I installed a 2.4 g radio system, I'm having trouble. I ran 100 ft of RG 58 in a EMT / Ridged pipe with a mast on top. Can EMT or ridged pipe for thirty feet effect the radio waves and transmit careerists of the radio? Rich The problem is most likely with the 100 feet of RG58. At 2.4GHz there'll be so much loss that no signal will get to the antenna. You need to replace it with extremely low-loss coax or hard-line. |

That means 1/1000th of your received signal makes it to the radio and 1/1000th of the transmit signal actually gets radiated. Sure fire formula for failure. Go get some LMR-400 or LMR-600 cable and connectors. Dale W4OP |

hi, your RG58 is not a wonderful coax for those frequencies.
In fact, you should use hard line. Way too much loss with any kind or regular coax. good luck, Mark Rich wrote: I installed a 2.4 g radio system, I'm having trouble.

That was factory supplied with there ends, The 100 ft has to be in tact to
regulate the power out. "Richard Cranium" wrote in message om... Rich wrote in message ... I installed a 2.4 g radio system, I'm having trouble.

I have to look what they type of cable they supply.
out of 15 we only had trouble in the ones in pipe. all of the others are surface wiring. "Dale Parfitt" wrote in message ... Rich wrote: I installed a 2.4 g radio system, I'm having trouble.

I am sorry 450 mhz to the top and then converts to 2.4 G
It sends power up to the top. My question is Running the RG-58 up the inside of the pipe for thirty ft. Dose that cause interfearence. |

Requires the 100 Ft in tact. To limit the amount of power to the converter at the top. This is two out of 15 that we set up and the only in metal conduit. The receivers will not latch or associate with the host. Monday we will call the rep. I was just pulling straws, making a good responses to the boss on Monday morning. I know when I specked a building I all ways ask for PVC to the roof. "Dave Holford" wrote in message ...

Dose that cause interfearence. I don't know about the pipe, unless you have RF on the outside of the co-ax, but 100 feet of RG-58 should certainly 'regulate' the power; even at 450MHz. I'd be inclined to replace 'regulate' with 'reduce'. Dave |
