75 And 50 Ohm Connectors In Same Listening Chain ?
Hello,
Should have asked this also in my previous post re 50 or 75 ohm coax, but I guess it is probably better to start a different thread. New at this, so please pardon these very basic type of questions. For a receiving only application, 30 MHz on down: Putting up a new Inverted-L receiving antenna. Radio, Balun, Lightning Arrestor use the 259 type of plug which I guess is nominally for 50 ohm systems. I can go with 75 ohm BNC connectors for the main coax run, but am pretty well stuck with the 259 type for the already purchased units I noted above. Intuitively, I guess I would like (all) 75 ohm connectors if I am using 75 ohm coax. But, for 30 MHz and lower listening, would I even notice any difference, probably ? Is any received signal lost, or reflected back, at these 75-50 ohm junctions ? If meaningful, any way around the problem ? Thanks, Bob |
