Crackerjack,
Solid Core Coax
+ Good for long runs or use with No tight bends.
- Not good for connecting to beams or making tight bends to equipment.
Stranded Coax
+ Good for Connecting to Beams and general use where you need the flexabilty and good for Jumpers.
- None that I have found.

Thanks... Lon.
That is what I like, nice and complete -and easy to digest.

Stranded coax would seem to be better due to the 'skin effect'. Also, the capacitance should be lower because of the multiple strands. |

I would use stranded core coax simply because of the physical stresses that vibration and flexing have on the wire. If you take a solid piece of wire and flex it numerous times, at some point it will break, take the same guage in a stranded wire, and it will flex many times more before any of the strands begin to break. My preferance is for stranded coax. I use RG8X on my base hf rig and have had no trouble at all, even when I cranked out over 2500 watts out of the ameritron to cut through the QRM. |

Solid core coax has lower loss than equiv. stranded center coax. The ONLY purpose for stranded center coax is flexibility, that is what it was designed for. Such as when using a rotor and beam or in a magnet mount mobile setup. Except for that, do not use stranded core coax. |

We use mostly solid core on 460 meg systems. I never seen any real diffrences but my guess would be 833 is right. Cheep coax is not a good investment ive been burned many times tring to save a buck ..... ok i got some radio shack .... should have known better. |

Look at it like trying to pull a car out of a ditch.
Would you rather have one big rope, or maybe 4 or 5 smaller ropes braided together.
I personally like the stranded stuff. Like others have mentioned, it's good jumper material and is flexible. Flexibility is something you want with coax. Especially running it in windows, up under floors and under vehicles and such. Nothing quite like putting an antenna on your vehicle, running a nice straight line under it, only discovering you have to make a sharp turn due to the driveshaft or muffler being in the way. |

You would have a fit if you had to work with 2INCH HARDLINE ...... |
