compared with other unlicensed and personal radio services
Compared with FRS (Family Radio Service) at 460 MHz:
MURS (at 150 MHz) permits four times more power (2 Watts TPO instead the 0.500 Watts ERP limit for FRS). At MURS frequencies, signals bend over hills better, but FRS signals are better at bouncing off of surfaces and penetrating into/escaping out of buildings. You may connect a MURS radio to an external or exterior antenna. FRS radios must employ a non-detachable antenna. For vehicle-to-vehicle operation with external (roof-mount) antennas, MURS should provide three to ten (or more) times the range possible with FRS radios. Compared with GMRS (General Mobile Radio Service) at 460 MHz: GMRS handheld radios have typically two to five watts transmitter power. GMRS vehicular units transmit typically with ten to 50 watts. There is no limit on the ERP of GMRS stations operating on the primary channels. GMRS stations may transmit with no more the 5 Watts ERP on the seven "interstitial" frequencies (those shared with the FRS). GMRS operation requires an FCC license. At MURS frequencies, signals bend over hills better, but GMRS signals are better at bouncing off of surfaces and penetrating into/escaping out of buildings. For vehicle-to-vehicle operation with external (roof-mount) antennas, MURS should provide one-and-a-half to four times the range possible with GMRS handheld radios also connected to roof-mount antennas. Depending on the surrounding terrain, MURS units connected to roof-mounted antennas might even outperform full-power (50 watt) GMRS mobile units, although the GMRS units should have a greater range in open terrain. Many GMRS radios can communicate through repeater stations for extended range (typically up to twenty miles or more, sometimes much more). The new FCC Rules will prohibit repeaters in MURS. |
