Cables and connectors are not cheap when manufacturing.  PITA.  Hmmm.
SMA on the radio?

Did the chinese antenna come with cables?

No, they don't come with cables - those are permanently attached to the Cambium 
yagis.

  Possibly.  I have the mold for the cover.  Back would be aluminum.  Just need 
a nice pocket that slips over and interfaces with the radio.   Does the radio 
come with cables?

  Slip on stinger would be way faster.  Could you match the price?

    I would have to have a large commitment to meet that price for a slip on 
stinger version.

    This is the antenna: http://www.lanbowan.com/ANT915D12C-DP.htm 

    The antennas themselves are pretty cheap - they charged me $41.61/each, but 
shipping was quite expensive (they sent them DHL - there are obviously cheaper 
ways). 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.

      What’s it cost?

      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.
