Hi Olympe!
As Nigel stated in an earlier reply, the 450m probably will not help with this issue.
The power is stable (as there are 2 other AP’s at the site, with no issues at all (1 x 450i and 1 x 450m). They are all powered by " Cambium networks AC+DC Enhanced Power Injector" C000065L002C.
There has not been any radar-detects on this ap.

Hello Rambern,
Ok, keep working on this and let us know if there any update.
Sincerely yours,
Niragira Olympe
The angle of the reflection from the tower is -6.7°. The angle of the beam from the tower is -1.5°. In order to be sure of satisfactory performance you need 6dB attenuation to reflection relative to the main signal. Thus there needs to be at least 6dB reduction in antenna attenuation at 6.7-1.5=5°, and so a 6dB beamwidth of 10° is required. Thus an antenna beamwidth of about 7° or less is required. This is provided by antennas with 2ft (>600mm) vertical aperture.
The RFE UH-CC-5-24 antenna is excellent but not appropriate for this application. The elevation beamwidth is too wide to attenuate the reflection from the ground. It is 11° at 3dB and 16° at 6dB. As noted above, in order to be sure to attenuate the reflection sufficiently we need a 6dB beamwidth of 10°. The vertical aperture of this antenna is less than 459mm.
Excellent Nigel - we will have a look at what antennas are available to us, and get a hold of one that is within your specs.
