Jeff, I too, have had issues in the past with Cablewave products. Specifiaclly when buried, or run up a tower exposed to the elements. I build AM directional facilities. No matter what lengths you go to to keep a buried line "dry" (mine are usually buried in a piece of sched. 40 PVC pipe) water entered through the outer conductor. On a tower a rigger sometimes nicks a jacket while working.... water then gets between the jacket and outer conductor. With Cablewave it always caused problems.
Seems the Cablewave method of edge welding the outer conductor was never 100% water-tight. Any nick in the outer jacket usually resulted in water getting into the foam. It has gotten better of the years. But my money is on the Andrew product, no water yet... and I always install my own connectors. Also our local ham assoc. bought some pre-fabbed jumpers from a guy in PA (to remain nameless). He used crimped connectors. After moving the rack around a few times the ends loosened and caused mucho problems. I put the old superflex jumpers we had made back in the circuit, and the problems went away. An old engineer once told me if you need it done correctly the first time, you better do it yourself. Then you only have yourself to blame if there are problems. Just my 2 cents... mike -----Original Message----- From: Jeff DePolo [mailto:[EMAIL PROTECTED] Sent: Friday, February 18, 2005 4:27 PM To: [email protected]; [email protected] Subject: Re: [Repeater-Builder] Re: Andrew Valueflex vs. Superflexible Jumpers Valuflex is the nickname for the slightly-lower-cost line of pre-made Superflex jumpers from Andrew. Valuflex jumpers use a machine-installed connector (most are crimped on), not the usual screw-together connectors that you would buy normally. I've used them a few times, but don't regularly buy them. I prefer to make my own jumpers; I've had problems with factory-made jumpers from both Andrew and Cablewave in the past. --- Jeff On Fri, 18 Feb 2005 11:36:01 -0600, Doug Zastrow wrote > Hi Mike, > > You are right, ValueFlex is NOT in Andrew Catalog 38 nor anywhere to > be readily found. > > I was shopping the A/F CommSupply Catalog and found the ValueFlex > jumpers on page 53.
