Calling the RF engineers of the group:
I’m getting frustrated by my Google-fu not returning results that I particularly understand. I’d like to know the RF power (wattage) of my antenna at the point where it connects to my RTL-SDR dongle.
My current setup (cue ASCII art):
1/4 wave ground-plane antenna (spider)–>DC Blocker–>Perfect Vision PVLA-30 Amplifier–>50’ 50Ohm Coax–>Power Inserter (with 24VDC power supply)–>DC Blocker–>RTL-SDR
Specs on PVLA-30 (from Amazon):
950-2150 MHZ/ GAIN 30DB, NOISE FIGURE 6DB
LINE VOLTAGE 8 TO 29V DC IN/OUT, WITH POSITIVE SLOPE
CURRENT CONSUMPTION 125 mA
OUTPUT LEVEL -10DB
I’d like to reinsert my filter (ZX75BP-1100+) between the DC Blocker and the RTL-SDR, but I noticed that the RF power input is 3.2W Max. (as compared to the 7W Max on the VBFZ-1065+.) I wasn’t worried about the 3W max when I didn’t have an amplifier inline, but I suspect I should be a bit more careful about that rating with the amplifier inline.
What is the best way to determine the RF power wattage with the amplifier inline?
I do not have access to the expensive RF power meters that were being returned in my Google results, though I do have access to a Fluke 199C Scopemeter and likely a portable oscilloscope.
