Question about SF-95 signal finder

[Dah-Henny]

I'm not a professional (duh!) and usually install my equipment with the yelling at each other method, which works. Anyway, I bought this little dink SF-95 meter that hooks up between the dish and the receiver. The receiver powers it with 18 volts I believe.

Last year's model SF-95 had a port to hook up an aux power supply using 2 9v batteries in series.

The 2009 model does not have a port for such a function.

HERE'S MY QUESTION:
Is it feasible for me to hook up 2 9v batteries in series and hook directly to the cable port of the meter to power it? I know I can use the receiver's power, but would rather not.
If it's feasible, positive would connect to center core and negative to the outer braid???

Yes. Correct.

Remember, some DP LNBFs taking 400-500 mA, so your battery could be drained quickly.

Thanks P.
You're all right!
I'm gonna disregard everything I've heard about you now!..........just kidding

Smith P, I'll be hooking to an eastern arc lnb; how long will the batteries last?

 

[Smith P.]

Check capacity and max current of those. If you willing carry heavy box - use 10 or 12 "D" size in series.

 

[Dah-Henny]

Thanks, I'll check.

Or take your car's battery for setup the dish.
