Can I make some attenna to connect to a murs or FRS radio from the station at the bottom of the hill(because it will be staionary). So if the radio w/o the super attenna only has a short range but the stationary radio will send and receive all the signals from the normal one correct? If theirs a normal radio at one end then another somewhere else could the super attenna from the stationary extend their range? |

[snip] Other than truckers, and the odd amatuer radio buff trying to skip CB signal around the globe, you should find the CB Band pretty clear these days! Also, there are many companies who sell CB radio amplifiers (AKA Linears) that will increase the transmit power of the units. These devises will be illegal if they boost the transmit power over of what is allowed by the FCC (5 watts) but they are out there, and available if people want to use them. [snip] |

EXCUSE ME? I think you would have to look long and hard to find an amateur messing around in non amateur bands. Hams are exceptionally noted for doing an excellent job self policing themselves. Not to mention that there would be no reason for a ham to use those frequencies, as they wouldn't find anyone there that they could talk to, except for other hams breaking the law as well. And as far as I am informed, there are no legal linear amplifiers for use on the citizens band radio. Most that you will find are home made, and also tend to be of rather poor design, and produce large amounts of spurious emissions. Not to start a flame war, but I just feel the need to defend often misunderstood amateur operators. -Mikey P (KC8JHS) |

If theirs a normal radio at one end then another somewhere else could the super attenna from the stationary extend their range? Unfortunately, FRS/GMRS radios (at least all the handheld ones that I have seen) all seem to use built in antennas with no provision for using an external one. There may be GRMS radios out there that have external antenna capabilities, I just have not seen them. |

To look at them you wouldn't realize they are removable. They use what's called an SMA connector. |

SMA connectors are commonly used for microwave applications. They do a gas-tight seal and have excellent signal-transfer characteristics. Somewhere in a tool box, I have the proper torque wrench one should use when tightening these connectors. -a |

Better units offer all 14 channels, and even privacy codes so you don't hear or interfere with others using the same channel. |
