Ubnt 90 are really 60, and The 120 are really 90. Gino A.

I'd really, really like some 60's, and UBNT already has 90s.

Actually, if I had my way, I'd prefer under 45 deg. Without detailed specs for the antennas, to understand what the product would be adding, its hard to suggest the market for each. UBNT makes wonderful and affordable 90 and 120 deg antennas, and if someone wants 90 or 120, I dont see why anyone would buy anything different than the proven product already available. (unless KP's antennas add something).. What I can say is that there are not any 60 deg dual pol high quality sectors on the market today, and there is a need for such a product. Admittedly, I tend to use 90 degs now. But I'd use more 60 deg, if they were available, even if it meant not gaining 360 deg coverage. I believe a combination of 5.8 and 5.3/4 is needed in combination to gain 360 coverage. In Urban and heavilly saturated suburban environments 90-120 degree antennas are almost unusable, atleast not at high modulations. The secret to a successful WISP is getting the highest modulations possible so they get the most capacity. And its better to have more capacity for limited coverage, than not enough capacity for full coverage, because with a more powerful offering, the take rate will be higher in the narrower coverage. It is true, that today, with UBNT only certified in 5.8 MIMO, 60 deg antennas would not likely safely enable full 360 degree coverage in most cases, prior to sync, and maybe not even then with noise floors. And as well, low density would warrant cost savings of fewer sectors. And obtaining 360deg is more important in low density areas. I'm sure this is why 120 and 90s are more attractive to rural WISPs. But the needs are much different for noisy Suburban/Urban. 120-90 deg antennas are to risky to use in urban cases. It should also be noted that spectrum reuse is sometimes possible, in Urban areas, mounted on opposite sides of penthouses, even without syncing, and often 10Mhz channels can be used to gain the coverage. Urban will choose 10Mhz, if they have a low colo cost, and can prove that higher modulation is achievable with less noise as a result of narrower sectors. So the decission may come down to which market segment KP wants to target, rural versus urban. And if they want a unique product, or compete head to head with others that have equivellent products.

We are trying to decide which degree Ubiquiti sectors to release in December. Our production line can handle two of the three for a mid December release date and want your feedback. The 120 degree version is pretty much a lock but we want your opinion between the 90s or 60s so we release the sectors you require. Please reply to the list or send me an email directly as your response will weigh heavily on our decision.
