The KPPA-3GHZ-DPOMA-WC-2 is a 3 GHz 13 dBi dual polarized H/V Omni antenna with an integrated Cambium ePMP radio case (also fits UBNT radios nicely). Using an omni antenna like this is a practical solution when you are setting up a new tower and cannot justify the cost of putting up 3, 4 or more radios and sectors.
If you only require a radius of 5 to 6 miles, the KPPA-3GHZ-DPOMA-WC-2 omni antenna may be the solution you are looking for. This omni antenna utilizes dual polarized H/V and works well with the Cambium ePMP-series equipment as well as UBNT radios. This Omni antenna is equipped with a versatile pipe-to-pipe style mount. These dual pol H/V omnis will provide you a very consistent pattern with no null zones.
