UAP-Outdoor: Set "Antenna Gain" - what does it mean?

For the UAP-Outdoor there is a field named "Antenna Gain" in the web GUI.

I'm not sure what it actually does, but my guess is:

Tx Power - Antenna Gain = actual output power at RF connectors


Is this correct?

Tx power is the 'actual output power at
rf connectors'. Tx power + antenna gain = EIRP
from the antenna.
This allows the radio to calculate the
EIRP and limit output to legal levels. Dave

Tx power is the 'actual output power at
rf connectors'.
Tx power + antenna gain = EIRP
from the antenna.

This allows the radio to calculate the
EIRP and limit output to legal levels. Dave


Using the values from the picture I attached and calculating the way I assumed it would work, "actual output power at RF connectors" should be (20 - 6)dBm = 14 dBm which gives an EIRP = 20 dBm = Tx Power. This way the value entered into that field would be equal to EIRP which I would consider useful since the user doesn't have to calculate again until the antenna gain changes.

Using your formula would give us (20 + 6)dBm = 26 dBm = EIRP which then is limited to "legal levels" that are not shown in the GUI which leaves the user with an uncertain actual EIRP.

Are you sure it works this way? Sounds like a funny UI design decision.

I apologize; you are correct.

The 'Tx Power' is the EIRP; subtract
antenna gain to derive rf output power. Dave

hi,

 

tx power = 20 and antenna gain = 6 for unifi outdoor is correct? how about the "max: 28 dBm"?

if i can set it to 28 dBm and antenna gain to 6 dBm

Then your EIRP would be 34 dBm. Is that legal for PtM in your country?
