It doesn’t seem like you could buy the materials to make such a cable for $4, then there’s the labor. How do they do it?

How much did the cables cost you? From: Mathew Howard Sent: Thursday, January 14, 2016 6:56 PM To: af Subject: Re: [AFMUG] 900mhz PMP450i with dual polarity panel Yeah, SMA on the radio. No, those antennas didn't come with cables, I'm guessing they can supply cables, but I didn't think to ask... the antennas appear to be intended to use with ubnt Rockets (they have a holder for one built on), which would use the same connectors.

I suspect that if you ordered a large enough quantity to get a decent shipping rate, even after adding jumper cables, it would still be a bit cheaper than the Cambium yagis. I did do a little testing with V/H... but it was kind of inconclusive, the signal level was only slightly weaker, but when I ran a link test, it was much worse - about 45m down vs 90m, I tried holding the Cambium yagi at a 45 degree angle and it was pretty similar results - 70m vs 90m and slightly weaker signal. I'm not sure if that was anything to do with the polarity being mismatched, or if it was just that H/V doesn't work as well as slant at that particular location... also, I was just holding thing antennas for the H/V tests and they were mounted at +/-45, so that could account for some of it too.

From: Mathew Howard Sent: Thursday, January 14, 2016 3:36 PM To: af Subject: [AFMUG] 900mhz PMP450i with dual polarity panel Fresh from China :) I tested it at two different customer's houses, and signal levels were consistently within 1db of the Cambium yagis. Not quite as clean of a package as the Cambium antennas, but it works and it's not a yagi... I did have to replace the bracket to make it dual slant though.
