"jimbo" wrote in message oups.com... Conduit sounds like a good idea. Would you use metal or PVC? jimbo Well, it depends on a lot of factors. You have to use lubricant to pull long runs of PVC insulated coax through PVC conduit, while metal is slicker, and sometimes it will pull without. Metal will provide little additional shielding, and bending big stuff requires special benders, while PVC can be formed with a heat gun and a lot of care. For individual runs, you could use this corrugated PVC stuff which has become very popular for pulling fiber optics, but I have never seen it in real large sizes, and it will need to be held down more if it has a lot of turns. -- Crazy George Remove N O and S P A M imbedded in return address |

I am building a new house. I need two coax runs inside the house for two uses. First, for 2 meter, 440 MHz dual band. Second for 2-30 MHz HF. I am considering using RG213/U for both runs. I know this coax is suitable for 440 MHz on runs less than 100 feet. Would there be any problems for the 2 meter or HF using this coax? Or are there any suggestions for this project? Thanks, jimbo I did the same thing when I put in the ham shack but I ran 8 runs of LMR400 cable and also two runs of 8 conductor cable for rotor's. The outside panel is under the eve of the house and I have another panel on the wall of the shack. Tye LMR 400 Ultra Flex is what I used. |

How many of the eight runs do you use at one time? And I guess the
other runs are spares? Did you consider conduit, so you could replace cables if required rather than spare runs? Thanks, jimbo Bill wrote: jimbo wrote: I am building a new house.

I have seven antennas up right now so there is only one spare run and one spare run for a rotator. I would guess conduit would be ok but for what I have it's not needed. I can replace a run here by soldering the center and outer shield to the new piece and pull it through with out any problems, if the cables had been run other than the way they are now then conduit would have made things easier. |

I'd run lower loss coax for the UHF/VHF than RG-213/U, e.g. LMR400, Belden
9913F, etc, unless the run was less than 25 feet or so, maybe 50ft. For HF thru 10m (or even 6m) though the RG-213 should be just fine. It may be cheaper though to just buy a spool of the low loss and use it for the HF too than to buy two types of coax. Like the conduit/EMT idea (make'm BIG and run a couple). Also, now's the time to run a *dedicated* circuit to the shack for a 240V amp supply. if not needed, it could be connected to 120V instead and the receptacle changed, but power only a single outlet box w/ it so you can easily switch to 240 V (duplex vs single breaker and new recepticle).
