On a FM Radio tower we have a 12.5db Omni antani with a 3db downtilt and at my home which I want to make into a relay I have tried several directional antani's.
The 14db Backfire directional signal shows recieve -74 transmit -79 and the other day I switched it for a vagi directional and shows a signal recieve of -69 transmit of -73.
The house antani is mounted to the chimney with the routerboard mounted directly under the antani.
I purchased and switched out all of my radios to the Sanyo 400mw a/b/g cards yesterday as well.
The link is 3 miles line of site from hill top to hilltop but my house chimney is on the back of the house and the peak of the house between the antani's. I have raised the antani and looks like it should clear the peak.
On 802.11b I am only able to get a 1m/1m connection and sometimes it will pop up to 5.5m but never stays.
What can I do to increase the bandwidth when I know that the singal to noise ratio is quite good?
There is no earth ground on the chimney antani. All of the cables are new and the right type.
I have other connections to the radio tower that are futher in distance through some trees that stay at 5.5M so I don't think there is a problem with the radio tower relay.
