I still don't know what SAC is, and now what is S&S?
They are tested up to 2-3 bar- 3 bar for comparison is the upper limit of central heating systems, you can go back to outdoor cable joins years later (as I have)- unscrew them in seconds & they are clean & dry inside & have better RF characteristics.
There's no need for self amalgamating tape for outdoor joins as the author of that pdf thinks- that's one of the reasons why you pay a lot more for them & the tools needed to fit them, the threads are more precision compared to cheap f connectors & the grip on the cable is rated at a high level without damaging the coax.
Price wise (trade prices - not retail) they are a lot dearer than cheap screw on f connectors plus the cost of the fitting tools - but using them every day, the higher price makes sense, if you are just fitting a few then good screw on f connectors & self amalg tape for outdoors etc.. make sense.
We've got several brands including Thomas & Bett's nearest equivalent which I like anyway & price wise are near enough the same if bought trade- there's several others (see webro's site) & you can pay a lot more for even higher spec' for vsat etc.. & prices for bigger core can get really silly (over £20 each & keep going...) but then so can the coax.
You can get better quality screw on f connectors - more solid body*/ more precision f connector side screw thread / sealing ring inside that seals at the dielectric & has been said ... you need to match it to good coax - a good tight fit without damaging the coax- keep the cooper braid short so the thread seals on the coax outer & avoid cheap coax, even if it fits well.
There's also crimp on f connectors with or without sealing rings & gel - I don't like crimp on but if you do use them get a good brand & with sealing rings & gel & several other types.. Webro list a
self install one you just push on with no tools-(tried them - don't like them tbh)
Avoid cheap thin screw on f connectors- even if you get a good fit on the coax, they can split plus the f threads are usually tooled to be loose.
(*they don't look bad on the link on post 1# for screw ons - but ask them if they have sealing 'O' rings inside- you can buy sealing rings btw)
