Our fixed frequency analog VHF transmitters are designed for use up to 70 feet.
For customers with larger RVs, trailers, or 5th wheels, we recommend upgrading to our adjustable frequency digital UHF transmitters. They feature a pairing button that allows you to change the frequency they operate on.
For customers who need the ultimate in reliability and range, our ultimate hulk transmitters are rated at 1000 feet of range. They feature heavy duty construction and automatically adjust frequency if any interference is detected. They are designed for construction equipment, and are great for large metal trailers that can interfere with other wireless systems.
