Every time you double the distance, you lose 6 dB. You could try some incremental testing and look at received signal strengths.
I am guessing a problem with the radio.

Or did you just put the FSK AP on the vertical port for testing before swapping to the 450 AP? It will sit at 8X/1X QPSK MIMO-A while scanning to listen for beacons, so that is normal. I think you need to figure out why the SM can't hear the AP at range. Could be bad/damaged SM or AP. Do you have another SM or AP to try? Or RF pigtails between the AP and antenna. Easy way to get some idea of what's going on is to run the spectrum analyzer on the AP. Does it see anything at all?

So if it registers at 1x…12feet in from the of ap then it would make sense that it would not see anything if I try it at a mile Guess I will have to pass traffic through it to see if it works from what you guys are telling me I know for a fact that the sector antenna works because I attached a pmp100 AP to it and that registered without any issues…do you think me plugging a pmp100 into the sector antenna would cause this?

If you had software on them older than 13.2 I believe, and you also had an AP where the factory reversed the pigtails internally, your beacons would end up on horizontal instead of vertical and the SM probably wouldn't hear it. You say you're getting 8X/1X but it's also not registering. That does not compute. As other have suggested, try locking down the SM's scan list to the exact frequency and channel bandwidth that the AP is on. Tone alignment helps. If you can get a laptop, tablet, phone, etc. and look at the Tools > AP Eval page on the SM, does anything show up there? That's one of the first things our techs are supposed to do when troubleshooting on-site. If it's obviously not an alignment issue, log in and look at the AP eval.

It's always going to show 8X capable (or 2X for FSK, 3X for 430). After the / is what you need to pay attention to. Also, the uplink and downlink are independent. On the AP session status page (power tab), that's the downlink rate to that SM. On the SM main page, link status, etc., that's the uplink rate to the AP. What band is this? 2.4, 3.6, 5.4 or 5.7? And what software version do you have on the radios? It'd be best to stick with 13.2.1 for now. For the longest time I too thought this was backwards. I assure you it's correct.
