[Hi-zreceivingarraydiscussions] Power Over Coax Issue

[Lee K7TJR]

Brian, the RG-6  resistance is about 33 ohms per 1000 feet. We have an app
note on this but I cant locate it right now.
 I am waiting for Dick to call me back to get it for you.
   You can supply the voltage to the power injector separate from the shack
switch and then apply higher voltage
 than through the Shack switch. Only problem is then you cannot turn off the
array with the shack
 switch power switch.
 Going beyond 20 Volts through the shack switch may over current the LEDs.
 The injectors can handle 25 to 30 volts easily.
Our app note shows this and I thought it was on our web but I don’t see it
there.
 As soon as I can I will send you a copy and put it up on the application
notes.

Subject: [Hi-zreceivingarraydiscussions] Power Over Coax Issue

I just finished up the 8 Circle Array this afternoon, and it decided not to
work.

After making sure my wiring was correct, I checked the voltage out at the RX
array.

When I check it before (without the remote receiver and the phasing units
connected, the volt meter said I was getting 13.8 volts at the RX array so I
thought I was in business.

Once I connect the remote receiver and phasing units, I see that the voltage
drops to about 7 volts.

The feed line is about 1100 feet +/- of RG-6 coax

Should I be seeing this sort of voltage drop, and if so what type of input
voltage can the power over coax injectors can handle?

Thank you
