So you are wanting a dual pol panel with N male connectors? Steve Barnes RC-WiFi Wireless Internet Service

The trouble with the Powerbridge is that it has the radio built in, and is thus an Ethernet hop away from the switch (probably a Routerboard), and one more active device to manage. Also, since a Ubiquiti card drives the radio, it can only run in Airmax or 802.11 mode, not however the Routerboard might be able to drive it (for exmmple, MT's new nv2 mode). What I want is the Powerbridge's antenna by itself! That would be exactly what I'm looking for. ARC Wireless makes a "panel antenna for IES", but again that presumes a Routerboard-class radio built in. Would it work with just, uh, cable jumpers to an outboard radio? BTW I'm using RadioMobile to calculate paths, and while the one in question "works", it is not a perfect one; it shows some Fresnel zone interference along the way, since it's hilly terrain. I may have to raise or lower the antenna a foot or two to avoid nulls. At 7/30/2010 11:59 AM, you wrote: >Yea, it's wrong.
