For the AP you might want to consider the Scala TY-900, it is only rated 12 dBi but in my experience it will perform as well as the other antennas on your list, it is also very ruggedly built. You may see it listed as 10 dB but that’s dBd, add 2.15 dB for dBi.
There is a version with a radome (RY-900B) if you want to eliminate icing issues, it’s around $450 though. You will see a lot of these at SCADA sites for power companies and railroads. http://www.kathrein-scala.com/catalog/TY-900.pdf Even the non-radome version is probably too expensive for the client end.

I started out thinking PTP900 900 MHz had no place in my network... then I found more and more people who wanted to get anything they could get. This grouping of homes only has access to satellite or dial-up. Of the 4 customers who want to buy the "1.5 Mbps" service, 2 are on dial-up and 2 are on satellite. I don't want to provide slow service, but I also don't what to leave 4+ possible customers. Maybe when the PMP450 900 MHz hardware becomes available I can upgrade them. -Chris On Mon, May 11, 2015 at 8:09 AM, Andy Trimmell <[email protected]> wrote: Nowadays for me I wouldn't deploy a 900 AP because it only serves 4Mbps total. I have people complaining that 5Mbps isn't fast enough right now. They might be begging now to have "something" but in the end you'll be the bad guy with slow interwebs. Sorry if this didn't sound positive for monday but the 900 struggle is real. From: Af [mailto:[email protected]] On Behalf Of Christopher Gray Sent: Monday, May 11, 2015 8:00 AM To: [email protected] Subject: [AFMUG] High Gain 900 MHz Patch Antennas? I'm looking for recommendations for high-gain patch antennas to be used with PMP100 900 MHz gear. I have a tight grouping of potential customers that could be covered with a beam-width of only 15 degrees (I'm not trying to go that tight, just mentioning it). I figure I'd use the same antenna for the AP as well as the SMs. These are ones that caught my eye: a.. Super-Stinger: 13.5 dBi, FtB 15 dB, VSWR ?, 39 deg b.. KP-900-13-45: 13 dBi, FtB 25 dB, VSWR 1.5, ? Deg c.. ARC Wireless ARC-PA0913B01: 12.5 dBi, FtB 25 dB, VSWR 1.5, 42 deg d.. Laird Technologies R2T9-12: 12 Dbi, FtB 21 dB, VSWR 1.5, 45 deg The list is in order of stated gain. The Super-Stinger is the highest gain unit I've seen, but I don't like how low the stated front-to-back noise radio is. Also, I like the ability of the others to be rotated to change polarity if necessary. I've read good things about the M3 and KP yagis, but in New England we do get icing every year. I'm hesitant to install a yagi and have dropped services next winter. So,are there any good reasons to pick one of these over any other? Are there any good reviews or recommendations for high-gain patch antennas? Thanks - Chris
