Your Price: $908.00
This heavy duty outdoor unit can be used with all of our MURS devices and radios for long range outdoor wireless communication.
Part Number: RT1027
Running wires over long distances or over areas that are concrete or asphalt can cost thousands of dollars and may require time-delaying digging permits. And then the wiring eventually goes bad or is accidentally cut and you have to do it all over again. A cheaper and faster solution is to install a MURS Callbox.


Wireless Callbox BrochureThe MURS XT Callbox works with our other MURS radios and it provides long range, 2-way voice communication from the fixed location of the Callbox to any of your other MURS intercom units. It has a range of up to one mile or more with an optional external antenna.

See the applications and other products available for MURS in the MURS Product Brochure (requires the free Adobe PDF Reader to view and print).

This heavy duty outdoor intercom is designed for construction sites, golf courses, hotels/motels, airport parking lots, gated entrances, manufacturing, college campuses, hospitals, receiving docks, amusement parks, resorts, locked entrances, farms, ranches, warehouses, campgrounds, parking lots, delivery doors, and any other application that needs two way communication for safety or convenience.

There is no need for extensive wiring, trenching, remodeling, or installing dedicated phone lines with expensive monthly fees since the MURS Callbox is completely wireless.


For simple installation, the MURS Callbox is designed to operate on 6 D-cell batteries (alkaline or Ni-Cad rechargeable). An optional external power supply is also available.

The MURS Callbox has two modes of power consumption. In Automatic Turn-Off the unit turns itself off after a programmed amount of inactivity (up to 4 minutes). It can only be turned on again by pressing its Call button on the Callbox. In this mode it cannot receive calls from other intercom or handheld radio units. It can only make calls and then other units can respond.

In Normal mode, the unit does not turn itself off and the MURS Callbox can not only make calls, but receive them as well. This mode consumes the largest amount of power and should only be considered if an external source of power is available. If an external source of power is used, the internal batteries can be installed as a back-up against loss of

The MURS Callbox is housed in a fiberglass enclosure with a stainless steel faceplate that includes tamper-resistant fasteners and a concealed antenna making it perfect to withstand harsh elements.

Since this callbox operates in the MURS frequencies, no FCC license is required.

"We are using your Callbox XT at our RV park as an answering device for our arriving residents to get in touch with the persons on duty. They call us at our homes, we go down to the office to answer questions or to check them in. The callbox allows us the flexibility of using the device in 3 areas at a time - our old system was hard wired to one place only. We all love the flexibility and range of your unit."

Cynthia Crisp,Friendly Acres RV Park, Yuma, AZ

"We ordered two call boxes for use at a large manufacturing plant. One callbox with a keypad allows people to use an access code to enter the gated parking lot, or they can call in and the gate can be opened remotely. The other callbox is used for visitors to announce themselves for entry into the office area. The wireless aspect of these callboxes is the main reason they work since installing boxes that needed to be wired was not possible."

Don Yeackley, Bottom Line Solutions, Milford, NE

"We purchased the MURS 4 Mile Range and MURS Commercial Intercoms because one of our Preschool classrooms is far removed from the office - there was no way of communicating electronically/ rapidly which is of special concern in case of emergency. We decided to purchase the outdoor Callbox XT to put out on our playground.

The classroom piece of the intercom has saved much frustration and time simply by eliminating the need for a staff member to either leave her classroom to walk to the office or vice versa. Our office staff (one of whom is handicapped) LOVES them because they don't have to get up and down repeatedly to deliver messages/ gather information, etcetera. It's all done through the new intercoms. They provide peace of mind in case there is an emergency."

Stephanie Molina, Southwest Child Care and Education Centers, Albuquerque, NM

"We have a side entrance to my building which is locked for security, but this entry serves as handicapped access as the front entry has a step. Because the building is historic and cannot be altered, the Massachusetts Access Board granted a waiver to allow this set-up as long as there was an intercom available at the locked entry so that handicapped persons could call in to the office and have someone come and unlock the door to grant them access to the building.


Your callbox is weather resistant and battery operated which allowed for easy installation in this location. The cost was more competitive than phone system intercoms."
