Radiodetection OmniMarker MK2 | RF Marker Ball for Electrical Power | Box of 30
The Radiodetection OmniMarker MK2 (Electrical Power) is a high-performance solution for marking critical underground utility points such as service entrances, transformer pads, and buried splice points. Encased in a high-visibility red housing, these markers allow for dual-layer safety by providing both a visual warning to excavators and a precise electronic signal for locating equipment. Operating at a frequency of 169.8 kHz, the MK2 ensures consistent detection in diverse soil conditions.
What frequency does the Electrical Power OmniMarker MK2 use?
This marker operates at the industry-standard frequency of 169.8 kHz, specifically reserved for electrical power utility identification. This precise frequency allows it to be detected by any electronic marker locator tuned to standard passive RF frequencies.
Why is the spherical signal pattern beneficial for utility marking?
The spherical signal pattern allows for faster and more accurate pinpointing compared to traditional dipoles because it creates a uniform field. Coupled with a self-leveling internal coil, the marker maintains an optimal vertical signal regardless of its orientation in the ground.
Do these RF markers require external power?
No, the OmniMarker MK2 uses passive technology that requires no batteries or external power sources. It is powered via induction from the locator’s electromagnetic field, ensuring a maintenance-free lifespan that often exceeds the life of the utility itself.
