I was speaking about modifications produced in this ROS edition: viewtopic.phpf21t144949 If I recognize this right, in theory, if regularity mode is certainly arranged to regulatory domains and you have a appropriate country setting, then ROS wont let you set antenna get value lower than required for EIRP to stay inside nation regulations.I recognize tx-power-mode arranged to anything some other than default runs the danger of damage with improper settings, but Ive also been recommended by a 3rm party advisor that improper antenna-gain can also harm the wireless credit card over period if established to 0, which Ive wondered, but havent discovered a clear explanation plenty of to believe it.For illustration, a Mikrotik LHG 5 specifications show Antenna get dBi for 5 GHz to be 24.5 ( ), which Im directed to assume this must end up being the value provided to antenna-gáin for this equipment and should not really be remaining set to 0 as observed with a default RouterOS settings.

Then go for regulatory domain name in order to be restricted to the frequency channels obtainable for your country and furthermore for the potential Tx strength you are permitted to use. Finally, put in the antennas get according to the specs therefore that the max transmit power, eirp, can end up being calculated.the increased the get you use the lower the Tx energy worth will end up being therefore that you remain inside the regulations limits. Calculate Antenna Gain How To Established CountryPer the illustration config, Im conscious how to established Country and Rate of recurrence Mode, but my issue really provides more to do about concerns with leaving the antenna-gain set to 0. Is now there anywhere in Mikrotik paperwork that actually describes that thé antenna-gain shouId match up the DBi of the specs sheet. And models are usually dBi which is custommary device for antenna get (I havent observed it written anywhere in MT papers, but this is definitely common radio stations understanding). If you dont have fun with with Tx energy table, then departing antenna get arranged to 0 wont hurt equipment, ROS will automatically back-off Tx power for modes which require various Tx profile. Leaving antenna gain arranged to 0 will just create your place illegal due to excessive EIRP. Placing antenna gain at a non 0 worth will tell the router tó subtract that get to stay with nation regulation. As antennas in little RBs, for example, are generally 2dBi, your AP will be 2dBm stronger than allowed in your nation. Oh yes. how i missed that Although i know we should provide the real gain. This conversation has definitely helped me realize much more about the antenna-gain setting and what it will, but it appears like youd want to personally calculate EIRP in purchase to number out if youré over the legal limit depending on the cellular card unless its presumed all wireless cards output would fulfill the dBm restriction with thé tx-power-modé fixed to default. Calculate Antenna Gain Code The SettingAlso, its interesting to notice that Mikrotik would not really program code the setting in the Router0S firmware for gadget versions that possess inner or non-repIaceable antennas so people with less knowing may prevent illegal dBm using the quickset function with respect to getting the appropriate antenna-gain fixed. ![]() AFAIK there is definitely no need to state it for gadgets with incorporated antenna. This would become very fascinating to verify if real since many of the products I work with have an included antenna. There can be no guide in the wiki for that. Calculate Antenna Gain Manual In TheAccording to the manual in the Anténna-gain you identify the worth of the antennas get. I was speaking about modifications produced in this ROS edition: viewtopic.phpf21t144949 If I realize this right, in theory, if rate of recurrence mode is definitely arranged to regulatory site and you have got a right country setting, then ROS wont let you arranged antenna get value lower than needed for EIRP to stay inside nation regulations.
