Why Range Matters for Jetter Remotes
Sewer jetters are powerful machines used for clearing clogs and obstructions in sewer pipes by shooting a pressurized stream of water. Operating a sewer jetter requires expertise and knowledge to ensure its effective and safe use.
One of the key tools used for safe and effective use of a sewer jetter is the truck or trailer’s remote control. And one feature that really matters is the range of the remote.
Good range on a remote control for a sewer jetter allows the operator to control the machine from a distance, providing convenience, efficiency, and safety benefits.
Single operator efficiencies
With a remote that has sufficient range for a job, a single operator can control the sewer jetter, thus potentially reducing manpower costs and/or enabling work to continue when staffing is stretched. However, it is important to prioritize safety, and having a second operator posted at the unit is recommended to prevent other people from tampering with the unattended unit, which could lead to accidental injury.
Staying connected through obstructions
A good remote with reliable connectivity and range allows operators to control their sewer jetters without having to walk back to the machine. For many jobs it’s important to find a wireless remote system with transmit output power and receive sensitivity that can get signals through even the highest level of interference and structural materials – as may happen at hospitals, parking structures, and steel framed buildings.
Big jobs in big settings
Range is also important for sewer jetters used in larger settings. For instance, using remote control access for water jetters can make the process quicker and safer in larger residential and commercial settings. Additionally, range can be important for industrial-grade sewer jetters.
Make sure your remote has a range of well over 500 feet, as well as proven non-line of sight range. That's needed when snaking your hose up three flights of stairs and through concrete walls!
Evaluating a new remote for range – what to look for
Radio Spectrum: The frequency band and available spectrum for wireless communication play a significant role in determining the range of a remote control. Different frequencies can penetrate obstacles and interference to varying degrees, affecting the effective range.
When the job has direct line of sight range requirements, 900 MHz radios will transmit more than twice as far in free space as a 2.4 GHz radio when both radios use the same modulation and output power. A 900MHz radio system is also the best option for non-line of sight situations because it is at a lower frequency and will penetrate surfaces more easily. The range of frequency bands is important though in cases where there is interference from other nearby instrumentation that is operating on the same band and can cause interference. This is where frequency hopping becomes important for your transmitter to remain connected.
Signal Strength: The power of the transmitted signal from the remote control and the sensitivity of the receiver in the controlled device impact range. A stronger signal can cover a greater distance, but it can also be affected by interference and obstacles. The strength of a radio signal is measured in dBm and the higher that value, the stronger the signal.
Antenna Design: The design and quality of the antennas in both the remote control and the controlled device can significantly affect the range. High-gain antennas use a narrow radio beam that increases signal strength and can extend the coverage area.
Transmission Protocol: The communication protocol used by the remote control can impact range. Some protocols are better at handling interference and maintaining connections over longer distances. Look to see if your remote employs a frequency hopping spread spectrum (FHSS) which is a process used by many transceivers to make interception more difficult and reduce the impact of frequency-specific interference. This means your remote will be less likely to lose connection to the receiver.
Professionals who are trained in handling sewer jetters understand the appropriate water pressures, flow rates, and techniques required to clear clogs without causing damage to the pipes. To do this work safely and efficiently requires a reliable remote control - one that can stay connected to the truck no matter what the obstacles are in the way.
