Spectrum analyzes

Hi, 1st thanks for taking the time to look at this post.

I have a wireless solectek wireless omni antenna that i did a spectrum analyzes on it and i have a question about what i got back.

now keep in mind that the customer antennas were also on so that data below is distorted.

1. should i be looking for numbers closer to zero or higher negative numbers when looking for less interference on each frequency?

2. how does th peak compare to the current/avg interference?

Freq Interference Interference Level
Cur Avg Peak
5745 MHz -64 dBm -62 dBm -52 dBm
5785 MHz -66 dBm -67 dBm -65 dBm

Below is the same chart in advance view.

What does N I/N mean and what sould i be looking for here in terms of numbers that equal less interference?

Freq Interference Interference Level
N I/N Total
5745 MHz -82 dBm 18 dB -64 dBm
5785 MHz -88 dBm 22 dB -66 dBm


thanks very much, P
