[MRCA] coax recommendation sought

[Gene Smar]

Eugene:
 
     RG-8X will not handle legal limit power.  Check its specs.  Other than that issue, ordinary RG-type coax with a woven shield will work.  Hardline is not flexible enough to "meander" through the conduit so you're kind of stuck with ordinary coax.

     
     As for N vs -259s, the venerable -259 connector handles QRO better than the N.  N's provide a smoother impedance profile at UHF freqs but are problematic when you run power through them (I'm told by others on the TowerTalk reflector.)

   
     Finally, pull another pull tape through with the last coax run.  You'll have an easier time adding "just one more coax" to the run in the future.

Hello all,



I need to run some coax from the shack out about 160 feet to a vertical. Here?s the story. While having a new kitchen built this past fall and winter, I had the workers bury a flexible 2? conduit out to a new antenna site. It is a flexible conduit and I needed that because it had to meander a little to avoid bedrock and other outcroppings in the backyard. 



I am looking for some coax that is flexible so that it can be pulled through the conduit without too much trouble. I need legal limit HF and loss is not a huge issue for me considering its only 160 feet (total end-to-end) or so. Also there will be a coupler at the base so I am not worried about loss in the coax caused by SWR.



One last point, I need to make sure I can affix either a PL-259 or N connector, I haven?t decided yet. Can anyone make a recommendation? I?ve looked at bury-flex and RG-8X and some others but I am not sure what I should get.



Some other details: I will pull a mule tape through first, and I will grease the cable bundle as it goes through. I plan to run 2 coax and some multi conductor cable. Hopefully it will all fit within 2?;
