Coax Cable (was VHF anomaly) - almost finished
Coax Cable (was VHF anomaly) - almost finished
Hi, All, Getting close to ordering, I thought this exchange on SSCA's forum might shed some light as to the direction I'm leaning - - sorry that the "quote/quote" stuff doesn't show up like in the forums, he Quote:

strong 214MilSpec recommenders, but the vendor, with whom I've been in contact sez this about the LMR400DB (me "", his below inline): Given the application, I'd think the stranded best, as it tolerates tight bends better, no? However, flooded apparently answers the water issue. What's the turn radius on the 400DB? ****installed 1 inch...repeated 4 inch I certainly like the propagation in the 400 better, but there's a great deal of sentiment among those I've been polling to get this far that milspec is the way to go. Aside from the propagation, what would be the arguments against vs the flooded 400? ****it is weather tight...RG-213/214 is not!!!!***** So, given all that, I'm inclined at this point to go his way. 1" turn radius certainly is manageable, and I'm not likely to have coils (the 4" reference). This is also pretty affordable - the installed factory end and 80', plus another silver body 259 (shell and pin teflon), is all of 82.55 shipped. I'm also quite happy to take the time to do the indoor termination right. Do I hear informed arguments against this solution? Thanks.

They are using RG-214 and I would too unless weight and cost were an issue. The connector soldering and installation instructions were excellent in my opinion. |

"Popeye" wrote in message ... 0.3 dB per 100 feet: http://www.timesmicrowave.com/content/pdf/lmr/40-43.pdf The LMR series cable is the best flexible coaxial cable you can buy. We use it to over 20 GHz in long runs on a moving gantry. It has excellent phase stability +/-1 degree and low loss. Just because a cable has an RG designator does not make it "mil-spec" and "mil-spec" does not mean the best for all applications. Look at a smaller diameter LMR cable, it's a modern cable not an RG cable designator from the 1950's. |

Well, it's over - I've ordered the LMR-400-DB. The smoking gun was in not
only some conversations in various places, but the specifics of what makes this one waterproof found in http://www.timesmicrowave.com/content/pdf/lmr/22-25.pdf FWIW, I dealt with Joel Knoblock at therfc.com, a very helpful Ham (the site concentrates on Hams, but does a lot of marine business as well). Ordering was via an RFQ, insert the quote number in the box, and off we went. So, thanks to all for the various inputs. I'm ashore (well, technically, I'm under way to where we'll be docked when we're ashore) until mid-January, but will be back at it when we return, installing new chartplotter (old one's getting too small for our aging eyes), GPS (old one's sometimes flaky), maybe AIS, high output alternator in Delco 10-DN format, new gelcel spotlight batteries, new helm VHF (undecided as yet what that will be), winch parts, rubber feet for the Honda eu2000i, rebuilt injectors for Perky (never been done that showed in the records with the boat and certainly not by us, yet), rewind spring for the revived Johnson 15, shaft kit for one of the Jabsco raw water pump spares I have, and perhaps some other stuff we'll trip over in our meanderings. Catch y'all later... L8R Skip and crew -- Morgan 461 #2 SV Flying Pig KI4MPC See our galleries at www.justpickone.org/skip/gallery !

Meanwhile tinyurl.com/flyingpigspot shows us at anchor tonight just before we go in to our dock for the month we're back in the states. I can't turn it on for that segment, as it's a surprise to the home folks - but the fiction, backed up by our always turning it off after it's stabilized at anchor, of our being here for the much better wifi and beachcombing will let us get away with it until we've landed :{)) L8R Skip, off to bed -- Morgan 461 #2 SV Flying Pig KI4MPC See our galleries at www.justpickone.org/skip/gallery !
