Re: pop goes my fresh AP
On the roof there is - no power, but a taxi firm has a PMR omni about 3 metres long not sure what frequency but it could be 854Mhz as it has that written on the omni, seems odd though as I would have thought it would be VHF / UHF
The Osbridge is in a plastic box mounted onto the aluminium pole the omni is on. I 95% sure that the metal bracket that the Osbridge has only bolts onto the plastic of the box (no back plate)
The WR54G is in a custom water-tight plastic box with a metal back plate which is all connected up to the pole with the parabolic via a metal bracket.
Non of the antenna on the roof are earthed, neither mine nor the PMR.
I have 3 other osbridges mounted in a very similar way that have not shown this problem, they have all been in use longer too, (nearly 2 years)
It has been suggested to me that it could be an SWR problem on the omni as it is the only one of that type I have. I've orderd another one from my usual source with more believable gain figures too. »www.stelladoradus.com 10dbi 2.4gh omni. |

Wind over plastic creates static electricity, and I am willing to bet that this is where Your problem lies.:D
