You are not understanding what you are measuring. If you place your transmitter 10 feet away from your analyzer you are going to see a much different result. That device is measuring the signal strength as it sees it. The only way to measure output power is by a direct connection.
Anytime you see a negative (-) value that means receiving signal strength.
You can find various calculators online that will show you some simple things, like for output power 100mw = 20.0dBm, and 200mw = 23.01dBm. Again, this is output power. Remember it takes basically 4x the output power (400mw vs. 100mw) to double the effective range. Every 6dB doubles the range - either via transmitter output power (26dBm = 400mw) or by having a 6dB increase in receiver sensitivity.
