Booty, my FS meter is a digital RF sensor, and it reads up to about 1005 units, whatever the units are...I'm not sure.

 

Like most CB FS meters, it is just a reference. It read 97 with the feed line before I added a 4' jumper, and 192 after. I don't know what the readings mean in DB's either, the value just increased about 100% with that simple little change. I was surprised I saw that much change even thought I was expecting something to show up.

 

It was just reading RF field strength in the area around this meter and antenna which I have hanging near the ceiling in my shack. I have no idea what type of signal it is sensing, antenna or CMC. Maybe it is a combination of both.

 

If you have a FS meter that is sensitive enough to register somewhere in your shack, you can try the same comparison and see what you get. Let me add that neither value effected my PC speakers which usually tells me I have a problem with RF in my radio room.

 

I was transmitting on my Startuster up at 46' feet to the hub. What do you mean when you ask,
