Teletronics 15-704 - MIMO Sector Ant 5.8GHz 16dBi @ 120deg
| Pros | Cons |
|---|---|
| Expandable to cross-polarized MIMO operation | F/B might be low |
| Broadband allows frequency agility | Pigtails might be needed? |
Laird SA4958-120-19-DP - 5GHz 19dBi MIMO Dual Pol Sector
| Pros | Cons |
|---|---|
| High gain | Narrow vertical beamwidth (4 deg) |
| Broadband | Pigtails might be needed? |
| High cost |
Laird SAH58-120-16-WB - 16dBi 120Deg 5.8GHz Wide Band HP
| Pros | Cons |
|---|---|
| Bottom connector will not require pigtails | High cost |
| >25dB F/B | Not as broadband, 5.4-5.85GHz only |
ARC ARC-VS5818SD1 - 16dBi Dual Polarization Variable Beamwidth (60-120deg)
| Prox | Cons |
|---|---|
| Can use MIMO technology down the line without changing antennas | Inconvenient location of RF ports, will need right angle adapter or jumper |
| Cost-effective | Unused port will need to be weather-proofed |
| DISPROVED:Can simply change angle of radiation to add more sectors to a site | Radiation patterns look too good to be true |
| Really wide bandwidth | Downtilt may shift if nuts/bolts loosen a bit, or if pressure is applied to antenna |
Closely located sector antennas can interfere with each other. In order to reduce this, shields can be manufactured. For the Ubiquiti line of antennas, commercial shields are available at about $100/ea. [http://www.rfarmor.com/] We use WaveGuard Sector Shields for these Ubiquiti sectors now. Far cheaper than the RF Armor sector shields.
