You're not the only one to recommend them, so that may well be the best bet. Another nice feature from Arc is the ability to use the enclosure system to build a high-performance 900 MHz CPE, which I may want in some heavy woods.

Re: [WISPA] MIMO 5.8 GHz panel antennas?
Yes you can run a cable through the bottom of enclosure and to the antenna. Works fine. I've done it - think of it as two antenna connections that have no change of water entering because they are inside. No need to even seal them. The ARC panels work very well. Shove a rocket in that enclosure and you will be happy with the results.

Re: [WISPA] MIMO 5.8 GHz panel antennas?
Fred, The Arc Wireless dual pol panel is a great value with embedded genII enclosure. You have to use the enclosure for the mount to screw on to the antenna. You can still use cables to an external radios, its just that your cables are inside the enclosure, and pass thru the case holes. That actually can be a benefit because it adds waterproof protection. The good thing about teh Arc system is that even with teh enclosure it is very affordable compared to other antennas of similar spec. The ARC has almost 40db of isolation between ports, which makes it best of class performance for MIMO. You are looking at about $150, but performance will be very good.

Re: [WISPA] MIMO 5.8 GHz panel antennas?
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.

Re: [WISPA] MIMO 5.8 GHz panel antennas?
Fred have you made a good quality link with Mikrotik using N-MiMo I own a set of MT units with R52HN cards that drove me crazy for about 3 weeks. Never made the MiMo work real well with MT. 2- PacWireless dual pol 2 ft dish with MT a both ends 12 miles. Could make them work as 802.11a but the N was very hard to get working right and never got the speeds that I needed. Was told that I had bad dishes or cables and not aligned right by company that I got the setup from after they worked on them for 4 hours one day remotely. Changed the radios to a old set of RadWin radios I had and went to 49MB in 15 seconds. Never got more than 18 meg out of the Mikrotiks. So now I have some extra MT 411ah cards that I will put in a AP somewhere and some R52NH that I don't have time to mess with. I will just use the RADWin stuff for critical links and UBNT stuff for secondary links.

They have a Powerbridge M5 that includes a 25 db MIMO panel. Regards Michael Baird I wonder if any of you have experience with 5.8 GHz MIMO antennas. I'm trying to design a point-to-point link, about 10 miles, that will carry a high percentage of a whole network's backhaul. So I'd like it to go at about 80 Mbps, MCS 12 in 20 MHz. The UBNT SR71-15 card can plug into a Routerboard and thus feed two antennas, or a dual-polarized antenna. I'd rather have one antenna than two. I can find dual-feed 2' dishes, but they're on the large side, with wind load and visibility issues. And I see a lot of single-feed panels, which can handle 11a-type traffic. I can run Ethernet into an external radio that comes in a panel, but that adds a hop and more complexity, and frankly most of the specs don't match the SR71-15's. There will be at least three antennas at each end, possibly four (backhaul plus local access). MiniPCI radios in, say, an RB600 seem easier to deal with. But who makes a standalone 5.8 GHz dual-polarized panel, something the 22-25 dB range (13-16)? UBNT makes MIMO sector antennas, and makes panels with built-in radios

Mikrotik N has been disappointing to many. Has anyone had good results?

Never made the MiMo work real well with MT. 2- PacWireless dual pol 2 ft dish with MT a both ends 12 miles. Could make them work as 802.11a but the N was very hard to get working right and never got the speeds that I needed. Was told that I had bad dishes or cables and not aligned right by company that I got the setup from after they worked on them for 4 hours one day remotely. Changed the radios to a old set of RadWin radios I had and went to 49MB in 15 seconds. Never got more than 18 meg out of the Mikrotiks. So now I have some extra MT 411ah cards that I will put in a AP somewhere and some R52NH that I don't have time to mess with. I will just use the RADWin stuff for critical links and UBNT stuff for secondary links. Steve Barnes RC-WiFi Wireless Internet Service -Original Message- From: wireless-boun...@...
