Still easier than having to use blasting caps to find the ends of a broken conduit under the finished concrete floor in a new RADAR site. An old fish tape & blasting cap pushed as far as it would go and BOOM!!!. Then repeat for the other end. Then they used a jackhammer to break out the concrete between the huge floor divots to install new conduit. The electrical contractor had failed to tie the conduit to the rebar & wire mesh before the pour. :)
Or driving ground rods through permafrost in Alaska. We drove 60' of rod and used three tanks of Acetylene to heat the rod to get it through the ice layer outside a military radio & TV station at Ft. Greely.

I am glad I didn't have to use blasting caps as TDR. But it does sound kind of fun if you didn't have delivery pressure on top of it.
Sounds like good work. But not up the Giant Rat's standards, I'm sure.
Interesting that he portrays himself as young and uses that reference. Very curious. Maybe he's old and a failure and not young and a failure as he claims.
Those were the lowest grade, next to screw on fittings. They had the highest leakage, and shortest service life of all the connectors I ever tested. Did I mention that we bought 50,000 feet of RG-59 & RG-6 per month for cable installs? We were using the Raychem for new work & repairs in the mid '80s. They were the best we could find, both for drop, trunk & feeders. They didn't need a boot, and you would break the cable before a connector would pull off, if installed properly. We had to keep a close eye on radiation to prevent one of the midband channels from interfering with airplanes. 95% of the problems were those half assed separate ring, three cent connectors.

He was a cable grunt when Time Warner built Cube in Cincinnati, so I'd say that he's at least 50 and still a very angry failure.
That RADAR site was at Ft. Rucker, and the problem was in the area reserved for the new IFF hardware in the mid '70s. Weathervision was assigned to the space while I was there, but were were in the process of moving to another building when I was told I had orders for Vietnam. I ended up in Alaska instead. Two weeks later that AFRTS station in Vietnam was overrun and the engineers killed. They shipped parts of the transmitter that survived the gunfire to the station in Alaska. :(

Inspire you to clean up your act. However, judging by your response, you're not worth the time and effort. As you were...

That I am. And I am going to stay that way too, idiot.
I will. In person only, and you have to give your info first. Feeling paranoid yet? That's right, asshole. I would use the info to make the meeting less savoury than you expect. You would end up in the sewer, where you belong, and where your mind already is.
Are you seeing the reason why Usenet is anon yet, dumbfuck?
6.2.2 Axial Pull Force: The male ?F? pin type connector, when attached to cables manufactured to SCTE approved standards, shall withstand a minimum axial pull force of 40 lbs for outdoor and 30 lbs for indoor applications when tested per ANSI/SCTE 99 2009, Test Method For Axial Pull Connector/Drop Cable.
I doubt that the crimp connectors could pass the test.

Correct. I supplied the minimum necessary for you to notice that there is a problem. Think of it as a mirror in which you see the results of whatever it is you're trying to accomplish. You are trying to accomplish something, or you would not expend so much time an effort on something so trivial as insulting everyone within range. From your response, it wasn't very difficult to determine that you're not responsive to any feedback, criticism, or suggestions. I know when to give up, which is precisely what I've done.
Incidentally, the mirror isn't such a bad idea. Look in the mirror and ask yourself if what you see is what you had once intended to become.
Not true. Had you responded with even the slightest interest, I would have burned considerable time and effort explaining my observations, offering recommendations, and generally trying to be helpful. (Punch my name into Google Groups search and see for yourself.) You can start the cleanup exercise by losing the profanity. If you claim to be a knowledgeable professional, the first step is to act like one.

You probably have no idea how much you reveal about yourself with such comments. Your search for self-esteem is the surest sign of its lack.

Good story. It brought to mind a promotional video I saw for a company that had a process called explosive bonding (of dissimilar metals). They must have been too cheap to rent lights, so they did the demo outside on an old wooden table. It was two guys in overalls and, I swear, they could have retitled it "Gomer and Bubba Find Some Dynamite" and nobody would have noticed.
Sorry Jeff but I never used my connectors to support my cables. You may be right but completely irrelevant to me. To me F connector and good connection shouldn't even be used in the same sentence. They are what that are, cheap connectors at best that uses the center conductor of the cable for a contact. Now that is Yech. Heat shrink has nothing to do with the pull test or hiding poor workmanship but it does help keep corrosion down which is the biggest problem with F connectors. Ive never seen one pull apart except in the shoddiest of installations. One of the best things I have found to insure you maintain a good connection is to apply something like DeOxit to the connectors when you assemble them. Best done while all the parts are new.
You are correct that the problem is in the hex crimp and part of this is because they started making the crimp made on to the connector. The other part is that you have to have a special tool to crimp them. All the pictures that you showed are require a special crimp tool. If these tools are worn or dont fit the particular plug/ cable combination you will get a bad crimp. The old style that is probably
40 years old now that you could crimp the little ring with a pair of pliers worked the best. Unfortunately you can no longer get them, well I do have a few.
There little wrong with good quality F-connectors. They are generally good enough for what they were intended for. Problems are usually down to who installs them, and how.
For personal outdoor use, I always give any connectors a squirt of WD40
- both during and after installation. [I guess DeOxit would be similar or better.] After cleaning off most of the WD40, I then seal with self-amalgamating tape. Obviously, heatshrink would be better, but for me, is usually less convenient.
Mechanically, even screw-on Fs can be hard to dislodge, provided just the right amount of braid is trapped under the screw thread. However, I suppose that sometimes they might not provide the ultimate in screening.
In the UK, in the large CATV networks, crimped connectors are well and truly a thing of the past. Anyone using them (even the good ones) would be liable to be hung, drawn and quartered, and then severely punished.
The standard connector is of the 'Snap and Seal' type (and similar). In themselves, these are pretty well watertight, and the screening is excellent. It should be almost impossible to pull one off the cable.
However, it is unusual for F-connections to appear naked in the open air. The final RF distribution to the home is invariably from a street cabinet which houses an optical node or an RF distribution / line extender amplifier feeding a bank of taps/splitters. The 'traditional' cascade of in-line taps has not been used for a very long time. Under these relatively benign conditions, the F-connectors probably suffer much less from corrosion than those used on taps hanging on aerial messenger wires, USA-style. Nevertheless, there are various purpose-made short 'chunky' rubber sleeves which can be installed first on the tap ports before the cable connectors are screwed on. These seal the screw threads. Personally, I would have liked to have seen a bit of WD40 used but I never managed to drum up much enthusiasm for this as an approved practice.
No. I know for a fact that paddles were applied while a system of ours was connected. The doc should have first pulled the plug as the procedure calls for, but didn't. The witnessing engineer almost froze but the patient interface held. If it hadn't someone would most likely have died. I had designed it defibrillator-proof even though the standard did not (yet) require this.
Like where? And what particular standard? Quote, please.
