I'm working on installing my first 160 receive array.
I don't have room for traditional beverages. Ground mounted receive
loops like the K9AY array will not be a good solution as I have a large
deer population that would end up tearing it down. We had an 8 point
buck with xmas lights hanging off his antlers so I don't think loops
would survive
As I go through the design I'm trying to determine if I should use a 75
ohm system (the most common due to cheap rg-6 coax I suppose) or a 50
ohm system. I have plenty of rg-8x coax laying around and I could use a
remote coax switch to get all of the signals (4) from two reversible
Beverage on Ground (BOG) arrays. I would prefer to bring in a single
coax to the shack vs 4 separate lines.
Will a 50 ohm system play well with the available pre-amps. All of the
pre-amps I have found have F-connectors which leads me to believe they
are setup for 75 ohms. If I go with RG-8x/50ohm matching transformers
do I need to consider a 50 to 75 ohm transformer before going into the
pre-amp?
What about the output of the pre-amp into the 50 ohm input of the receiver?
Thanks in advance.
