Default Coax Quest. ?

Hello:

Don't have a good feeling for the significance of this:

For a receive only application, using coax from the Balun of a simple
outside antenna to the receiver,
is a loss of, e.g., 2.5 db "meaningful" ?

Specifics would be 100 feet of RG 58 at 30 MHz

Or is it worth the extra $ to go to a less lossy coax (application would
always be for receive only)

BTW: R/S Coax a decent quality ?

Thanks,
B.


Don't get the R/S coax. If you can handle the aluminum wire shielding of
the cable TV RG-6 coax , use that. Less loss and the 70 ohm vrs the 50 ohm
is nothing to worry about. I usually use the RG-8X coax for frequencies
below 30 mhz instead of the rg-58. Not that more expensive.
