that has a proven, extended range.
The Flatmate Aura TPMS is engineered for this challenge, providing an unparalleled range of 25 metres (82 feet).
What This Means: For the vast majority of standard-to-large dual-axle caravans (up to 24ft/7.3m), the Aura’s 25m range is enough to guarantee continuous, reliable transmission from the rear axle to the tow vehicle without the hassle or extra cost of a booster.
Solution 2: When a Repeater Becomes Essential (Maximum Length)
A signal booster (or repeater) is necessary when your total rig length exceeds the TPMS's guaranteed range.
You ABSOLUTELY need a signal booster if:
Extreme Length: Your total rig length (tow vehicle + caravan) exceeds the 25-metre range of the Aura TPMS (e.g., for Extreme Max Length 41ft caravans).
Persistent Interference: You experience persistent signal dropouts due to heavy metal toolboxes or dense caravan construction interfering with the signal line of sight.
Expert Protocol: For the longest rigs (30ft+ or 41ft maximum length), we strongly recommend installing a booster to guarantee continuous, reliable transmission under all conditions, even with the Aura’s superior range.
Final Action: Measure Your Setup
To find the right system and avoid unnecessary purchases, measure your total rig length (front bumper to rear caravan axle).
Under 25m? The Flatmate Aura is your ideal, simple solution.
Over 25m? You need the Flatmate Aura PLUS a signal booster for guaranteed, end-to-end coverage.
