Re: Will this hurt my radio?
said by Get Wireless  :said by MicroWISP :I'm with John and ehenry on this. I use the same gear and if it's "too loud" at close range I turn it down first, rotate it 180 degrees out of phase second, 180 degrees is not out of phase, 90 degrees is out of phase. 180 degrees puts your Tranzeo unit upside down. So youre not putting it in a different polarization, just phase? I did not know that 180 degrees was different, I have noticed on our alvarion VL gear that we do a sight survey with the radio upside down so we can see the bars, but when we wount it, the signal is about 10% higher. I just attributed that to dialing in the pointg when its mounted, thats interesting. |

Oops, lol, you are right get wireless, that's what I meant but it was late and I wasn't thinking. By the way, we have one Tranzeo upside down that's been up for two years that way working great! Installer was paying attention to polarity but not the writing on the box, lol. Have a great day!

Nothing changes by mounting an antenna upside down unless it had electrical downtilt built in. Now it's uptilt and I would never leave any antenna that way as it is so easy for water to go down the CAT5 through the ethernet coupler. |

said by shorthairedp :how would you attenuate an integrated radio? You can pretty much bet that if the received signal is that hot the transmitted signal is bombing into the AP at a high level too. Any standard attenuator which can also dissipate the required power will work both ways on the same antenna lead.

Any time a unit is cracked open and aftermarket parts are rigged in, I have a very hard time considering that "professional" |

1 edit | Yeah, I misread your post (having started this with wattmeters, etc. in another thread) and indeed an "integrated" radio won't be much use with an external attenuator. Probably would be a better idea to use the correct equipment in the first place instead of trying to hack something together like metal screens and foam. That would look really "professional" too, right?

to a geek like me, a screen mesh covered piece of foam mounted in front of a radio would look like art, but a customer may question the quality of work. |

So what is wrong with the idea of reducing the potential of the transmission path by pointing the antenner half way up to Jupiter ? I've seen no arguments against that very clean, easy and rather obvious solution.

So what is wrong with the idea of reducing the potential of the transmission path by pointing the antenner half way up to Jupiter ? I've seen no arguments against that very clean, easy and rather obvious solution. We know that pointing away works. But this links is quite a drive to get to and we are trying to figure out a way to change without having to physically move the radio. The screen mesh in front of the radio is something we have joked about, but i don't think we would ever do it to someone else radio. |

| I am planning on changing the transmit power to below 0 but i was looking for an answer on the ATPC. As per tranzeo, they don't think it will work. I asked them the same question and this is the answer i got.
"The ATPC should regulate all power appropriately for any distance link."
And again he said it wouldn't hurt with the signal being that low. Wish i could get that in writing. |

No downtilt built in, and Tranzeo panelized integrated units' CAT5 connectors are on the back of the units and completely independent of radio position (you adjust the placement of the weatherproof cover accordingly) so there is no cause for alarm on the water damage. |

Good thing is that you can do this remotely. I am saying only go 5 at a time just in case (really doubtful but is has happened!) you lose connectivity to the AP by dropping the power level too low, and then you have to do a truck roll. Give it a shot, you can't hurt anything and it will only take you 5 minutes.

I also think putting metal meshing in front of the panel is a horrible idea. I would not dream of doing such a thing. Wouldn't the signal reflect off of the metal right back into the radio causing it to lose it's sensitivity? That to me would be worse than keeping it the way it is with a high signal level. We always just point it away from the other radio if turning down the power does not do enough and/or change polarization. |
