Title: LMR 400
Post by: sknOOb on December 30, 2007, 08:05:59 AM

Does anyone know if LMR 400 is a good coax choice for receive only in a 75 ft run as far as loss is concerned?
I live in an area where we get our asses kicked by bad weather and extreme cold and im not having much luck with rg style cable.
Any other coax that would work better?

to answer SKNOOB's question: don't worry about loss on recieve. Its only important when transmitting. But for low loss LMR 400 is a good choice. Try RG-213 though....it might be cheaper.

You're the one who dosent know the difference between 5.8 ghz and 5.8 mhz.....but i digress.

Loss is equally important on TX and RX.  Those who work weak signal stuff on VHF/UHF i.e. some satellites, especially EME, SSB DX know minimizing loss is of the utmost importance.  Some even install hardline for better loss figures than 9913/LMR-400 or LMR-600.  Mast mount preamps help a lot, too.  A lot of this is moot though if you stick to VHF or below.  The differences at lower frequencies is so minute it's as if there was no difference at all.  The higher the frequency, the greater the loss and the greater disparity you're going to see between types of cable.  You get up to 2.4GHz and the difference could be as much as losing half the signal.

I decided to go with the LMR 400 DB.
The hard line stuff is very nice but a bit of overkill for what im doing and the LMR is more in my budget.
Thanks for the feedback.

And it sucks putting a pl 259 on hardline......
