Sounds like Faisal may be referring to the Devo hats Energy Domes SIMPER horns?

I just want to make sure that I understand clearly what that video is 
stipulating ....

and Josh, yes there is family of sector antennas (a bit funky looking) which 
have these specs.. + a few other very interesting design features.  I have been 
looking for more technical info explanation as to why they are supposed to be 
'awesome'... 

This video provides an independent, solid non biased tech opinion as to why.  

Just looking for confirmation of my understanding..

  One kick-ass antenna.

      Interesting info.. 

      So if we can use sector antenna which have 36/37/or 53 db of Front to 
back ratio, then these would be some serious kick ass antennas ?

        Hi Ken, 

        You are correct about ATPC taking care of equalizing the UL RSSI at the 
AP. 

        For downlink, as long as the antenna has good F/B ratio (32 dB like you 
indicated) and the back-to-back APs are set to the same Tx power, it should 
help. But maintaining 32 dB F/B ratio throughout the beam-width of the antenna 
can be a challenge. 


        Thanks,
        Sriram

          It probably seems that F/B ratio doesn’t need explaining.  The 
biggest hurdle is probably when WISPs start looking at third party antennas and 
other shiny objects (like price and antenna gain) distract them from looking 
for a F/B spec around 32 dB if they ever want to do frequency reuse.  The main 
thing this video probably does is to focus on why F/B ratio is important, even 
with GPS sync.

          I would add that uplink interference can be worse because of varying 
distance to SMs.  A near SM can blast through the backside of the sector and 
overwhelm the signal from a distant SM on the front side.  ATPC can help with 
uplink interference by at least equalizing the received levels from near and 
far SMs, but ATPC typically doesn’t help with downlink interference.

          Hello,
          We just uploaded a video about F/B ratio on our community forum. 
Curious to get some feedback from all the experts here.

          I really wish I could find a custom cable manufacturer who I could 
have make these for me again.   
          The company I was having make them kept raising the per piece prices 
and also  the minimum order... then was shocked when I refused to order several 
years worth for twice what I was currently charging my customers.

            That would need to be a 6p6c/rj12. You could easily buy that or 
anything like it, clip the rj plug off and crimp a new properly wired rj12 on 
it.

            The best kits were the ones Forrest had made that were molded and 
are no longer made. And of course every freakin tech lost them.

I"m pretty sure that although Monoprice has everything else, including 
completely outfitting your elementary school band, they don't have these 
adapters.

                      Does anybody sell the RJ14 to Headphone jack premade at a 
reasonable price, <$10?  I used to have a pile of them, but I Can't find them 
now, and I'm too lazy to go get the components to make one.

                      I think once upon a time, someone was selling a default 
plug and headphone adapter in a combo pack.
