Servamatic,
Let's take a look at the facts:
A) Our tests were to analyze how these fittings stood up over time. On the tap, we placed weather boots (I believe 1/2" boots) on the ports of the tap, and then used a variety of fittings. We then placed the tap int oservice for about 3 months on the coast of California... a pretty gnarly area. Digicon's fittings by the time our test concluded... were completely corroded, allowed moisture to get inside... the center conducter of the RG-6 was corroded, unacceptable by anyone's terms. Thomas and Betts connectors were dry, sealed, and easily disconnected and reconnected.
B) Comcast (AT&T), Charter Communications, Cox, Adelphia, and all of the independent outfits I have ever worked with have ALL USED THOMAS AND BETTS ACROSS THE BOARD. I don't really care what AT&T decided on... AT&T's broadband division existed for how long? Not very... and (I may be wrong on this, but I think I'm correct) most of AT&T's broadband division was sold to Comcast.
C) Hardline adapters, fittings, ceizures, etc. are all made by TnB as well, and interface nicely with their inside wiring / drop products.
D) Hands down, TnB RG-11 fittings are the best I have ever used in the business, their environmental seal is much higher quality than Digicon. I can say that just from putting taps in buckets of water and seeing if it penetrates the fitting (again, with a weather boot).
On top of all of this...
Let's get into ingress as well as signal loss. As far as signal loss is concerned... as long as the shielding is completely deflowered and the fitting compresses it against the outside jacket, as well as the dielectric being kept in a circular form, flush with the back of fitting, and the center conductor doesn't exceed more than 3/16" of an inch from the outside end of the fitting, then signal loss will probably not occur as a result of the fitting. That being said, you could probably make a fitting out of duct tape and still not lose any signal (figuratively speaking).
HOWEVER.
The reverse path is a different story. Much more affected by leakage, much more sensitive to ingress, etc. The majority of signal leakage in CATV occurs at the tap where there are either bad terminators, or the lack of terminators, or trap filters. With today's fittings, most if not all signal leakage is zipped up, especially with weather boots and fitting savers.
So to make the statement that Digicon is superior with zero ingress, is far fetched to me. I'd have to see the setup to believe its applicability.
I don't doubt your knowledge, experiences, or education Servamatic. Simply put: I know CATV, I do OSP construction for two of the biggest CATV companies in America, I follow their standards and guidelines to the T, and we wouldn't dream of using digicon fittings if stranded on an island. Thomas and Betts products are highly developed, highly integrated, and very universal. Our company just doesn't have time to experiment any further with fittings and what not, when what we have works absolutely perfect. Our CATV system uses analog TV, digital TV, and cable modem services. There isn't any room for error, simply put.
