N_Jay said:How many feet?
Figure the losses and then decide.
On short runs you may not notice the difference.:wink:
I love people who make absolute statements without enough facts!:roll: :evil:
"100% without a doubt you would see a HUGE difference going from 6 to LMR 400"
I'm crazy? (Well maybe so)scanner_freak said::lol: :lol::lol: :lol: :lol: Which is why I provided the calculator:roll: I dont' care if it's 5'..He would benefit stiching cables..2.4 DB not enough to worry about? You're carzy...
scanner_freak . . . . My N to BNC adapter has .02 db of loss..Now that''s not enough to worry about..[/QUOTE said:Looks like we were editing at the same time.
And just how did you MEASURE your adapter???
Agreed, good link. (I keep 'misplacing' it...lol)N_Jay said:http://www.timesmicrowave.com/cgi-bin/calculate.pl
(Nice link, thanks)
If CSL126, or anyone, orders it 'pre-terminated' you don't always have to use adapters if you tell the place you're getting it from what you want at each end.N_Jay said:LMR-400 will probably need an adapter and jumper on the radio end adding an extra 0.5 to 1.0 dB of loss not included in the above.
N_Jay said:I'm crazy? (Well maybe so)
But that aside;
adding 2.4 dB to a signal you are not getting will leave you with a signal you still don't get good enough to listen to.
adding 2.4 dB to a signal that is real noisy will leave you with a signal that is still fairly noisy.
adding 2.4 dB to a signal that has just a little noise will leave you with a signal that has just a little less noise.
And at 5 feet, your connector losses for either cable outweigh the loss of the cable, so I think you can join me in being crazy (heck, you might even be more crazy)
I was referring to the fact that LMR-400 is usually a bit stiff to get to bend to where you want it.RISC777 said:If CSL126, or anyone, orders it 'pre-terminated' you don't always have to use adapters if you tell the place you're getting it from what you want at each end.
I don't know what the loss was on your "OLD" RG-6 was before you put on your "NEW" LMR-400.scanner_freak said:The 5' reference was to him benefiting even if it is only 5', which, he will benefit by having a much better cable..My adapter specs were the manafactures tech specs which came with the adapter. I'm not going to argue the reception issue. I know what going from RG-6 to LMR-400 does at 50', so I am positive what it will do at 75 or 100'
Well OK, but I don't quite get where the 5' is extra or whole length. (maybe what your wrote is different than what you meant? We have all done that)scanner_freak said:The 5' reference was an indication to me that you were being irrational in your answer.
Why would anyone want to swap out 5' of RG-6 for 5' of LMR-400 on a scanner?
Not 5' of cable total, 5' addition is what I was talking about
Well, it does matter because the opposite is also true, with a bad antenna, the cable is irrelevant.scanner_freak said:No one has even asked what type of antenna he has?
a taller mount (if local obstructions are the issue).
Does it matter? Without the right cable what good is your antenna...
Yes, and true, but "better" in general does not make something "better" for the particular situation.scanner_freak said:Sorry to be such a pain, but your "blanket" recommendations just don't "cover" everyone.
Yes they do, I don't care what the situation is, LMR-400 is much better cable in more ways than just signal loss..
Very true, if you bend it, it definitely wants to stay where you "left it." That can be a good or bad thing sometimes. Besides the fact it's 3/8" (which so is the 9913).N_Jay said:I was referring to the fact that LMR-400 is usually a bit stiff to get to bend to where you want it.
If you can, then no jumper is best.
Just to clarify, "RG" numbers have ALWAYS been a general type specification and have NEVER indicated a specific quallity level.mastr said:Another factor is the myriad of so-called "RG6" cables in use. "RG6" has become a catch all nomenclature for any 75 ohm cable of about .270 inch diameter.
You mean LMR-600?RISC777 said:Originally Posted by RISC777

Now that UltraFlex with the stranded core, that stuff is way cool to work with. Though I once almost bought a run of the flame retardant just to have the outer orange sheath. :lol:
[ off-topic: N_Jay, you ever worked with any -600? ]
