There are not many out there who can do a proper, watertight soldering job up at the top of a wavering, windy masthead. Been there, done that, was not always proud of my work. Old Chief Lynn, W7LTQ, PG-13-20604 Hay, chief, did ya ever think to push the wire down the mast using a messenger to guide it, like the old wire being replaced, or a fish line? that way, you leave the end with the on deck pre installed connector on it at the top except what happens when this thing sits in the wind, and rocks with boat motion? the mechanical support for the cable/connector interface isn't there. hell, these fail on CB installs all the time (no ham i've never known ever used rg 58). . How long do hams spend sending? Rael hams use code, light duty cycle, rtty is light duty? it's 100% duty cycle at full power. Mil RG58 is good enough for most, cheap, light. Communications is our most valuable resource. it'll work. but i wouldnt bet my life on it. --------------------------- to see who "wf3h" is, go to "qrz.com" and enter 'wf3h' in the field |

Hmmm, another flatlander, who thinks Marine Electronics is the same as Ham Radio...... ROFLMAO! do much radio work? RG-58 comes in a whole pile of different forms, of which, some are prefectly adequite for some specific Maritime uses. It is enherently just as reliable as any other coax type, when installed properly. and you're missing the point. There certainly are some forms of RG-58 that have poor shielding, but there are also some forms of RG-58 that provide for 100% shileding, as well. Better go back and look at a Beldon Catalog again...... kinda missed the total picture, didn't you? part of the reason thicker cables work with pl 259's is the fact that, installed properly, the jacket seats itself in the connector. this functions as a stress relief and stabilizes the connector. rg58 is too thin to take advantage of this. and, again, the thicker cable has a mechanical advantage when inserted into the connecter since vibration is reduced, thereby reducing stress. Run Length and Frequency certainly are part of the list of things that determine the suitability of any Coaxial Cable installation. Obviously, you have never hear of the UG-174U Adapter..... and what makes you think that a PL-259 is the "Be All, and End all" of Marine Radio connectors? Me who wonders where these guys come from...... ever been on a boat? how many pl259's are out there? how many of them have adapters? answer: almost none. as to the adapter, it's unreliable since the mechanical advantage is not present over the entire length of the jacket/connector interface. --------------------------- to see who "wf3h" is, go to "qrz.com" and enter 'wf3h' in the field |

Am I missing something here? Surely the RG-58 wouldn't be attached to a
PL-259 without a UG-175 reducing adapter, would it? Is it being said that even with the UG-175, there is insufficient strain relief? Thanks for the clarification. Chuck |

Is it being said that even with the UG-175, there is insufficient strain relief? in my opinion the answer is there is insufficient strain relief for critical applications. the jacket of thicker cables, such as rg 213, when inserted into the pl 259, provide quite a bit of support for the connector. --------------------------- to see who "wf3h" is, go to "qrz.com" and enter 'wf3h' in the field |
