Re: 2.4gHz WLAN Segment through a bit of foliage?
said by Deven07 :
I can see through the tree(s) pretty well to the other side, but there definately is no clear window without any foliage present. You will be fine with 250mW TX power with 14dBi antenna, or 100mW TX power with 19dBi antenna.
I say this because I have longer links where I can barely see a light on the other side at night after all the leaves fall from the trees. |

|  Hey thanks for the great info that was just what I was looking for...some reassurance that it is within the realm of possibilities! You all are very helpful, thanks again! So I think Ill go ahead and roll the dice and buy the equipment to get this link going. Any suggestions as to any economical brands/models of bridge/antenna that you would reccomend? |

19dBi model.
You could use one of each model for this link - put the 19dBi at the end with more clearence. |

| Nice! Thanks lutful, the DLB2300 looks just right, especially with the built in POE. This solution will actually save me money and it looks like I'm getting way better equipment. The only question I have is the ground...have you used this or similar boxes and can tell me if there is a ground post built into the box that I can run ground wire from, or do I need a inline ethernet ground? Lightning is definately an issue in my neck of the woods! |

| Citel or Hyperlink or Teletronics CAT5 lightning protectors will add extra protection to Ethernet port on the DLB2300.
You could bond the PCB metal shield to the protector's ground lug with a heavy gauge wire and then ground the whole system, but there are many different ways.
BTW, very few radios integrate RJ45 lighting/surge protection directly on the PCB like the new DLB2700 PCB. So even if the radio PCB is grounded to metal enclosure, the CAT5 PoE and data signals are not fully protected.  |

| Just as a quick clarification, the DLB2700 PCB does not have the surge suppressor built into it. The ethernet surge suppressor is a standalone unit inside the enclosure that grounds to the rest of the internal chasis and then to the external ground screw. You can see the pics on the FCC site for FCC ID RIW-ZW-2000 from Zinwell.
