Yes for the 3.65GHz band, antenna gain does matter, because the band is EIRP restricted. For instance, for the XR3, if you look on the grant: https://fjallfoss.fcc.gov/oetcf/eas/reports/Eas731GrantForm.cfm?mode=COPYRequestTimeout=500application_id=930658fcc_id=SWX-XR3B The maximum output (in

My system is fully licensed.How did you get your combination of XR3 + Routerboard 400 series + Mikrotik RouterOS 3.x + whatever antenna certified? What's the process like, and how much did it cost?Or did you just buy the kit from someone else who went through the certification process? If

I think the confusion on this comes from the fact that for the P90 licensing process, only the transmitter information is collected. Remember that even with Part 90 devices, they still must comply with Part 15 requirements for unintentional radiators. This is covered with a Declaration of

Other vendors of 3.65 GHz gear told me size doesn't matter. I guess that's what I get for listening to that phrase, no matter who's right. ;-) - Mike Hammett Intelligent Computing Solutions http://www.ics-il.com -- From:

Lower your transmit power, duh. You go a hell of a lot further with a 0 db radio and 36 db of antenna than 30 db of radio and 6 db of antenna. That do you think negative db values are for? - Mike Hammett Intelligent Computing Solutions http://www.ics-il.com

Who has the final word on this? I've been told by testing laboratories that do testing for the FCC that this is not the case... They said if the radio card (5Ghz when I asked but for this discussion it doesn't matter) had been approved with an antenna then you could use the same or less db

As per the FCC only the anufacturer can make the determination which antenna is similar in specifications. Otherwise it needs FCC certification as a system. That was from the horses mouth about 18 months ago Bob Sent from my Verizon Wireless BlackBerry -Original Message- From: Scott

That is my understanding as well from talking with a certification lab. Lower and equal gain antennas of same type as certified are allowed to be substituted by the manufacturer. /Eje Sent via BlackBerry from T-Mobile -Original Message- From: lakel...@gbcx.net Date: Sun, 8 Mar 2009
